Corrine was born in Meltokio's Elemental Research Laboratory, though he hates the place due to the experiments performed on him in the quest for knowledge. Sheena often summons him to perform tasks she cannot do herself, such as distracting Noishe when necessary to subduing others. They also have a sense of camaraderie with each other.

Spoiler

The culmination of such a friendship comes when a lightning attack from Volt is aimed at Sheena in the Temple of Lightning. Corrine throws himself into the path of Volt's attack. Because of this, Sheena survives, but it is a lethal hit for Corrine. Corrine's death spurs Sheena on in their quest.
