He has three cyan freckles dotted on both of his cheeks underneath his eyes.His hair is a dark royal blue, with blue-grey streaks and cyan dots running through it, styled short and swept back. He has pointed cyan teeth and his mouth curls at the sides when he grins.He has cyan sclera with coral pink irises, and his eyelids are a dark royal blue. Baxter wears goggles; the frames are coral pink and the lenses are mid-yellow. Baxter also wears a full-length greenish-grey laboratory suit; it has mid-yellow buttons down the length of it.He has an esca on top of his head. The "light" is a yellow gradient, and there are two cyan stripes above it. He wears black rubber gloves and black boots. Personality: Baxter was originally anti-social and cruel, having checked in to the Hazbin Hotel just to prove redemption was impossible.When it comes to conducting experiments, he becomes uncomfortable when interrupted. With an eccentric character, Baxter prides himself on being a scientist, often calling himself a "mad scientist", and shows anger when his occupation is denigrated, most notably when he is compared to his former partner Sir Pentious.Baxter is fascinated by his mad experiments, no matter how dangerous and cruel they may be, with the goal of being respected in Hell. He reveals a more sadistic and apathetic side when experimenting with the Egg Boiz, risking the lives of his creations, which triggered the ending of his association with Sir Pentious. He mocks Cherri Bomb when she remembers Sir Pentious, ridiculing him for his apparent death.Over time, Baxter has slightly changed his taste for isolation and has opened up to other Hotel residents, such as Niffty and Husk, the latter from whom he is interested in learning new ways to call people "stupid", as well as developing a taste for redemption activities such as therapy.Baxter feels genuine affection and concern for his loved ones, such as his bond with Niffty, playfully supporting her when they spend time together, and also calling Vaggie his "best friend". Thus, like Sir Pentious, the Hotel's positive influence has rubbed off on him.
