>>47098086Reminder to everyone that Lopunny is an intentionally lewd design.
Being based on bunny girl costumes, it comes with Cute Charm, Klutz, and Limber as it's three abilities, a nudge at general ditzy bimbo behavior perhaps though it still does come at a 50/50 gender ratio.
It evolves from friendship, and it's the only Pokemon to ever learn Frustration and Return naturally which gives the move special meaning to this Pokemon.
Lopunny learns Return by level 13(or on evo in gen 7) whereas Buneary learns Frustration at level 13.
By level 13 this means the Pokemon is grateful for evolving into a Lopunny and would like to return it's appreciation for the trainer. If it's still a Buneary by level 13 then it learns Frustration, meaning it is frustrated with it's trainer because it hasn't evolved yet.
Rabbits in real life are very affectionate and also horny creatures and it's designers went onto do things such as giving Lopunny a cry ingame that sounds similar to that of a cat whistle or cat call and it conveniently made it's debut in the gen that mentions marriage between humans and Pokemon in the past.
Another fun little quip is that Flint is the fire-type specialist though he has a Lopunny on his team, perhaps a pun calling Lopunny hot.
They knew exactly what they were doing with this design.
