Jet

Jet is a determined soul. He's very quiet, a gentle giant as some may say. He isn't particularly intelligent, but he does his absolute best. He's from the deepest depths of the ocean, so when Kyogre ends up being summoned (Sapphire/Emerald, Alpha Sapphire), his home is tossed into disarray. This makes him anxious.

Jet's first appearance in any writing was in Pokemon: Deep Sea Monstrosity, where he had swam to the surface in Route 128 to try to help anyone who may have been tossed into the raging seas by Kyogre's awakening. His kind nature was shown first when he went out of his way to help a Vaporeon who was struggling to stay afloat.

Outside of PKMN:DSM, Jet has not appeared in any writing.
