The Proton Cannon is one of the signature Hyper moves of both Iron Man and War Machine, first appearing in Marvel Super Heroes.
Executed with 
, Iron Man summons a huge cannon which he holds, then shoots a large beam that hits the opponent multiple times. In Marvel vs. Capcom 2, due to the inclusion of both characters, War Machine's version of the move was modified to rapid fire missiles instead of an energy beam. In Marvel vs. Capcom 3 and Ultimate Marvel vs. Capcom 3, Iron Man also possesses a diagonal version known as the Angled Proton Cannon, which can be executed by pressing 
, which fires the cannon at a 45 degree angle upward instead.
In M.U.G.E.N, many characters have the Proton Cannon as a Hyper, to the point of it being considered a cliché along with Shun Goku Satsu and Road Roller Da!; it is very common for characters to have all three as Hypers, especially if they are original creations.
