FIGHT! (Regular Wolverine vs. 2003 Shredder[]
Wolverine charges forward while Shredder waits to assess Wolverine's skills.
Wolverine lunges when he gets within range of the Shredder, but he dodges the attack and counters it by stabbing Wolverine in his heart.
Shredder: (laugh) That was so easy.
Wolverine: (Getting up and panting) I'm not done yet.
Shredder: WHAT?! How are you still alive! I stabbed your heart!
Wolverine: Well, I didn't say I was human.
Both charge forward at the same time and there weapons clash.
They both aim to chop off the other's neck, but Wolverine's claws get stuck in the Shredder's shoulder plate and his claws get stuck in Wolverine's Adamantium Skeleton, so they must both retract their claws.
Wolverine maneuvers around The Shredder to cut his head off, and succeeds.
He walks away but the Shredder is still alive because he is an Utrom.
Silently, he uses his assassin skills to kill the Wolverine by slicing his head off and cutting it.
