Final Smash: Spartan Laser

Chief whips out the Spartan Laser, charges, and fires. The attack is basically a one hit KO. Firing an erratic-shaped beam, it's very fast and nearly impossible to avoic in time, dealing 150% damage in one hit. The only possible way to survive would be if you're boxed in, much like Marth's Critical Hit.
