“And why does this new girl look so much like Mario?”
So, even though Pokémon HeartGold and SoulSilver are old news by now, I’ll still give a hack based on them.
It’s the new female playable character from HG/SS, Lyra/Kotone.
Based of BigSharkZ’s Peach with Mario’s cloth (and I did of course ask him for permission).
You can consider this a “filler hack” since, I don’t really have something major to work on at the moment.
