Eternatus

Game data

Eternatus sits here because the games give it a base Speed of 130. 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 130 for Eternatus. None of them timed an animal.

2. The giant of the story

   Eternatus is the towering poison-dragon at the center of that generation's plot, and the games give the usable form a high base Speed. Eternamax, the story encounter a player does not keep, is left off this list.

3. One species block

   Eternatus has one main base Speed. A Mega, a regional form or a fusion is a different row when the games publish a different integer.

Nearby on the base Speed list: Eiscue (Noice Face) and Mega Gengar. Same kind of stat. Different lore.
