Well this is what I would consider an old fashioned PSA that I came up with for the Young Zelda Model by Black Boo. She has all of the same moves but many of them work differently to the same effect.

Her standard attack has an extra flame sweetspot at the end if you're close enough to her.
Side Tilt now hits multiple times.
Side Smash is a single lasting hitbox.
Up air is a multihitting explosion.
Side and Down aerials have weaker sweetspots but the normal hitboxes are stronger.

In general, her attacks are a bit weaker, she's a little faster, recovery is better but her weight is decreased a bit.

Any problems, let me know.
