Appearance: Evil Jack is simply huge, standing 7" in height and weighing 402 pounds. He is almost as tall as Zelgato, and he is taller and bigger than every other character in UGoI-ESF (only Mike Wolf comes close in size). His body is covered in scars (from fighting gears), and is he mostly bald except for a thick black buzzcut and a large busy beard. A thick mat of hair covers his chest as well.

Fighting Skills: When in close, Evil Jack will usually try to grab his opponent, and then execute a Bear Hug followed by a Pile Driver. Against agile opponents, the Footsweep and Suplex are favored. Really tough foes will find themselves on the receiving end of the Spinning Pile Driver, which is usually enough to put anyone out of the fight. The Spinning Clothesline is used to put down large numbers of people at once and is useful for fighting gangs and the like.

Special Abilities: Evil Jack is virtually fearless. He will absorb a great deal of punishment in order to get close to an opponent, at which point there is a good chance the fight will be all over.
