Drakus

Berserko was a minor villain, appearing in only one episode of the classic 1987 TMNT series. It's revealed that HE is the original designer of the Technodrome, and he helped Krang build it. However, once it was finished, Krang used it to blast Berserko out of Dimension X, and destroy his home world.

He returned, centuries later, with a new mission: Revenge.

Berserko is as tough as he looks. He posses incredibly unmatched fire power, as well as other highly advanced alien weaponry. He is also very intelligent, and a master weapons designer. Not only did he create the Technodrome, he also built an entire army of deadly robots he calls, "Cyber Dromes". And, he built a super tank which he names, "The Annihilator", which according to him, has TWENTY times the Technodrome's power!
