Dr. Frumpus Croid was a Tharpod Paradoxologist, Astrophysicist, and Lombax Whisperer who lived on planet Magnus. He lived at an outpost in the Terawatt Forest. He held the key to the mystery of the Creature Collector. His colleague and closest friend was Nevo Binklemeyer. Dr. Croid also owned a series of secret labs scattered around planet Magnus. When each lab was completed by the heroes, a RYNO VI Protosuit part was acquired. Croid had built a small army of loyal robots to defend his base on Terrawatt Forest, additionally giving him complete control of the Phonica Moon thanks to them.
