Neutral: Spear Throw. Bandana Dee tosses one spear. Charge the move to throw three at once. 8% per spear. Middle/single spear can pin foes
Side: Parasol Drill. Bandana Dee rushes forward a short distance with his parasol. Can be held for Parasol Shield, blocking most projectiles. Individual hits, 2%. Finisher hit, 5%. Parasol Shield: 2% per hit, no finisher. If held in midair, can slow your descent and protect you slightly from attacks above, but doing this prevent you from using Spearcopter.
Down: Two-ton Punch. When used on the ground, hold button to charge up. When used in the air, the distance you fall determines its power. Can Meteor Smash if you land directly on foes from midair, which will cancel the move, but if you miss, you can't cancel. Bandana Dee punches the ground with great force, causing stars to appear on either side of him with a small shockwave that extends slightly further than the stars. Uncharged/low to ground, 3%, no stars (but can trip). half charged/further from the ground, 10% per star, 6% from shockwave. Fully charged/very high, 16% per star, 12% from shockwave.
Up: Spearcopter. A chargeable recovery move like Diddy's Rocketbarrel Jetpack, Bandana Dee spins his spear above his head very quickly. A fully-controllable recovery like Villager's balloons. When your time runs out, Bandana Dee will twirl slower and begin falling, not as fast as normal, but not as slow as Peach with her own parasol. Deals 1.5% damage per hit.
Other Attacks:
Getting up: Jabs his spear forward, then kicks backward. First hit, 5%, second hit, 3%
Ledge attack: A quick spear poke. 3%.
Final Smash: Megaton Punch.
Bandana Dee charges forward a set distance, capturing all foes he hits in a cinematic attack. Re-enacting the Megaton Punch minigame, foes are forced to stand right next to Bandana Dee's platform as he performs flawlessly in the minigame, cracking Popstar and sending all foes flying. (FS Meter version could have Bandana Dee re-enact his performance in the actual games as a visual illustration of the FS Meter resulting in weaker Final Smashes).
Note: I went with this version of the Final Smash because there's not much else that fits Bandana Dee's character, and concerning how it actually works, while I want to have it be an actual gameplay re-enactment of Megaton Punch, where YOU have to press the button with the right timing, I'm not sure how well that works in practice given Ultimate's "streamlined" Final Smashes, and without making it encompass the entire stage in a one-hit KO, I'm not sure how it could work any other way on stages like Palutena's Temple or New Pork City.

Victory Animations:
