Hmm, I thought this was my studio. JK! Everywhere's my studio!
―Oskar Greason[src]

Oskar Greason is a student of Echo Creek Academy who, according to Principal Skeeves, has "a record". Star develops a crush on him in "Cheer Up, Star". As of "Starcrushed", Oskar is a high school dropout.


Oskar has brown hair that usually covers his green eyes. He wears a brown T-shirt, a red neckerchief, gray jeans that are torn at the bottom, and purple and white boots. He has two fangs on opposite sides of his upper mouth.

In "Girls' Day Out", he wears a blue T-shirt with the words "Wrestle Rama" printed on it. In "Starcrushed", it is shown that he has shortened his hair into an undercut hairstyle, making his eyes always visible.

In "Britta's Tacos", he wears a yellow hat and apron over his regular clothes, both with the restaurant's logo on it.


Oskar loves playing his keytar, typically on the hood of his car, but usually plays it discordantly; most who hear it scream and cover their ears. He has "a record", according to Principal Skeeves, and doesn't talk much.

He appears to hold some disdain towards his mother, judging by the lyrics of his songs in "Mewberty".

He mostly has a laid back, uninterested personality; After the Mewberty-form Star lifted him and his car up into the sky then dropped them back down, he showed no signs of trauma at all, even greeting Marco with a nonchalant "What's up?" In "Blood Moon Ball", his only reaction to Tom Lucitor's arrival at the school was to point out that his carriage was parked in a handicapped space.

In "Star on Wheels", Oskar treats everywhere he goes as his "studio", and he is revealed to be a horrendous driver who pays little attention to road safety. In addition, although he agrees to help Marco rescue Star, he is more concerned with having fun with Glossaryck, even suggesting that the two of them start a band together.

In "Starcrushed", he shows a genuine interest in hanging out with Star, stating that she always believed in him, and asking her about her magic. He also blushes when Star holds his hand during a failed attempt at a fist bump, and is happy at the thought of spending time with her over the coming summer.


In "Britta's Tacos", Oskar is shown working at the titular restaurant. When he and Star see each other again, he briefly notes that they had talked about spending the previous summer together, but quickly dismisses the thought.

In "Jannanigans", he is briefly seen serving Star, Marco, Tom and Janna their order. In "Mama Star", responding to strange noises, he goes under the restaurant and finds the group throwing garbage into the well that leads into the Realm of Magic (in hopes of drawing out the Firstborn). He then allows Star and the others to borrow his car for the trip into the realm.

In "Cleaved", Oskar is interviewed on television after the destruction of magic causes his place of employment to sink into the ground.
