Tyrant

Tyrant is Merlin's pet giant and one of the 2 tritagonists of Season 1 and a minor protagonist for the rest of the series.

Personality
Tyrant is not a very bright creature. His solution to almost every problem is to smash it with a club. He is still very loyal to his master, Merlin (Who he towers over). He also likes having the Eleventh Doctor around for company.

He also has a bit of a family tradition where he eats what's left of his enemies' corpses.

Weapons
Tyrant's favorite weapons are his trusty club and a sharp rock which he uses to impale his enemies. He also likes to throw it at his enemies when they're too far away to strike with his club.
