Marco

Marco is a recurring character in Pokémon Inferno.

Later in the game, you find his lab on Route 12.

Much later, you find his old lab in the edge of the region.

He is the eighth gym leader you fight in the game, and gives out the Spider Badge and TM13 Ice Beam upon defeat.

Personality
He is a lazy scientist, and likes making puns, but he doesn't do it often. He doesn't do science often either, and just wanders around, looking for something to actually research. Due to his laziness, he frequently delays his gym battles, much to the dismay of his challengers.
