Ooh, is it time for a Gardevoir moveset?
The way I see it, she should have about the weight, size and moving speed as Mewtwo does now, which will be no problem if they fix him ( making the big guy lightweight just makes NO sense ). But on the other hand, she should have a great horizontal moving speed in the air, like Jigglypuff. The first jump is very low, but the second jump makes her rise and float as if she had summoned wind to carry her aloft.
According to various sources, Gardevoir can distort dimensions and has empathic abilities, plus, she's a guardian... that can be worked with.
A: It does a move like Mewtwo's Disable and a brief distortion in the air flings opponents back a little. Used to keep them off her face.
>A: Like A, but she moves her hands around forming a swirl that briefly sucks an opponent in and then spits them out, kinda like Pichu's or Zelda's smashes, but weaker.
^A: She goes into a praying pose bowing down a little and energy appears above her head; very many little hitboxes, low damage and knockback, but very good range - used for defense against aerials.
vA: A more-or-less kneeling attack where she does a blocking motion with her hands - about the same effect as Yoshi's down+A, set knockback.
Her smashes are meant to look like dances.
>Smash: She does a sort of half-spin, then looks away from the direction she faces and thrusts out her hand as if to forbid someone to get closer. A flash of light deals little damage for a smash, but explosive knockback. Very slow startup and cooldown.
^Smash: A very low and slow kneeling dance move ( dying swan? ), her hand draws a circular motion upwards along with her head. Flash of light again, same as before.
vSmash: Faster than the others, she does pirhouettes that first deal a little damage caused by little particles of light that look like leaves, then a stronger blast sends the opponent(s) off at about the strength of Jiggly's down-smash.
Don't feel like thinking up aerials right now, I'll add some if there's interest.
B - Destiny Bond: If Gardevoir is defeated while using this move, the responsible opponent receives 30%.
^B - Teleport: Teleport.
>B - Future Sight: Gardevoir glows and sees into the future. If she isn't hit within the next 4 seconds, all opponents receive 10-15%.
vB - Synchronize: If Gardevoir is hit by a B button move while this move is in effect, the opponent receives the same damage as Gardevoir. Damage is not blocked and no knockback is dealt to the attacker. Almost as quick as the Shine.
Note sure about the B moves, there are probably better choices.
