4. Brain Storm
Not gonna lie, the only reason I added Brain Storm to this list is because of his hilariously phallic looking helmet.
It's, uh, it's certainly something, isn't it?
Hee hee.
ANYWAY, let's actually talk about Brain Storm as a character. Born Axel Storm, which is 1000% the name of someone's Sonic the Hedgehog OC, Brain Storm built a helmet that allowed him to harness stellar energy. Not sure why the mechanical Marge Simpson up there couldn't build a less cumbersome looking helmet to do that, but whatever.
Believing that his brother had been killed by Green Lantern (due to a wacky mix-up), Axel attacked the Justice League, with predictable results. Later, he returned to fight them again, this time by striking them with various physical ailments.
He fuses the Flash's legs together so he can't run (which is hilarious), makes Green Arrow's arms disappear (which is somehow way funnier), blinds Superman (which is just a major jerk move), gives Green Lantern a stutter, and my favorite one of all, just gives Hawkman breathing problems. Like, that combination of things is really funny. Especially since he didn't even think highly enough of Hawkman to give him a character-specific ailment.
Best Justice League issue of all time? I would say yes.
