Johnny Rancid's first appearance was a heated battle with Robin. The battle spanned much of the city, with Rancid driving straight up buildings and across bridge suspensions. Rancid was in control most of the fight, but was ultimately defeated.
Near the end of the series, he also has a battle with Mas and Menos.
He is never without his trademark motorcycle. It has a red, glowing pattern on it. His main weapon is a jagged blade that can fire energy blasts. Rancid can also transform into a more powerful form. This form has glowing red hair and tattoos, mimiking his bike.
