do you have any futa headcannons about any of the Pokemon girls?

personally I like the idea of Gloria having a huge cock and loving to dom soft feminine boys

Headcanon. Canon. A cannon is a weapon.

Inspired by that one Derpixon animation, Hilda is def a futa.

Along those same lines, but not a Pokemon girl per se, Ditto would always transform into a futa version of any girl transforms into. Ditto always transforms into an exact duplicate of whatever it's looking at, but we know it's used for breeding too. So, if it looks at any Pokemon Trainer girl, clearly it would also add a nice cock to her.
