Karkat is gruff, foul mouthed but efficient when it comes to being Terezi's right hand troll. He has some respect for Terezi but won't hesitate to call her out on her crap. He is probably the only one who could argue with Terezi and stay alive. However, he's rather soft hearted and a tad righteous when it comes down to things. He's squeamish about blood, specially when it comes to his own.

His voice should be guarded, rather scratchy considering he yells a lot, and maybe mildly irritated. When angry, pour all your anger into it.

NOTE: Karkat may be voiced by a male or female actor so long as he still sounds like a young teenage male.
