A combination of Meowth's sprites from Red/Blue and Black/White.

The Red/Blue sprite is probably my favorite Meowth sprite in the entire series, but the lower half of it looks a bit off (it is a Gen 1 sprite, after all). I combined it with a better looking body and tweaked it quite a bit (most notably the colors and the raised arm) and the result is this.

(For those who follow me for my more typical stuff, this was part of the process, but I thought it was worth sharing on its own.)
