Cyclops may be the leader of the X-Men, but the fan favourite has always been Wolverine.
Hugh Jackman plays the brusque mutant with a skeleton and retractable claws made of the ultra-powerful metallic alloy, adamantium. He has animal-like reflexes, and possesses the power to heal his body rapidly.
Also, he has a massive crush on Jean Grey (Famke Janssen), Cyclops' girl. But scruples have never been of great importance to Wolverine. Snikt.
