This Teddiursa is a Normal-type Pokémon created by the Unown for Molly to battle Brock.
Biography[]
Teen Molly used a dreamed up version of Teddiursa to battle against Brock's Vulpix. After a long battle, Teddiursa then defeated Vulpix.
In the end credits, Molly is shown owning a real Teddiursa. How she acquired this Pokémon is unknown, but it is not unreasonable to assume that it was captured by her father while he was on his research expedition for the Unown and was given to her to be a playmate.
