This should be fun. -^_^-
Here is a version using Kirby's Hats for ALL of his attacks:
__________________________________________
Basic Attacks
Jab Combo
Sword Kirby
First
2%
Slashes with sword.
Second
2%
Slashes with sword the other direction.
Third
2% + 1%
Stabs with sword. If Kirby has 0% damage, he unleashes a sword-shaped energy shot that acts like a 1% projectile going twice his jab range.
Dash Attack
Wheel Kirby 8%
As seen with Jigglypuff, except Kirby looks like a Wheel.
__________________________________________
Aerial Attacks
N-air
Spark Kirby 12%
Same as his Twinkle Star, but instead of spinning Kirby hits all around him with electricity. Zap!
F-air
Burning Kirby
12%
An aerial fireball dash that knocks opponents up and away. If you're played Kirby games, you know what I'm talking about.
D-air
Stone Kirby
10%
Look out below! Kirby drops on people's heads while in one of various stone forms. The hit is similar to Zero Suit Samus' d-air. Meteor Smash!!!
U-air
Spike Kirby
10%
Large spikes jut suddenly out of Kirby's back and poke at the enemy from below! Juggles vertically for combos.
B-air
Jet Kirby

Blasts a hot plume of exhaust behind Kirby, knocking the opponents away. Same as his current b-air, but with a cute jet-shaped hat.
__________________________________________
Tilt Attacks
F-tilt
Beam Kirby
10%
Knock opponents away with a beam whip.
D-tilt
Fighter Kirby
8%
Sweep Kick. Slides on the ground, feet first and bowls opponents over.
U-tilt
Yo-Yo Kirby
8%
Arcs a yo-yo over head and knocks any opponent he hits into the air.
__________________________________________
Smash Attacks
F-smash
Mike Kirby
15% + Charge
This attack changes depending on how long you charge the Smash attack. Without a charge, Kirby will pull out a megahorn and blast anyone in front of him with a loud shout. If charged slightly, Kirby will pull out a small microphone to ampliphy his voice. If fully charged, Kirby will use a standing stage microphone and will sing very loudly blasting anyone in front of him with a terrible screech. (other than this, acts like his same F-smash).
D-smash
Mirror Kirby
14% + Charge
Kirby will split into two images of himself and hit to both sides at the same time!
U-smash
Fighter Kirby
15% + Charge
Rising Break! Kirby does an uppercut so powerful, it splits the very air around him with the impact! Not as strong as Knuckle Joe's, but impressive none the less.
__________________________________________
Special Attacks
Neutral Special
Inhale
Copies opponents or spits them out! Drop off the stage to Kirbycide. Swallow items (but this time you can spit them back out as stars!)
F-Special
Cutter Kirby
5%
Tosses a blade to the side which spins around and comes back. Hop over it to keep it spinning past you.

__________________________________________
Final Smash
Crash Kirby
18%
Kirby floats into the air and begins to emit a huge aura of power! There's a huge crash and Kirbys fly around the screen at amazing speed and striking everyone at once. The only way to avoid this is to Roll or Sidestep at the right time. This attack automatically breaks any shield.
