There are many Kanto HM slaves in FireRed & LeafGreen, but here are the best ones in both games.

  1. Espeon – This dragon-like Pokemon is a great HM slave because it can learn Dragon Pulse and Dragon Claw, two powerful moves that can take down most foes.
  2. Machamp – This massive powerhouse is a great HM slave because it can learn Machamp Slam and Machamp Fury, two powerful attacks that can take down even the strongest foes.
  3. Dragonite – This dragon-like Pokemon is another great HM slave because it can learn Dragon Rage and Dragon Claw, two powerful moves that can take down most foes quickly.
