Growing up, I was a huge fan of the "What if?" series Marvel produced. The basic idea was taking a huge moment from the comics and spinning it off into a different direction.
"What if Aunt May died instead of Uncle Ben?"
"What if Spiderman joined the Fantastic Four?"
I was looking at the different lantern rings I got (it was part of a purchase) and started wondering "what if these were in Marvel? Who would be in the different corps?"
Some are very easy choices, while others can be a bit tricky.
So, let's start with the easy one: The Red Lanterns of rage.
This ring and its power is based on pure anger, heck they even vomit fire blood!
There's one standout in the Marvel Universe that belongs here: The Hulk. The green one, not the already red one. His powers are based on getting angry, so it makes obvious sense. Plus seeing the Hulk already powerful as he is and then puking fire blood? Awesome.
Wolverine would be another choice. "Bezerker Rage!"
You'd think a ton of villains would fall into this category, but realistically they aren't evil because they're angry, they're evil because they just are or want something. We'll get to that later.
A few other X-Men characters like Angel and Chamber could also fit in there. I would say X-23, but I can't stand that character.
Chamber is one of my favorites, who has been miss used like crazy. He's angry because he's missing half his face and chest, then can't really love Paige, then loses his powers and the X-Men dump him in a hospital like throwing out the trash, then he's cured by Apocalypse, but made to look in his image.
I'd be pissed too.
