When Slugger Johnson, a small-time crook, becomes of aware of the Fantastic Four intruding on the little patch of reality that the Shaper has created for him, he coerces the Shaper to transform him into the most fierce movie monster that he can think of. The end result is the War-Head, basically a huge Gorilla with a spheric head, from which he can shoot laser rays. 
 
Up to now, the War-Head appears in only one issue of the Fantastic Four (vol. 1 , Issue 137). Even though the monster is very strong, he is dealt with pretty quickly through the combined means of all conflicting parties existing in Johnson's warped reality.
