Bob is a character in Ratchet & Clank, with a cameo in Up Your Arsenal. He is a robotics engineer and inventor, with a roboshack in Jowai Resort on planet Pokitaru, and the elder brother of Al, who provided Clank the Thruster-Pack. Bob is a rather skinny, yellowish man with pointy ears and short brown hair, who wears orange shoes, greenish pants, and a black shirt with a white lab coat over it. He wears green glasses with a telescope attached to one side, much like Al. Bob taught Al much of what he knows.
During "Help the resort owner", Ratchet and Clank were introduced to Bob, as the Resort Owner recommended they visit him about a lock blocking their entry to the jet fighter garage. When they approached him, Bob recognized Al's work on Clank and offered the Thruster-Pack as an upgrade for 2,000 bolts, which would allow them to open the lock. Ratchet and Clank then purchased the Thruster-Pack and opened the lock to the fighter garage.
Bob later watched the premiere for the Secret Agent Clank movie.
Behind the scenes
In the 2016 re-imagined game, Bob no longer appears on Pokitaru, and his roboshack is replaced with a standard, inaccessible hut. Instead, Ratchet and Clank meet Al in roughly the same location, who is present on the planet for a comic book convention, and Al is the one who provides Clank with the Thruster-Pack.
