He appears as the first bosses in Sky Lagoon, he will chase the player with his claws and shots, you should note that it is possible to defeat Eregion in the first Sky Lagoon area. When attacking your claw hits the ground (stroke left or right hand when he raises his hand and attacks him), the player can damage the health of Eregon with Zero.

And then Eregon will returns as a boss of the area, and fight is too easy, and Eregon is defeated, Colonel will appears for the first time and this caused the Great Repliforce events.
