Most Pokemon get physically larger when they evolve. For example, the tiny Bulbasaur turns into the slightly larger Ivysaur, who then turns into the monstrous Venusaur.

Are there any Pokemon that instead become 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)

  • Just because I was curious, I ran a wikidata query to find all combinations based on data entered there. It finds Porygon, Dragonair and Gloom. w.wiki/pHr Wikidata believes Gengar to be 190.5 cm (no real source) and Cosmog has no height there, so is automatically excluded.

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).
