Dynamo

Jei Akiyama, is a young Pokemon trainer and the main protagonist of Pokemon: Middle Ground.

History
Dynamo and Gryffon Fukui were in Santalune Forest when they found an injured Chespin. Gryffon believed that the Chespin should be left behind behind because it may be dying, but Dynamo wanted to help the Chespin. He took the Pokemon to Kingsley, an elder in Rosea, the boys' hometown. The man rubbed the Chespin with a special salve to help his wounds heal faster. Dynamo then took Chespin home to let him rest. Soon after, the two became close friends.
