Despite the fact that he is a villain, Ollie seems to be one of the most polite and cultured characters in the entire series, and can usually be seen reading books and drinking tea. He's also shown to be thoughtful on certain occasions. He's usually the one who gives his boss something cheese-related by accident, either forgetting Snaptrap's cheese allergy, or Snaptrap forgetting it himself. He tends to be Snaptrap's voice of reason, which he often ignores. He doesn't tend to do many evil things or act as mischievous as his partners, but he often does have ideas for evil plans. However, Snaptrap usually already has a plan, only to reveal it's just something he likes to do.
Ollie is a tan opossum with a long bent snout with uneven buck teeth, has a long neck, his teeth are yellow, he has blue eyes and a curled pink tail. His clothing usually consists of a lavender hat with a brim that is pink on the inside, a purple jacket with a pink collar and silver buttons, one at the front and two others on the cuffs, a light blue turtleneck underneath and light periwinkle ripped pants with lighter periwinkle vertical stripes. His hands are shown to have visible fingernails.
Relationships with other Characters
Ollie appears to be good friends with Snaptrap, although Snaptrap tends to boss him around a lot and often ignores his suggestions. In Snap Dad, it is mentioned that when Snaptrap had his wisdom teeth removed, Ollie stole some comic books for him to make him feel better. He also mentioned that Ollie and Francisco are like family to him.
Ollie seems to have a good friendship with Francisco, but it isn't usually shown. They tend to make a good team when they are paired up and always appear to get along with each other.
Ollie is a good friend to Larry and is loyal to him (such as in Doom and Gloom). However, before joining his G.L.O.O.M. agency, Ollie and Francisco were willing to throw sticks and stones at him under Snaptrap's order. They both appeared to be friendly to Larry after they joined him, though.
Ollie was nicer to Keswick than any of the T.U.F.F. agents in Snapnapped, but they still seem to be at odds with each other afterwards.
Dudley, Kitty and The Chief
He views all of them as enemies more than Keswick, although he doesn't appear to resent them as much as the rest of his friends at D.O.O.M.
