Sløth

Sløth is the lead vocalist and a guitarist for Belzebubs, as well as one of the band's founders.

Appearance
Sløth is quite average; he is taller than Obesyx and shorter than Hubbath and has a slight gut. He has black hair, parted in the middle, that reaches his shoulders and upper back. Like the other Belzebubs, and characters otherwise associated with black metal, he is always seen wearing corpse paint, even when sleeping.

Sløth is typically seen wearing a black graphic t-shirt, black arm bands or fingerless arm gloves, black jeans, and black sneakers, as does everyone else in the band.

Personality
Sløth has an affinity for dad jokes, puns (much to his family's dismay), and the occult. He has a tendency to describe mundane things (such as the Belzebubs' recording studio) in a vague, sometimes cryptic, manner, as if describing occult mythos.

He also seems to be interested in, if not infatuated with, Italian culture and can be seen speaking Italian to a waiter in one strip, likely as a form of courtesy. It is unknown whether or not he is actually Italian.

Hubbath
Sløth and Hubbath have known each other since the formation of Belzebubs in 2002, as they are both founders of the band. They are on good terms, with some comedic tension between themselves and Obesyx.

Obesyx
Obesyx and Sløth have also known each other since the band's inception, however Obesyx wouldn't join until later.

Samaël
Samaël, being the youngest and most recent recruit, doesn't have a very close relationship with Sløth. His addition to the band was by the suggestion of Lillith, his girlfriend, unbeknownst to Sløth, and Sløth's daughter. Nonetheless, they are on good terms, with Sløth also admiring his drum skills.

Sløth's Parents
Sløth's parents are rarely seen in the comic, only having appeared once, but is assumed he has a good relationship with them.

Lucyfer's Parents
Sløth isn't shown interacting with Lucyfer's, his wife's, parents very often, though it's also assumed his relationship with them is good. Sløth does has some apprehension towards Rose's, Lucyfer's mother's, habit of digging up rotting corpses and placing them in her house, interacting with them as if they were still alive.

Lucyfer
Lucyfer is Sløth's wife and the mother to his children.
