Characters like Daken and Red Hulk seem to me like Dragon Ball Z villians. You've never ever heard of them until the point where they show up, but all of a sudden they're there and are the baddest kids on the block... for a while. Then they get relegated to second tier characters. I mean, can't you imagine how the commitee meeting to create Daken went?
"You know whose cool and ridiculously popular? That Wolverine... what else can we do to milk that cow?"
"Well... we could clone him, but make the clone a chick!"
"Thats brilliant, however I believe we may have already pulled that"
"huh... well, we could artificially implant his healing factor into a human, drive him nuts, and make him break the fourth wall with witty banter!"
"NO, NO, NO! Thats ludicris! A character like that would never become popular. I need real ideas here!"
"We could say he fathered a son! The kid could have the exact same powers as him!"
"... I like it. But we have to differiante him some how... he should have his middle claw come from some where other than the back of his hand!"
"His shoulder blades! Haha, get it? Cause its a blade... coming from his shoulder... nobody?"
"Shut it Quesada, no ones asking you! We'll just stick the middle claw on the under side of his wrists. Also... hell, lets give him some ridiculous power like pheremones or something"
"No, no, just ones that control emotions or something. Also, he'll be such a good fighter that he can always be where his enemy isn't looking. Johnson, see if we can trademark that!"
"This is going to make us richer than Jesus! Good job everyone, now someone pass the coke"
