Trivia

• In Diamond, Pearl, and Platinum, HM05 has the item sprite of a Template:Type2 HM, even though Defog is a Template:Type2 move. It is possible that this is because Defog's HeartGold and SoulSilver counterpart, Whirlpool, is a Water-type move.
• HM05 is the only HM and only machine move so far that has changed moves within a generation, from Defog in Diamond, Pearl, and Platinum to Whirlpool in HeartGold and SoulSilver.
• HM05 has contained the most different moves of any HM, teaching four different moves throughout the series. Due to its changing moves mid-generation as mentioned above, it is also the only machine that has contained four different moves (the maximum possible) that contained the same move for more than one generation.
  • Interestingly, two of the moves it has contained are the two HM moves which first appeared as HMs in Generation II.
