Sloman "Slo Mo" Mortavitch (formerly Moe "Slow Moe" Deadovitch) is a 2010-introduced and all-around character. He is a zombie and a student at Monster High. Specifically, he is the student disembodied president, which is an interesting position to have for someone whose biggest challenge throughout the day is making decisions and who cannot improvise speeches. On the other hand, Slo Mo might be slow, but he is also thorough, a team player, and one of the smartest students at Monster High. He is best friends with Ghoulia Yelps and Deuce Gorgon.
His vocal effects are provided by Audu Paden in English.
Slo Mo is a fairly decent natured fellow, with a reserved sense of humor. At one point he gives Frankie a thumbs-up when she asks him about the new "Sugar Eyeballs" from the school vending machine, implying he shares Ghoulia's love of junk food.
Generally though, he's the zombie archetype. He simply stands there staring blankly into space like a regular zombie, shambles about, and moans and groans on occasion. His eyes also tend to roll in different directions.
Most often static, he has shown distress over being forced to impersonate Lagoona's aunt and annoyance at Frankie, Clawdeen, and Draculaura for interfering with his chess match. He also possesses a low tolerance for bad music, as he destroys Heath Burn's guitar on two seperate occasions when Heath attempts to sing.
Slo Mo wears a Varsity letter jacket in the school colors, showing that he's a member of at least one Varsity club. He hasn't been shown to play on any of the sports teams onscreen as yet. Ghoulia mentions a tall zombie boy on the casketball team in her diary, which seems to most likely be him. A picture of him is also shown next to a casketball trophy in "Cyrano de Ghoulia"; there is a degree of irony to be found in a zombie playing casketball, as zombies aren't known for speed and agility.
Slo Mo is likely to be on the Varsity Chess Club as well. He is shown to represent Monster High in a City Championship Chess Match, implying he's not just a dumb jock stereotype. He has the most on-screen appearances of all the non-toy characters. He is a nerd and an easy target for bullies like all zombies in Monster High.
Slo Mo is the son of the zombies.
Slo Mo is friends with Gil and Heath Burns; Gil even acts as his "wing-man" on one occasion, as in Date of the Dead. Save for two occasions where he destroys Heath's guitar after a particularly horrid attempt to sing, Slo Mo doesn't seem to have much of an issue with Heath's antics. Slo Mo's best friend is Don of the Dead, another zombie with whom he has a rivalry over Ghoulia's affection. However, this doesn't stop the two from hanging out together a lot. In "Freaky Fridate" he is shown to be on good terms with Deuce.
Ghoulia Yelps has a crush on him and Slo Mo reciprocates the feelings, smiling in her presence and holding hands with her. He even lets slide her poking him in the eye, in Cyrano de Ghoulia. During The Bermuda Love Triangle, he gets into a fight with his friend Don over Ghoulia. The outcome is unknown, but in "Monster Mashionals Part 2", he is shown being still Ghoulia's main interest.
