>>35808869I've always been sucker for the guardian-angel aspect that you mentioned. It truly shows what loyalty between a Trainer and a Pokémon would be like.
The design, grace, Dex-entry, looks, behavior, everything that the Gardevoir wields is perfect and deserves to be loved.
About the last assumption you made, no, I wouldn't straight-up fuck a Gardevoir.
I would rather hold hands with her, hug her and tell her how much I love her. If she returns my feelings and tell me that she does indeed want to make love with me, then and only then would I 'fuck' her.
