Which Pokemon weigh less or the same when they evolve

pokemon-series

Most Pokemon gain weight (and height) when they evolve. There are some exceptions to this, for example Gloom to Bellossom, and Cosmeom to either Solgaleo or Lunala. Which Pokemon lose weight or retain their weight when evolving?

There are some lists online, but they are all incomplete.

Best Answer

Pokemon that lose weight:

  • Gloom (29 lbs / 8.6 kg) → Bellossom (12.8 lbs / 5.8 kg)
  • Porygon (80.5 lbs. / 36.5 kg) → Porygon2 (71.6 lbs. / 32.5 kg)
  • Shelgon (243.6 lbs. / 110.5 kg ) → Salamence (226.2 lbs. / 102.6 kg) (Thanks to Sumurai8 & MBorg)
  • Nincada (12.1 lbs. / 5.5 kg) → Shedninja (2.6 lbs. / 1.2 kg)

Pokemon that lose height:

  • Gloom (2'7" / 80cm) to Bellossom (1'4" / 40cm)
  • Dragonair (13'01" / 4m long) → Dragonite (7'03" / 2.2m tall)
  • Porygon (2'07" / 80cm) → Porygon2 (2'00" / 60cm)
  • Haunter (5'03" / 1.6 m) → Gengar (4'11" / 1.5 m)

Notes

  • Gengar (89.3 lbs. / 40.5 kg ) weighs more than Haunter (0.2 lbs. / 0.1 kg) (Thanks MBorg)
  • Porygon2 gains some of the weight back for Porygon Z.
  • Nincada to Shedninja loses about 10 lbs, but there are extenuating circumstances.
  • This list is most likely incomplete: please edit if you know others
