The Gatekeepers

The Gatekeepers were several Pikachu in Anniversary Red around Route 1 who constantly defeated Growlmander and Abe. At level 5, they only knew the attack Thundershock, which often resulted in paralysis and defeat early on.

One of the Gatekeepers returned at the end, being the final Pokémon of Professor Oak.

The Gatekeepers are depicted in artwork as being heavily muscled and mean spirited tough guys, such as bikers or martial artists.
