Zigzag first appears in The Infinity Gauntlet and is a normal dog living with a family in the aftermath of a great destruction.
Powers & Abilities
As a dog, Zigzag has the benefit of enhanced hearing and smell compared to a human which he uses to assist his human owners/friends in search of food and supplies. He was granted a Nova corps suit which allows him the power of flight. It was not shown or specified if he could fire energy blasts but more complex techniques may require greater intelligence. It is suspected the suit would offer Zigzag the same protection to a dog that it would a human.
