Bob is from the Infinity Point, the center of all things. The Infinity Point sees everything, but cant physically interact with other realms, as it can only interact with the In-between. Bob's first impression of Humans was REALLY bad. Humans attacked his home for no apparent reason. His original purpose was to protect his species, but his purpose was corrupt aftet the attack. Bob's allies, Larry, Hollow and the Lurker now help him in restarting everything.
Rob is now one of the last 2 of the Infinity Species thats purpose is not Corrupt. Rob's soul purpose now is to make sure Bob never gets control of the Infinity Point. If Bob ever did, nothing would be able to stop him. Rob is an angle-like being and completly the opposite of Bob. Rob also has a difficult time trusting humans, as he sees Bob's rage is the humans fault. (Which it kind of is.) if you gain Rob's trust, never break it.
Greetings, Robert.
