Trevor

Trevor is Tierno's best friend and the two cannot be more different when placed side by side. Trevor is exceptionally short for his age, while Tierno maintains a rather large physique. Trevor is also soft-spoken at times, whereas Tierno is usually loud than not. Alone, Trevor is often seen researching or exploring the outdoors as a hobbyist photographer.

Trevor was first introduced in Pokémon X and Pokémon Y versions.
