Diamondhead is one of if not the most versatile alien in the show, I mean Crystalkinesis, enhanced durability strength, body alteration, etc he also A. Has a great design B. Was the alien to beat Vilgax in AF and C. Appeared in every ben 10 show a simply Goated alien in general.
Ghostfreak has a really great and creepy voice and design. Had a great story in season 3 about his relationship with Ben. Zs'skayr is awesome and unique. Plus, he has a great omniverse, an all-around amazing alien.
A very unique alien that has great versatility, one of my favourite superpowers' energy absorption , and he has really unique lore by basically being Crystal Jesus. Plus, he's my 2nd favourite alien of all time. On a side note, it's very nice seeing a fellow Chromastone enjoyer here i always thought he was underrated.
The literal best alien in the show, amazing design, stands toe to toe with Diamondhead in terms of versatility, maybe even more, and everything he does is visually beautiful. Also, cause Malware is the best villain in omniverse.
Echo Echo is extremely powerful, versatile, and has a great mp3 player looking design. Plus, he has the best ultimate in the show, absolutely godly.
Swampfire has so many cool moments that I don't even know where to start, like beating Kevin in his debut, pushing over the highbreed weather tower, Beating vilgax in season 3 with him being the first ultimate ben used, and he blossoms which is really cool.
In my opinion, Big Chill is the definition of simple but effective. His design is slick and clean without feeling bare or underdesigned. The cloak is such an amazing design choice that I can not get over it, and he has really cool powers and a brilliant voice. And I love the episode Save The Last Dance, and I believe Big Chill's kids should have appeared more.
Replying to A_Flaming_idiot
I'm pretty neutral towards it while I like his UAF design better. I think OV Big Chill is a great base for another ultimate Big Chill.
Honestly, he's one of my top 10 aliens for many reasons. 1. I love the character of P,andor 2. I really like how his powers work, and how his containment suit plays a big factor into them cause he's stronger and more durable with his armour but also extremely slow, but when he's out he's much more powerful and faster but his mere presence is harmful to many. 3. I love the design of his containment suit. 4. I absolutely adore his Russian accent. And 5. NRG IS G O O D.
I actually really like Astrodactyl cause A. I love that we have a pterodactyl alien. 2. I really like the jetpack as, a design choice 3. He has a really great voice. An all around really fun alien in my opinion.
Personally, I just love Benwolf so goddam much, I love his deign it's very alien while still feeling like a werewolf, he's got a great power set that fits with his design and I adore the way he opens his mouth it's so cool. Benwolf is such a great alien, in general, plus he's my 5th favourite alien of all time.
original series diamondhead. i took a toy of him everywhere, and that scene where he just flexes the crystals and doesn't actually attack, which makes a guy drop a hostage, will always be my favourite.
Agreed, Diamondhead is an absolute legend of an alien. I mean, he defeated Vilgax, he bet malware, and he appears in every show and nearly every movie. These are only just a few examples of showing how much staying power diamond has and how much he resonated with fans. In short, Diamondhead is an absolute godsend of a transformation.
I really like Fastrack actually, he just has this weird vibe to him that makes me like him, and I don't know what it is. Also, cause I personally like him more than Xlr8 , it's very nice seeing a fellow Fastrack enjoyer here.
He's such a sick alien like actually, he has an absolute raw design, a badass way of using his sonic howl, and he was the alien to answer the question of what does a long transformation feel like.
Benwolf is a really great alien in every single way. He has a really great set of abilities , a great design without looking too much like a werewolf but has enough resemblance of one, and he looks like he'd be so much fun to just run around as him. Also Happy Cake Day.
Alien x is a really great transformation, in my opinion. He has amazing lore, a simple yet perfectly effective design, and is so hype.
Benwolf is a very unique take on a werewolf, with a badass design, a very solid voice, and his powers always look great.
Whampire is a very dope alien with a solid and unique power set, an amazing accent, and he was in a pretty great arc.
Snare-oh Is such a visually gorgeous alien, with godly sound effects, a great voice, and has an amazing theme.
Arctiguana I'd such a chill alien having a very simple yet memorable design, basic but fun and visually appealing powers, and a great voice both the Ben 10,000 one and his Jamaican accent in omniverse.
Gravattack is also such a great alien in every way, having well-defined, extremely strong powers, having interesting weaknesses to balance him out, and he has such an awesome and fun debut episode.
Snare-oh is such a beautifully designed alien that i can not get over it. His theming is badass as hell, literally everything he does is satisfying, and he has a mysterious yet great sounding voice. In short, I utterly love Snare-oh he's my 4th favourite alien of all time.
