Gammatron's Season 3.0 appearance.
Gammatron was a robot that fought in the first three televised seasons of BattleBots. It was a walkerbot (technically a shufflebot) that had a variety of weapons: A spinning helicopter blade, a pickaxe on a rotating turret, and a sawblade on an arm on the same turret. It peformed decently in BattleBots, reaching the quarterfinals of Season 1.0 but never winning another match. Due to it being a walker, it had a 100 pound weight advantage over other heavyweights.
After Season 3.0, Gammatron was retired because it no longer applied for the walker weight bonus and replaced with a superheavyweight named Gammacide. The builder of Gammatron also competed in the 1996 Robot Wars event and the first two BattleBots competitions with Namreko 3000.
