Yellow belts?

Nice question, Custom. Might be a stumper.

That's pretty general, and true of all comic book characters (except maybe Alice Cooper and Pope John Paul II). I'm not saying the factor I'm looking for is unique to these six characters; in fact it's true of a lot of major villains. But it's something specific, not common to all comic book characters, that these six share.

I'm sure Archie wore a yellow belt sometime in the last 70 years, but I don't think Green Arrow or Martian Manhunter ever did. Good try, though.

They took over an already-running book at some point in their career?

They debuted in titles that did not bear their name?

No; I don't think that could honestly be said of Green Arrow, and definitely not Wonder Woman (she was the star of Sensation Comics from the start).

Not that either...but you're getting warmer!

They were not on the cover of their debut comics?

IgMo gets it!! Archie Andrews first appeared in Pep Comics #22; Wonder Woman in All-Star Comics #8; Aquaman and Green Arrow both in More Fun Comics #73; Superboy in More Fun #101; and Martian Manhunter in Detective Comics #225. None of these characters appeared on those covers!

Take it away, Iggster!

What indignity did Superboy-Prime suffer in his childhood?

He was named after a comic book character?

--wyld

That is correct. He was teased for being named "Clark Kent."

Earth-Prime can be a hard place to grow up.

Gar Logan, known interchangeably as Beast Boy and Changeling, has been associated primarily with two superteams. Name them, and name two other heroes who have appeared on both rosters.
