Bulldoze

Bulldoze specialists — Onix, Makuhita, Hariyama and friends — reshape the world itself. They flatten hills, clear debris, and are specifically required to rebuild each of the region's Pokémon Centers as you restore them.

Later on, Bulldoze becomes your "undo button" for construction. Buy a Relocation Kit or Demolition Kit from the PC Shop (about 10 Life Coins each), drop it at the structure you want moved or removed, then bring a Bulldoze Pokémon over to finish the job.

Because they change terrain permanently, Bulldoze Pokémon are invaluable whenever you want to redesign a habitat or carve a new path through the landscape.