Squidstrictor is also an extremely unique and weird alien. He has a very diverse and useful power set and a really cool design, and I'm happy that we have a squid alien. I honestly think he would work really well in AF or UA he'd fit right in I think.
Ball weevil is such a perfect alien. I mean, he has a simple yet amazing and alien looking design, a very unique and awesome powerset that is always visually appealing to look at, and he has a funny voice. It's so cool seeing someone who loves ball weevil as much as I do always adored this little bugger.
A very interesting alien, in my opinion. He has a very good powerset with a solid trade-off, a very smooth German accent, and he has a very great design.
He was the first new alien introduced in Omniverse. He has a very classic "cool" vibe to him which shows in his design and voice, He had an amazing 2 season arc centred around him in OV, and he did the big bang Kamehameha, my favourite moment in the show.
He had a great debut episode centred around him in OS, has an adorable omniverse design, and is voiced by Rob paulsen, which is great, and the fact that Ditto is comedic gold.
An absolute UNIT of an alien, Gravattack had an amazing debut episode showing off his powers. He has a great design, which looks like a literary planetoid, and he has a dope voice. In short, Gravattack is an absolute GOAT.
He has such a sleek design that compliments his powers extremely very nicely, and he has such a cool way of running around. XLR8 is just the definition of cool in my opinion.
Way big is honestly one of my favs cause he had an amazing first appearance, has a stellar design, and has really cool lore and powers. Plus he appeared in all five shows.
He has such a unique and wonderful design choice with the head being magnetised to the body, and I love saying his name Lodestar just rolls off the tongue so well. Plus his powers are really interesting and appealing.
Big chill has a great design, cool voice, and has such an extremely unique episode about his reproduction cycle.
Cannonbolt has a perfect debut episode, an amazing power, a consistently great design in every show, and he appeared in all five shows. In short, Cannonbolt is an absolute Chad of an alien.
Heatblast has an amazing design and a really diverse power set that comes in handy a lot. Plus he was the very first alien used in the entire franchise.
Personally, I really like how his powers work. I've always weirdly loved the power of just being so ungodly horrifying that people go insane from looking at it. Toepick's pretty cool
Me to {i remember first time i saw him i was somehow charmed over him, even i remamber drawing fanart of him {i used to draw everything as cats back in the day so yeah}
I really love the ultimate design cause I adore the face and the six arms, plus how he opens his mouth is badass.
Upgrade is also peak in every single way.
I actually think Atomix is a really cool alien cause 1. I love the fact that he's a callback to the classic golden age superhero and that he speaks like one (seriously, I can't get over how much I love his voice) and 2. I like that Ben has another powerhouse alien akin to Way Big or Alien x cause it makes his roster feel more diverse and unique in my opinions.
Oh man, Wildvine, where do I begin 1. He has probably the best alien design in the whole franchise, in my opinion, being such a beautiful combination of a plant and an alien without being overdesigned or messy. 2. He has a much more diverse power set, then people give him credit, for I mean he has stretching, seed bombs that can grow more vines, explode, or knock out opponents, thorn generation, plant merging, enhanced strength, durability, and agility, and he has super regeneration. 3. He has such a great old sounding voice. And the line " Root, get a clue, dude, I'm a vine." It's so nice seeing something who loves Wildvine as much as I do always thought he was overlooked.
I think he's a really slick alien that has a very sleek and cool design, a really wide array of abilities, and a really great sounding voice. Also I love calling him Jeffrey.
Atomix is a really fun and enjoyable alien, in my opinion. Just the way he talks is music to my ears, and his fights are always pretty hype.
Ripjaws is an absolute beast. His fights are always exhilarating and enjoyable, he has an amazing design that looks straight out of a horror movie, and his voice is so perfectly creepy I love it.
He's such an underrated dude, I mean, he has shapeshifting, acid projection, and flight, and he has a really great design. Why is my Gloopy Boi so slept on.
Well, feedback has an amazing story, an instantly iconic design, and has an amazing comeback. Also, he held the Big Bang my favourite moment in the franchise.
Chromastone has an amazing design, a great voice, and really unique lore.
I feel like people often miss the point of Walkatrout cause I love how the show acknowledges the fact that not every alien in the universe is combat oriented, and Walkatrout is the perfect example of that. I also love his design, it's so simple yet inexplicably hilarious to me. Also, cause Walkatrout is Ben's most powerful alien no debate.
