3. Deadpool Corps
Kids love that Deadpool. The wisecracking mercenary is so popular that at one point Marvel was putting out no less than four different monthly Deadpool comic books. Given the title character's fondness for breaking the fourth wall, you could interpret that as a brilliant commentary of the over-saturation of certain superheroes on today's stands (we're lookin' at you, bub). Of course, that might be giving too much credit to a guy whose punchlines often end in "chimichanga."
Besides the main Merc with a Mouth, the Deadpool Corps consists of inevitable Rule 63 Lady Deadpool, as well as the self-explanatory Kidpool and Dogpool. Headpool, the disembodied noggin of un-Deadpool from Marvel Zombies rounds out the group because Congress still won't repeal 2009's A Zombie in Every Comic Book Act.
Deadpool is known for talking to himself, and sometimes there's more than one voice in his head. In Deadpool Corps, these multiple personalities are manifested in living beings that happen to think he's a moron -- and this is coming from people who are Deadpools. Again, thanks to the ambiguous nature of the character, you could see this as a reflection of Deadpool's own deep-seated hatred for himself. Or maybe it's just because someone needs to be the straight man so the comedy character can have someone to bounce his jokes off of. Deadpool Corps is either art or a shameless attempt at creating a new toy line for grown men. Maybe both.
2. Doom Patrol
Even though they premiered a few months before the X-Men, the Doom Patrol is not known as the premier team of bizarre people that came together under the wing of a mentor in a wheelchair to fight a self-proclaimed Evil Brotherhood. Maybe it has something to do with the batshit stupid villains like Animal-Vegetable-Mineral Man, or the fact that the team members keep dying horribly and getting replaced. But really, it's probably because the Doom Patrol somehow managed to be weirder than a comic about ostracized genetic freaks.
Maybe the most insane era of the Doom Patrol was helmed by writer/sorcerer Grant Morrison -- if you don't know who that is, imagine if Professor X went to Burning Man. As part of his run, Morrison co-created Danny the Street, who is literally made up of living buildings and pavement and can teleport at will. And he's a good guy! The villains were even more bizarre, including a vigilante named the Beard Hunter who kills/shaves people just because they have facial hair, keeping beard trophies around his waist. To date, his kill count includes dozens of Amish and everyone living in Portland, Oregon.
