The Underground Man in Pokémon Adventures

Pokémon Adventures

The Underground Man was first mentioned in A Conk on Cranidos's Cranium, spending time with Roark in the Underground. He makes his first appearance in Double Trouble with Dialga and Palkia I, where he and Byron were digging underground with the Explorer Kit to avoid Team Galactic from tracking the Sinnoh Gym Leaders. In the next chapter, he suffered the effects from the distortion of time and space caused by Dialga and Palkia battling. In Double Trouble with Dialga and Palkia VI, the Underground Man along with Byron, Professor Rowan, and Sir Berlitz reappear at the Spear Pillar and attempt to stop Charon from escaping.
