Deoxys

Game data

Deoxys sits here because the games give its Normal Forme a base Speed of 150. That integer is a battle stat. The explanation is game lore, not a running speed.

1. A stat, not a stopwatch

   Base Speed is the number a battle uses before natures, items and stages. PokéAPI, Bulbapedia and Serebii agree on 150 for Deoxys. None of them timed an animal.

2. The Normal Forme

   Normal Forme Deoxys is the balanced alien stat block, and it is already high in Speed before the other formes specialize. The games treat each forme as its own set of base stats.

3. Normal Forme

   Deoxys is Deoxys's Normal Forme. The games publish a separate stat block, so it is not folded into the base form.

Nearby on the base Speed list: Deoxys (Attack Forme) and Electrode. Same kind of stat. Different lore.
