Red Hulk/YMMV

Arc Fatigue: The mystery of who Red Hulk was dragged on for roughly two years.
Hilarious in Hindsight: the Red Hulk, despite not being... well, red, made his debut as a What If story. Here, have a laugh.
Memetic Mutation: Ross's mustache and its incredible abilities.
My Real Daddy: Jeff Parker, the writer on the red Hulk's solo title, has done an amazing job of rebuilding and redeeming the character.
Villain Sue: Red Hulk initially goes around beating up people regardless of whether this makes any sense at all - the part where he picks up Thor's hammer (which can't be picked up by anybody less pure of heart than Thor or Captain America [granted, Thor was holding it at the time as well]) and beat the God of Thunder up with it. Then there's that great image of him riding the Silver Surfer's board while wielding Terrax's halberd (which provides the image for the Villain Sue page). Don't forget the part where he kills somebody who is explicitly immortal. In fairness, Red Hulk wasn't the first to do some of the things he's criticized for. (Badass Normal Baron Zemo even once killed said immortal, for example, who simply came back later. And the issue of Thor's hammer can be spotty.) However, such actions tend not to be glossed over when others do them, so it's not like Red Hulk is going to get a pass.
