Master Chief (halo 4) Vs bowser (supermario)

Let's assume bowser kidnaps princess peach. Mario goes into outer space to rescue her. He fights bowser but this time he loses for real and goes back home not knowing what else do. The UNSC discovers what happen and decides to send master chief to do the job. The UNSC infinity flies to the location where princess peach and being held at. A pelican drops off master chief. He finds princess peach but then he encounters bowser and is only up to him to take him down. So who would win.

What weapons does the Chief get?

@pacpanda: I would say a spartan laser and assault rifle.

Is this composite Bowser, or does he have a limited setup? If any of Bowser's powers or alternate forms are allowed, I'd say this fight would be over pretty quickly. Bowser with base stats and abilities might have a hard time dealing with Master-Chief's firepower though. Sometimes I wish it wasn't so hard to compare universes' physics.

chief

Probably Bowser
