Shanak

, also known as "Bob" is a githzerai who was rescued from the plane of Pandemonium by Vox Machina. As an NPC, is played by Matthew Mercer.

Personality
Bob has been stuck in Pandemonium for long enough to have been driven mad by the howling winds. Notable traits of his madness include amnesia (including his real name) and possibly a compulsion to steal spell components.

Bob encountered Vox Machina shortly after they entered the Plane of Pandemonium. Vex dubbed him "Bob" when the party realized he did not remember his own name or much about his life. Bob asked the group for presents, though only Keyleth attempted to give him anything. In this time, he stole most of the group's valuable spell components (likely with his invisible mage hand).

After the group retrieved Grog's soul, they returned and retrieved their stolen components from Bob.
