Optimus Prime is a character from the Transformers series. He is a member and the subsequent leader of the Autobots, the heroic faction of the Transformers. He transforms into a semi-trailer truck. He is a pacifist and fights only when he has to. He fights with his energon axe and ion blaster. Inside his chest, he carries a powerful weapon, the matrix of leadership.
In M.U.G.E.N, Optimus Prime was made twice, once by Omega Supreme and again by Kain the Supreme. Both versions appear to use custom sprites and are based off of Optimus's 80's incarnation.
Omega Supreme's version was the first Optimus Prime made for M.U.G.E.N and is an edit of Kung Fu Man, like all of Omega Supreme's characters. His stats are rather high in comparison to the average character and a few of his attacks deal large amounts of damage, even if one were to lower his attack stat. His Truck Transformation and Axe Upper moves have EX versions, even though all of his other moves don't have an EX version. He has some of Kung Fu Man's moves, like his Truck Transformation, Triple Truck Transformation, and Super Ax Upper mirroring the Kung Fu Palm, the Triple Kung Fu Palm, and the Smash Kung Fu Upper, respectively.
This Optimus prime is a three-button character, using , and for his light, medium and heavy attacks, respectively. The amount of power a hyper uses depends on the button pressed, like in Street Fighter Alpha 3.
