Sergej Velikjako

Sergej Velikjako is a major character in ''How to Survive High School. ''Sergej is a student who transferred over from somewhere in the Balkans, specifically one of the countries in the former Ygoslavia, presumably Bosnia but also, possibly, a fictional country. The customs of this country are made up, although both Sergej's name and the language he usually speaks in are Bosnian. Sergej is a huge, tough kid who doesn't speak or understand much English.

Personality
Sergej is very friendly and usually open to talk. His poor English often causes him to call people by whatever he sees them as, making his opinions of others very transparent.

Appearance
Sergej is tall and stocky. His nose is big and has a bump on it, and he has a huge, shaggy mop of black hair, brown eyes, and olive skin. He also appears to have an excessive amount of body hair, more than any other character. He usually wears a black track suit with sneakers and a white tank top.

Trivia

 * Throughout the series, Sergej usually speaks Bosnian, but on a few occasions has spoken Bulgarian, Romanian, and made-up gibberish. It's most likely that his country of origin is either Bosnia or else a fictional country, since its customs and "marriage traditions" are entirely fictional.
 * His surname is a combination of the Bosnian words "velik," which means "big," and "jako," which means "strong."
 * "Sergej" is the Bosnian spelling for the Russian name "Sergei" (Sergio in Spanish). There is no English variant of this name.
 * He owns a goat named Miljenik, which is Bosnian for "darling."
 * He appears to have an obsession with goats.
 * Judging by his appearance and personality, he is from the poorer part of the former Yugoslavia, and probably from a rural village.
