Frenzy

フレンジー



The animated series accidentally swapped the color schemes for Rumble and Frenzy - Rumble was now colored as Frenzy and vice-versa.

In the animated series, Frenzy was not as prominent a character as Rumble, first appearing in the episode "Countdown To Extinction" and made few appearances after that, usually appearing alongside Rumble.
