Tibbers is a shadow bear, a ferocious denizen of the petrified forests in the Voodoo Lands.
Just outside the forest, a shadow bear would terrorize the Gray Order colony, a group of Noxian outcasts who chose to reside in the Voodoo Lands to live in peace.
He was later tamed by Annie The Dark Child (League of Legends), turning him into her pet. To this day Tibbers remains by her side, spellbound as a stuffed doll to be carried like a child's toy. When Annie uses her ultimate, Tibbers is released, dealing an AoE nuke. He then remains for 45 seconds, and deals continuous damage to enemies around him, can be controlled and can attack enemies.
So far, three skins affect Tibbers's appearance: Annie in Wonderland, Prom Queen Annie and Frostfire Annie.
