Semicolon is a 5'0" Filipino 12 year old who has an older sister that goes by "Colon".
He isn't *as* mentally unstable as his older sis, but has a creepier side to himself. (just know to run if he starts speaking Tagalog.)
He is in a group with colon and his other two best friends, Tilde (a British idiot) and Asterisk (a dominican idiot).
When he wants to be scary, he lets his mouth and eyes become black voids and lets some..black goop run down them (really freaky WAAAA)
