T-Rex: The Fantastic Four, who FAMOUSLY got their powers from cosmic rays, should meet a supervillain who ALREADY has all their powers...

T-Rex: ...and the best part is, his name is Ray! COSMIC RAY!!

Dromiceiomimus: Well, they've already met the Super Skrull, who is a shapeshifter villain who has all their powers at once.
T-Rex: Oh.
Dromiceiomimus: Yeah, he showed up in the 1963 in just their eighteenth issue, so you are sixty years behind the times here.

Utahraptor: And one "Cosmic" Raymond showed up in an FF annual in the 90s!
T-Rex: You're KIDDING.

Utahraptor: Nope. Turns out these working professionals have ALREADY thought of these ideas you're dashing off the top of your head.
T-Rex: DANG IT. Okay, well, has Iron Man ever had rain on his wedding day, thereby becoming Irony Man?

Off panel: No, but he IS getting married in the comics next month, so -
T-Rex: Too late! TOO LATE!
T-Rex: I GOT THERE FIRST, IT'S ME, T-REX DID IT FIRST
