There was an ancient filler featuring an early concept of a Boneguard. I eventually decided to keep them in the story and give them a complex, several episode long arc. But that's in the far future (after episode 20 maybe). This guy on the other hand, may show up or at least get mentioned in an upcoming episode. He's Number7 (codename Imhotep), the head of the research division, and the resident mad scientist.
