as long as Dave Mustaine doesn't involve himself i'd say the shark. not only can zombies not swimm they's never be able to get through the sharkskin to the brain.

zombie's may not be able to swim but they can still walk under water!
a great white would fuck owt up though
Mustaine could take Rambo on.
I bet Mustaine could kick anyone's ass.
