Caveman

Quagsire, also known as "Caveman" or Swagsire, is a Pokemon that Alice caught as a Wooper on Route 25.

He has a Timid nature, and Intimidate as an ability.

Name
Quagsire's fan-nickname, Caveman, is derived from when he had Bone Club as an attack when he was first caught as a Wooper. Other names using the same logic are "Cavemon" and "Cavesire."

Personality/Lore
Some view Caveman's deposit into the PC as him being "frozen" in order to make room for Karl Marcs the Mew. It is also theorized that the Wooper Bugsy possessed in Randomized HeartGold were also prehistoric.

Trivia

 * As a Wooper, he had Pure Power as an ability.
