Since "Mega Lopunny" have an "X" on her forehead i tried making a "Mega Lopunny" with an "Y".
Mega Lopunny Y is a dancer pokémon, it produces paint from the tip of it's ears that change colors according to it's mood. It dances gracefully painting all around knowing that any mistake while dancing may cause it's own fur to be painted as well, when it fails to dance perfectly it's paint becomes black.
