Pikachu with a not-gun.

Pikachu with a not gun is an image on the topic used as a joke. The image was originally created by Scratcher and cartoonist @johnelr. They originally made a side-facing Not-Gun, but a front-facing Not-Gun was later created and is the more popular of the two.

It can be seen as an emote, similar to Twitch's Pog or Kappa, as in an emote, not as in what they mean on Twitch.

A Grookey front-facing gun was created later, but it has not been used very much, if at all.

On January 17, 2021 M1mikyu has created a 3D model of a not gun.
