The Ultra-Mech Scientist is a character in Ratchet & Clank with a cameo in Up Your Arsenal. He was hired by the blarg to design and mass-produce Ultra-Mech Unlimiteds on Quartu, designing an Ultra-Mech Pad that took smaller robots to transform them into massive, heavily armed killing machines within seconds. However, he was unaware that it was Chairman Drek who hired him. This technology is instead used to create Giant Clank. He is a friendly, well-meaning scientist who appears to be of the same species as Fred and the Inventor from Going Commando.
The Ultra-Mech Scientist was voiced by Neil Flynn.
Ratchet & Clank
The Scientist met Ratchet and Clank after "Find out more about the Ultra-Mech," where he was trying to destroy his Ultra-Mech Pad enlargement device to prevent more Ultra-Mechs from being created. Rather than destroying it, the three instead decided to use it to enlarge Clank, creating Giant Clank, for the mission, "Destroy the Ultra-Mechs." After the duo destroyed them, the Ultra-Mech Scientist was able to revert Clank to his original size, despite this only being possible in theory. The Scientist then gave Ratchet and Clank an infobot with a commercial for the Hologuise on Kalebo III, and mentioned that he recalibrated the controls on the pad to only allow Clank's specific circuit pattern.
Up Your Arsenal
The Ultra-Mech Scientist later appeared watching the premiere of the Secret Agent Clank film.
