Brock

Brock (known as Takeshi in Japanese) is a main character of the first Pokémon anime.

He only appears in the Ash lore once, in the background of a short outtake where he tries to woo Candela until Misty pushes him away and proceeds to hug Blanche. In the same strip, Ash and Spark are looking at a Pikachu-shaped phone charger.

It is unknown if either he, Brock, or Misty will appear in the actual comic.