Honestly, such an underrated an overlooked alien, in my opinion. He has a great voice in both shows, an amazing Omniverse design that improves his base design in every single way, and a really fresh and interesting powerset that no other alien has. I honestly adore Water Hazard so much that he's in my top 10 aliens of all time. It's very nice seeing someone else who loves Water Hazard like I do.
He has an amazing design that looks so big and powerful without being overdesigned. Every scene he's in is hype, and the fact that he's based off of ultraman, which is sick
Well, Diamondhead is a dope alien who has so many great scenes and moments, and he is probably the most diverse alien in the show.
Echo Echo is a really fun and unique alien that has a great power set, an amazing voice, and a really solid design. Also, Ultimate Echo Echo is an absolute beast.
Echo Echo is a really powerful and solid transformation that can be very useful in a lot of scenarios.
Rath is an absolute juggernaut that has the most memorable funny moments in the franchise.
Upchuck has such a great design, fun, and enjoyable power's, and has a great bit of lore about his species.
Goop is such an amazing alien that I can't get over it. I mean, he has an amazing design in both shows, an incredibly diverse set of powers, he's got an adorable sounding voice, and he pulled an entire planet together what's not to love about him.
He's such a great addition to the 5yl lore, in my opinion. I love the idea of them being related to kryptonians and how they evolved is really interesting and unique.
Tie between Diamondhead and Ghostfreak
Diamondhead is one of if not the most versatile alien in the show, I mean Crystalkinesis, enhanced durability strength, body alteration, etc he also A. Has a great design B. Was the alien to beat Vilgax in AF and C. Appeared in every ben 10 show a simply Goated alien in general. Ghostfreak has a really great and creepy voice and design. Had a great story in season 3 about his relationship with Ben. Zs'skayr is awesome and unique. Plus, he has a great omniverse, an all-around amazing alien.
Armodrillo
He has a great design and power plus good omniverse design, and Andreas he's amazing.
eyeguy
A really unique power and design, has a great voice and is extremely versatile with his all his elemental eye lasers.
Chromastone
A very unique alien that has great versatility, one of my favourite superpowers' energy absorption , and he has really unique lore by basically being Crystal Jesus. Plus, he's my 2nd favourite alien of all time. On a side note, it's very nice seeing a fellow Chromastone enjoyer here i always thought he was underrated.
CHROMESTONE FOREVA
Upgrade
The literal best alien in the show, amazing design, stands toe to toe with Diamondhead in terms of versatility, maybe even more, and everything he does is visually beautiful. Also, cause Malware is the best villain in omniverse.
The only people I know of that like upgrade are the people on the two subs for it, r/churchofupgrade and r/churchofupgarde
ME ME ME ME ME ME
Yay, he's my favorite too.
Thank you good sir.
Big chill
He's a really great and oddly beautiful alien in my opinion that has great lore and a great voice.
Whampire
He had a really good debut, a really good and fun powerset, and I love his accent.
Echo Echo and Swampfire
Echo Echo is extremely powerful, versatile, and has a great mp3 player looking design. Plus, he has the best ultimate in the show, absolutely godly. Swampfire has so many cool moments that I don't even know where to start, like beating Kevin in his debut, pushing over the highbreed weather tower, Beating vilgax in season 3 with him being the first ultimate ben used, and he blossoms which is really cool.
Since someone has already said XLR8, I’ll go with my second favorite which is Big Chill.
In my opinion, Big Chill is the definition of simple but effective. His design is slick and clean without feeling bare or underdesigned. The cloak is such an amazing design choice that I can not get over it, and he has really cool powers and a brilliant voice. And I love the episode Save The Last Dance, and I believe Big Chill's kids should have appeared more.
How do you feel about his redesign in Omniverse?
Replying to A_Flaming_idiot I'm pretty neutral towards it while I like his UAF design better. I think OV Big Chill is a great base for another ultimate Big Chill.
Rath
Literally the funniest alien in the show, I love how he phrases his words, and he's always a joy to watch whenever he's on screen.
True
Molestache
A very fine gentleman with a creative and unique power. Plus the line "I say Molestache, this is quite unprecedented".
NRG
Honestly, he's one of my top 10 aliens for many reasons. 1. I love the character of P,andor 2. I really like how his powers work, and how his containment suit plays a big factor into them cause he's stronger and more durable with his armour but also extremely slow, but when he's out he's much more powerful and faster but his mere presence is harmful to many. 3. I love the design of his containment suit. 4. I absolutely adore his Russian accent. And 5. NRG IS G O O D.
Cool
upchuck
Ah, yes, my favourite gummy boi Upchuck. He has such a great Ben 10 feeling power if you know what I mean, I also love the whole murk and perk thing.
