Have Wolverine and Beast in your party. Choose Beast and face Wolverine. Press Throw and Beast will pick up Wolverine and hurl him at an enemy, doing a large amount of damage. Note: Rogue can also throw Wolverine just like Beast.
This is the signature move of Wolverine and Colossus combined (but can also be done with Beast). Play as either Colossus or Beast and press Square to throw Wolverine.
