Gee, I wonder how Triathalon got on the team? Oh, I know, because Kurt Busiek created him!
It’s kind of ironic: The comic has a storyline about how The Avengers should have more black people, but none of the black heroes they know want to get on the team simply as a result of a quota-based affirmative program. So, Busiek resorts to nepotism. I know, that analysis is a little meta. But it’s still ironic, isn’t it?
