Ephraim is a character of the day who appeared in The Grass Route (EP180).

He is the son of a couple of farmers who live in a small town close to Ecruteak City. He specializes in raising Grass-type Pokémon, mainly because his parents use a large collection of Grass-type Pokémon to maintain their farm of flowers. He convinced Ash to enter his Bulbasaur in the Grass Tournament, held near where he lives.

Ash faced Ephraim in the finals of the tournament, with Ephraim using Skiploom. Skiploom almost lost, but learned Solar Beam at the last moment. It defeated Bulbasaur, and won the tournament. Ephraim's prize was a collection of Leaf Stones, which he planned on using to evolve his parents' Pokémon.
