I made a moveset for Ridley, it may work:
Knockoff Percentage: 175%
Normal:
A: Claw/Bite. Claw: 7–10% Bite: 8–12%
A Standard Air: Aerial Claw. 7–10%
A Side: Lunge. 8%
A Front Air: Glide.
A Back Air: Aerial Smack Down. 11%
A Smash Side: Wing Slash. 12%
A Up: Tail Jab. 10–14%
A Up Air: Air Spin. 5% every second for 5 seconds
A Smash Up: Claw Uppercut. 10%
A Down: Tail Swipe. 10%
A Down Air: Body Smash. 10%
A Smash Down: Ground Shockwave. 12%
A Dash: Charge. 14%
Special:
B: Fireballs (fires 4 fireballs and charges up to fire 2 bigger ones that do twice the damage.) Small: 15% Big: 20%
B Side: Fire Stream (causes Ridley to make a stream of fire that does a lot of damage for 10 seconds.) 5% every second
B Up: Whirl Wind (this makes him flap his wings while in the air and causes opponents to fall off the arena.)
B Down: Tail Smash (this makes him spin his tail and crash it into the platform while in the air.) 15–30%
Combos:
Fire Bombs: A Side then B. This move is where Ridley glides across the screen and shoots fireballs down below and it can be charged for 2 bigger ones. Small: 15% Big: 20%
Aerial Fireballs: B Up then press B Multiple times. When Ridley is trying to blow everyone off, he will shoot fireballs while in the air, which move faster because of the wind that he is creating from his wings, this move can be used more than once while in the air and can be charged for 2 bigger ones. Small: 10% Big: 15%
Pogo Tail: Hold B Down and move the joystick up and down in half circles by turning it in the direction you want him to go to. This move is just like it is in Super Metroid and can be moved left and right. 15-30%
Fire Rain: A Side then B Side. This move is where Ridley glides across the arena and breathes fire on the players below and does not a lot of damage, but lasts for 10 seconds. 5% every second
Final Smash: Meta Ridley
This turns Ridley into Meta Ridley, this makes him bigger, disables his combos, special and normal attacks do double damage, invincibility and most of his specials are replaced with stronger moves.
Plasma Beam: Press B. Shoots a huge orange beam that does 1% of damage every 0.5 seconds for whoever touches it for 30 seconds.
Missile Launcher: Up B. Shoots 5 homing missiles that do 40% of damage per missile. (only works in the air)
Laser Eyes: Side B. Shoots red lasers out of his eyes that do 30% of damage.
Note: Ridley is a slow character, so these movesets are set up for a slow character. Also, this is for the wii remote and nunchuck controls.
