This post gave me an idea...
Create a Pokémon newcomer and name their Specials. I'll start.
Since I see people doing it, and I've done one in the past:
Gallade
U-special - Aerial Ace: A quick upwards slice in the air, similar to Simon and Richter's uppercut. Great for off the top KOs, and has decent vertical and horizontal distance due to the ability to angle the direction, but Gallade is left vulnerable if he misses.
N-special - Psycho Cut: A far-reaching horizontal slash in front of Gallade. However, it can be charged as well, and damages opponents who get too close to him. It KOs fairly easily when fully charged (think of Marth's Shield Breaker, for instance) and can still keep opponents away at low percent, but has a bit of endlag in order to prevent spamming.
S-special - Night Slash: A slash with a dark effect added to it. Has a unique critical hit effect, in which it has almost enough launch power to one-hit KO, but has a 1-in-20 chance of happening. Quicker than Psycho Cut, but slightly weaker otherwise.
D-special - Swords Dance: Gallade hold out his hands above his head, and does a chant to summon a clanking group of swords (later SD animation reference). Raises damage values by 20% for 12 seconds. However, charging takes three seconds, and it must be uninterrupted, or the Swords Dance only raises damage values by 5%.
