Gamzee Makara

TerminallyCapricious is one of the Trolls introduced in Act 5. He/she has only recently made an appearance in the comic. His/her associated zodiac sign is Capricorn. TC apparently sees Karkat as his/her best friend, despite a strained relationship from CG's end. He/she appears to be a juggalo, as his/her text is littered with references to the band Insane Clown Posse.

He/She appears to have a dark purple text color, and types with each letter alternating case, which seems to annoy Karkat. Vague allusions to his/her strange horns have been made, but they haven't been shown yet.

He/She speaks an awful lot like Dave especially with his propensity for swearing.

"Capricious" means impulsive and/or unpredictable, so this may be an indicator of his/her personality. He/She doesn't like knowing the technology or science behind things, stating that it "steals up all the fuckin' magic out of [his/her] miracles".
