Ash first encountered his Gible when he met Old Lady Wilma, a woman who teaches Dragon Pokémon the special move Draco Meteor. Ash assisted Gible in the learning of the move and Gible decided to follow Ash. It also has the habit of biting onto heads. Later on, Ash noticed Gible followed him and eventually captured it. It has many powerful attacks such as Draco Meteor, Dig and Dragon Pulse.
He has been in quite a lot as Piplup seems to get hit by the failed Draco Meteor. In that episode Gible battled Barry's Empoleon and lost easily.
Gible has been appearing in the two following episodes DP158 and DP159, when Gible once again hit Piplup with Draco Meteor and chewed on rocks and sunk in the water and had to be saved by Ash's Buizel.
Gible wasn't seen again until DP164 where it expanded Piplup's couch gag which made Piplup learn Hydro Pump and run away.