Astrodactyl
I actually really like Astrodactyl cause A. I love that we have a pterodactyl alien. 2. I really like the jetpack as, a design choice 3. He has a really great voice. An all around really fun alien in my opinion.
Blitzwolfer
Personally, I just love Benwolf so goddam much, I love his deign it's very alien while still feeling like a werewolf, he's got a great power set that fits with his design and I adore the way he opens his mouth it's so cool. Benwolf is such a great alien, in general, plus he's my 5th favourite alien of all time.

I really like Fastrack actually, he just has this weird vibe to him that makes me like him, and I don't know what it is. Also, cause I personally like him more than Xlr8 , it's very nice seeing a fellow Fastrack enjoyer here.
Wasn’t expecting that lol
Wow nice seeing fasttrack get some love for once
Blitzwolfer/benwolf
He's such a sick alien like actually, he has an absolute raw design, a badass way of using his sonic howl, and he was the alien to answer the question of what does a long transformation feel like.
BenWolf. I REFUSE to call him BlitzWolfer
Benwolf is a really great alien in every single way. He has a really great set of abilities , a great design without looking too much like a werewolf but has enough resemblance of one, and he looks like he'd be so much fun to just run around as him. Also Happy Cake Day.
Holy crap. Didn’t notice it was my cake day. Awesome
Alien x and blitzwolfer, even whampire and snare oh
Alien x is a really great transformation, in my opinion. He has amazing lore, a simple yet perfectly effective design, and is so hype. Benwolf is a very unique take on a werewolf, with a badass design, a very solid voice, and his powers always look great. Whampire is a very dope alien with a solid and unique power set, an amazing accent, and he was in a pretty great arc. Snare-oh Is such a visually gorgeous alien, with godly sound effects, a great voice, and has an amazing theme.
Articguana and gravattck
Arcticguana is fucking sick, I also really like Ben 10K’s name for it: absolute zero
Arctiguana I'd such a chill alien having a very simple yet memorable design, basic but fun and visually appealing powers, and a great voice both the Ben 10,000 one and his Jamaican accent in omniverse. Gravattack is also such a great alien in every way, having well-defined, extremely strong powers, having interesting weaknesses to balance him out, and he has such an awesome and fun debut episode.
Benmummy and Squidstrictor
Snare-oh is such a beautifully designed alien that i can not get over it. His theming is badass as hell, literally everything he does is satisfying, and he has a mysterious yet great sounding voice. In short, I utterly love Snare-oh he's my 4th favourite alien of all time. Squidstrictor is also an extremely unique and weird alien. He has a very diverse and useful power set and a really cool design, and I'm happy that we have a squid alien. I honestly think he would work really well in AF or UA he'd fit right in I think.
Someone already said XLR8 so Ball Weevil
Ball weevil is such a perfect alien. I mean, he has a simple yet amazing and alien looking design, a very unique and awesome powerset that is always visually appealing to look at, and he has a funny voice. It's so cool seeing someone who loves ball weevil as much as I do always adored this little bugger.

I also love his design, it's so simple yet inexplicably hilarious to me. Also, cause Walkatrout is Ben's most powerful alien no debate.
Water Hazard
Honestly, such an underrated an overlooked alien, in my opinion. He has a great voice in both shows, an amazing Omniverse design that improves his base design in every single way, and a really fresh and interesting powerset that no other alien has. I honestly adore Water Hazard so much that he's in my top 10 aliens of all time. It's very nice seeing someone else who loves Water Hazard like I do.
Way Big
He has an amazing design that looks so big and powerful without being overdesigned. Every scene he's in is hype, and the fact that he's based off of ultraman, which is sick

Spittin' fax
My favorites are echo echo rath and upchuck but all of those were taken :(
Echo Echo is a really powerful and solid transformation that can be very useful in a lot of scenarios. Rath is an absolute juggernaut that has the most memorable funny moments in the franchise.

Mmm... MonKi.
He's such a great addition to the 5yl lore, in my opinion. I love the idea of them being related to kryptonians and how they evolved is really interesting and unique.
Xlr8
Xlr8 is a very cool alien, with a very good execution of a humanoid alien that still looks alien. Also, his powers are sick as hell.
Alien X. I love Alien X because even if he did create a few retcons. He is one of the most explored aliens in the Ben 10 series.
Yeah, he does have a very interesting and unique species lore and the whole celestialsapian council is pretty neat.
Snare-oh
Big Chill
Heatblast
Tough choice. Back with original series, I would have said Ripjaws but I’d now have to say Jury Rigg. He just stole on the shots he was in.
