Evil Jack is Jack Douglass' evil doppelgänger who appeared in two videos, Ping Pong Battle and Weird DDR Battle.
Evil Jack's face is locked in Jack's Creeper Face and can communicate telepathically via his eyebrows. He speaks in a slightly nasally voice and always stands bolt upright, although there were slight differences between his two appearances.
In Ping Pong Battle, Evil Jack has very thick eyebrows and wears guyliner.
Evil Jack began the craze for the creeper face, one of Jack's now trademarks.
