Berzerk used to be a normal human being. After a confrontation between something unknown, Daddy Dearest sent him to the the 4th dimension, similar to what he did with Spirit.Hes been trapped there for 10 years. He has a circular white and black head, a trapezoid body shape that is not attached to any limbs, triangular legs and arms. When he goes "Berserk", the white side of his body becomes red. During "ERROR" he gains a glitchy filter and his eyes start crying goo.
