Deoxys

Deoxys is a legendary pokémon who landed on earth from space along with his friend, a separate Deoxys. He is first introduced in Chapter 5 of Stun.

Deoxys is the third in line to mentor Stun, and is responsible for teaching him how to create solid clones using Double Team and giving him the ability to open a portal to the Distortion World.

Deoxys is known to live in Hoenn, but fled to Sinnoh, north of Snowpoint City, when the darkness possessed his friend. After the events in Stun, Deoxys traveled back to Hoenn with his friend where he lived a peaceful life away from humans and technology.

Some time between ''Stun III: Alola! and Project Stun'', Deoxys and his friend were captured by humans.
