Grim

(Voiced by Greg eagles) he was known as the world's infamous grim reaper of souls. Untill billy and mandy beat him at a limbo contest.

he is the father of princess twilight sparkle. And soon to be father in law of kyle Akers. Grim was an overprotective father when he met kyle. And sure they wouldn't get along like most boyfriends who try to get along with their girlfriend's dad do, but grim soon learn to trust him after their last adventure in twilight, kyle, billy and Mandy's big boogey adventure. Another reason why grim didn't trust kyle much cause his uncle was his old school bully boogey (billy and mandy) but afterwords. They were cool with each other. And even became good friends. Who knows. He will even be a grand father one day.
