Zitz was originally a human game tester named Morgan Ziegler, who much like his buddies was transformed into a toad upon entering the Gamescape. He's the team's leader and most intelligent of the group, being differentiated from the other Battletoads by wearing a utility belt, gloves and a wrist computer, as well as studded knee pads. His advantage is not brute force, like Pimple's, which he compensates with his intelligence, in Battletoads Arcade he was the Balanced toad but in the reboot he is now the fastest and weakest and highly skilled toad. In the 2020 reboot, Zitz is shown to have a severe lack of self-confidence, often trying to assert his position as the team's leader.
