Master Zaprobo (Defiant)
From Ouroboros Portal
Formerly Professor Zaphod Robotnik, a noted Research Scientist in Paragon City, and creator of the ZR Series Automated Combat System. After the closure of his robotics project, he was driven to exile and insanity by his own creations.
Freed by Arachnos and given full reign to develop his robotic creations he now lives only to perfect the destructive power of his inventions through aggressive field testing and hostile acquisitions - chief among them the ZR Aegis Transponder and ZR Series Automated Combat System.
He is now the Chief Scientist of Arachnos Research and Development (ARAD), reporting to Black Scorpion.
