Since I figure it's inevitable that they would be included, here's how I envision the characters from Cave Story.
Both should be ranged attack specialists. I see Quote being focused more on direct damage, while Curly's attacks are more defensive in nature. I didn't want the two to be clones, so I gave each one unique attacks.

Stats-
Quote's attacks are a little slow, but very powerful. They generally have great range. His defense and movement are unexceptional, although his booster gives him great vertical mobility.
Move List:
A - Polar Star - A quick ranged attack. Damage is high considering how quick the attack is. However, it does not stun opponents.
>A - Blade - A basic attack that does low damage, but has considerable knockback.
^A - Polar Star - Fired upwards.
vA - Rocket Launcher - Fires a rocket downwards at a 45 degree angle. Normally, it hits the ground immediately and explodes. Deals very high damage.
S - Spur - Similar to Samus's cannon in SSB, Spur can be charged up to deal great amounts of damage, and you can hold the charge while making other attacks.
>S - Spirit King - A phantasmal King charges forward a short distance, attacking all nearby enemies.
^S - Booster - Quote launches himself into the air with his jet pack. The flames damage those below.
vS - Fireball - Fires a slowly moving, bouncing ball of fire that deals high damage. Since it's affected by gravity, Fireballs can be used to attack enemies below you.

Curly is very similar to Quote. However, her attacks are a little less straightforward.
Tentative Movelist:
>A - Punch - A basic attack that does low damage, but has considerable knockback.
A - Machine Gun - Fired for as long as the button is held, in bursts of up to ten bullets. The damage is mediocre, but the bullets stun the enemy for a very short period of time. This attack has considerable recoil.
^A - Machine Gun - Fired upwards.
vA - Machine Gun - Fired downwards. Can be used to hover temporarily.
S - Bubbler - As long as the button is held, Curly summons bubbles which float around her. They damage (but don't stun) enemies they contact. The button can be pressed a second time to fire the bubbles forward.
>S - Snake - A fairly weak and slow missile that goes through walls.
^S - Tow Rope - Curly grabs ledges with a tow rope.
vS - Nemesis - The more badly Curly is injured, the more damage Nemesis deals. When Curly is on the brink of death, it is one of the most powerful attacks in the game.
