女体化 ポケモン
ポケモン means pokémon and 女体化 means someting like female version (correct me if i'm wrong.
Instead of 女体化 you can also use 性転換 that I think it translates into gender bender.
Also, instead of pokémon you can use the japanase name of the character, that you can find in any wiki.
I know there are some that are from twitter, but I don't know how to find them there.
