I think technically in the lore of the Pokémon universe victini always wins because there are the victory Pokémon
And if I remember correctly, I think the idea for victini is that she will fight the MC on the ship she wins leaves. They have a second go at it, but the MC tries his best to make her horny so she being fucked by him is her victory.
Well, that’s the original plan for her I don’t know how it changed over time, but I think that’s it
