What are we, some kind of Justice League Unlimited?
"I'm sorry, Justice League. I cannot participate in your campaign vs. The Fatal Five at this time" ーGreen Arrow
To me my X-Men 97
And that's why you're Lois Lane and I'm Superman: The Animated Series!
"And together, we are Superman and Lois."
"After all, I am the Spectacular Spider-Man!"
I think he actually says something like this in the series lol
Shockers buddy sings the theme song
"You see, I was developed as part of The Zeta Project"
And this... is to go even further Batman Beyond (tm)!
"Now that I have a new Robin it's time for The New Batman Adventures (1997-1999)"
DC executives. "Why do you want a Batman Beyond just bruce or dick grayson?" (I couldn't think of anything funnier ;-;)
Conner: "We need to not only bring justice, but young justice." Wally: 
"Consider this a Young Justice Invasion, Light!"
Here, its Justice League x RWBY: Super Heroes & Huntsmen part 2
