Brett seems to be a rather laid back person. He does not seem to mind the frantic nature of the Greens and their antics. As a matter of fact, he seems to be all together supportive of whatever endeavor they have. He is a very sociable person as in "Blood Moon", he threw a Halloween party at his apartment. He was delighted to see that the Greens had shown up, implying that he may have intended for them to appear.
Brett is a large obese man with green skin. His hair is depicted as short soft dreadlocks that stick up and a beard. He has earrings, and a plain brownish white shirt. He wears an unusual brown, orange and red man skirt and sandals. On his left hand he has a small string bracelet.
- While the two have not shown any interaction yet, Brett might be friends with Gloria based on the fact that she knew where his party was.
- He bears a slight resemblance to Wasabi from Big Hero 6.
- A line was cut from an episode revealing that his dogs were named Chunks and Chunks Jr.
