Bartholomew

Bartholomew exists approximately 1000+ years into the future Ooo and was supposedly "built" by Marceline (or as she is later known: "The Empress") from BMO's recycled parts. He and his brothers (Mingus and Orange Juice) have been tasked with retrieving found artifacts to the Empress as part of their allegiance to her.

Appearance
Bartholomew stands approximately 1 2/3 of Marceline's height (based on the comic book artwork) and has a rigid metallic build similar to his brothers. He has red circular eyes and four red telescopic arms.
