Genius billionaire Tony Stark built the first Iron Man suit in a cave with a box of scraps, then spent decades upgrading it to go toe-to-toe with gods. The latest suit features repulsor beams, a uni-beam, nano-regeneration, and enough firepower to give small countries anxiety. Proof that with enough money, intelligence, and engineering, a man in a tin can can outclass most of the Marvel roster.

Born James Howlett but known to the world as Logan, Wolverine is the Canadian mutant who simply refuses to stay dead. His adamantium-laced skeleton is virtually indestructible, his healing factor can regenerate from a single cell, and his razor-sharp claws slice through anything short of Captain America's shield. Three centuries of combat experience make him the best there is at what he does—and what he does isn't very nice.
