Baxter is a short anglerfish sinner demon with blue-grey skin and with fish fins on the side of his head, which resemble ears, share the same color, and another fin on the back of his head with the same color scheme as his hair. 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.

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.

Immortality - As a sinner, Baxter is biologically immortal, being unable to die from illnesses and unable to age, remaining the same age as when he died, thus cannot die of old age and other natural causes. He also cannot die from any kind of damage to the body, and will recover from any injury, however, he can only be permanently killed with angelic weaponry.
Bioluminescence - Baxter has a lure, which means he can make his own natural light.
Skillset
Enhanced intellect - As a scientist, he possesses high intelligence, even joining the Hotel to conduct research. He is also keen to learn more, such as new ways to say "stupid" shown in "Silenced".
Inventing - Baxter is shown to be a good inventor, more centered around biological creations than technology itself.
Bio-engineering - He is experienced in biological engineering, creating living creatures such as the Egg Boiz, or even altering their biology and physiology. He even created a monster with a regeneration that could recover from the attacks of Zestial, the oldest living Overlord. His most noticeable creation is Vox's pet shark, Shok.wav, who the Overlord Alastor had trouble facing and fled from in "Curtain Call".
Technological expertise - Prior to the series, Baxter had created the entire security system for VoxTek, as revealed in "Weapon of Mass Distraction".
Hacking - As shown in "Curtain Call", Baxter can hack into different systems, and even disable them. He has showcased the ability to hack into VoxTek's servers, Velvette's phone to disrupt her powers, and Vox's own head to mute him.
