Expanded my moveset. It's still a work in progress.
Standard special move: Hammer (alt: Cudge, Hammer Throw); simply damages, but can be charged to do more damage. Cudge is slightly smaller, does less knockback, cannot be charged, and deals more damage. Hammer Throw works similarly to Yoshi's Egg Throw. Does more damage and less knockback.
Up special move: Parakarry (alt: Yoshi); Parakarry lifts Paper Mario up slightly, and carries him horizontally in the direction Paper Mario is facing. Yoshi only carries him horizontally, but goes slightly farther.
Down special move: Bombette (alt: Bobbery, Boomer); Paper Mario sets down Bombette, who walks in the direction Paper Mario was facing. Initiating the move while Bombette is already out causes her to explode. Does about the same amount of damage as Link's bomb. Bobbery can be held as long as down and B are held, and does slightly more knockback, but slightly less damage. Boomer does more damage, but cannot move or be held.
Side special move: Kooper (alt: Koops); Paper Mario jumps on Kooper's shell, and kicks him forward. Koops can be held and long as left/right and B are held. Koops can go through multiple enemies.
Final Smash: Earth Tremor; Paper Mario jumps on the Bronze Star, and is invincible. The screen shakes, and after about five seconds, about 30% of damage is dealt, and high knockback is dealt.
