Do Pokemon forget a move when changing form?

Solution 1:

Except for Rotom and Kyurem, all Pokémon keep their moves when changing form. The form-exclusive moves are the following:

  • Fan Rotom's Air Slash
  • Frost Rotom's Blizzard
  • Heat Rotom's Overheat
  • Mow Rotom's Leaf Storm
  • Wash Rotom's Hydro Pump
  • Kyurem's Glaciate and Scary Face
  • White Kyurem's Fusion Flare and Ice Burn
  • Black Kyurem's Fusion Bolt and Freeze Shock

Confined Hoopa can know Hyperspace Hole, but it will not be able to use it in battle.
