Mack

Mack can refer to one of two characters:

Mack the Zigzagoon, who was a hero turned antihero who was fully replaced in late 2015 ("Hero Mack")

Mack (Goji's Blog), who was a murderer in several stories, mainly the Goji's Blog series ("Villain Mack")

KP is heavily based on Mack the Zigzagoon, and therefore is rarely referred to as Mack. For his page, see Kaypee.
