Are there any Pokemon that get smaller when they evolve?

There are a few cases of Pokémon getting shorter when they evolve.

  • Haunter (1.6 m) into Gengar (1.5 m)
  • Porygon (0.8 m) into Porygon2 (0.6 m)
  • Dragonair (4.0 m) into Dragonite (2.2 m)
  • Gloom (0.8 m) into Bellossom (0.4 m)
  • Cosmog (0.2 m) into Cosmoem (0.1 m)

Evolution reduces Kadabra's mass from 56.5 kg to 48.0 kg. Mega Alakazam is the same mass, but is shorter than Kadabra (1.2 m vs. 1.3 m; "base" Alakazam is 1.5 m).
