This is the mascot for Zorua from the "Transform! Ditto" series.
 
This is the challenge story of Ditto, who is not good at the "Transform" move.
Ditto tries its best to transform into other Pokémon, but its face remains that of Ditto, and this has been turned into a mascot!

You might be able to understand how Ditto feels about being bad at "Transform"!
