Quote
--------------------
Gimmick
In Cave Story, weapons can become stronger by increasing your power meter. This is done by collecting orange energy crystals from defeated enemies. Taking damage however will decrease the meter.
For Smash, Quote's main gimmick would be his weapon power meter. There would be a single power meter that would increase either upon dealing damage to enemies or by taking damage (which ever would work best for balancing purposes). When the power meter is level 3, Quote's attacks would have improved properties such as additional damages and other unique features.
With that said, here is the moveset I came up with:
Normals
Jab: Polar Star
To mimic Cave Story’s 2D shooter playstyle, Quote’s jab would have him shooting from the Polar Star weapon similar to Mega Man’s jab.
Dash attack: King’s Blade
Quote runs and deals a slash attack with King’s sword.
Forward Tilt: Nemesis
Quote shoots with the Nemesis weapon. This is the only weapon in Cave Story that actually gets worse as it levels up, with the level 1 variant being a decently strong lightning beam while the level 3 variant just shoots out a bunch of weak ducks. I thought it’d be nice to keep this aspect as it’d stay true to the original game.
Up Tilt: Nemesis
Quote points upwards and shoots with the Nemesis weapon. Like his forward-tilt which also uses Nemesis, Quote’s up-tilt would become weaker and have less range as your power meter grows. Quote already gets a ton of crazy buffs when his power meter is high, so I thought it’d be balanced to weaken one of his defensive moves so he isn’t completely unstoppable.
Down Tilt: Fireball
Quote quickly shoots a Fireball towards the ground which moves a short distance before disappearing. The Fireball can be useful for edge guarding. Partly inspired by his Fireball move that he has in Blade Strangers.
Grab: Tow Rope
Quote uses the tow rope that is used to carry Curly around as a long reaching grab. Can also be used to latch onto ledges.
Aerials
Neutral Air: Polar Star
Same as jab in a manner similar to Mega Man's neutral air. Again I feel like the Polar Star should be represented twice since it's the main weapon you use for at least the first half of the game.
Forward-Air: Snake
Quote shoots the Snake weapon which promptly falls to the ground before disappearing in a manner similar to Game & Watch’s forward air. The level 3 variant can go through passable platforms, as the original weapon in Cave Story could shoot through walls.
Back-Air: King’s Blade
A backwards slash from King’s Blade.
Up air: King’s Blade
Quote swings upwards with King’s Blade. I know I’m using King’s Blade for a lot of his attacks, but its to help give him some melee moves in the midst of his heavy projectile moveset.
Down-Air: Machine Gun
Quote points downwards and shoots a barrage of shots from his machine gun that travels a short distance. It actually travels very far in Cave Story but I think the range should be lowered for balancing purposes. If the power meter is level 3, Quote will move upwards while using this attack making it a useful recovery move (though he’ll have to touch the ground to be able to float with it again)
Smash Attacks
Forward-Smash: King's Blade
Quote prepares to swing King’s Blade forward and then does so with a lot of strength. If the power meter is level 3, King’s Ghost will appear like in the actual game and deal a lot of quick rapid damage to the enemy. Although the level 3 variant is much stronger, it also has a ton of endlag.
Up-Smash: Machine Gun
Quote charges his machine gun and fires it straight above him. Sort of like Inkling’s up-smash except the damage comes from the actual bullets meaning you don’t get launched up at the very start.
Down Smash: Fireball
Quote shoots the Fireball weapon in the front and then in the back. Similar to Isabelle’s down smash.
Special Moves
Neutral B: Spur
Think of this move as a hybrid between Samus’ neutral B and the super scope item. Tap B to shoot a single small projectile that is slightly bigger/stronger than Quote’s Polar Star jab but takes longer to shoot. You can also hold down B to charge down a more powerful shot, with the strongest shot taking about 5 seconds to charge and being similar to Robin's thoron. When the charge is at max power, you can hold onto the shot for as long as you’d like and even jump/move, but you will be able to use any other attacks or dodge. You can shield to cancel the shot, however unlike Samus’ charge shot you will have to recharge it again from scratch.
This is the only weapon in Cave Story that does not require a certain weapon level to use since you manually charge it from level 1 to the max level. As a result, it is completely immune to the weapon power system that the other weapons would have.
Side B: Missile Launcher
Quote pulls out his missile launcher and shoots it either to the left or right. Essentially a faster version of Snake’s side B except the missile only goes straight. When your power meter is high, the missiles would turn into super missiles which are orange and are much stronger.
Like in Cave Story, the missile launcher would have ammo. You can regain ammo either by waiting for a while or by dealing damage with other attacks.
Up-B: Booster v.2.0
Quote flies in one of the four cardinal directions using his jetpack. It’s essentially Pikachu’s up-B except it's not as fast, Quote’s body doesn’t hurt anyone during the move, and Quote is able to use a few of his aerials during the attack.
Down-B: Bubbler
Quote shoots bubbles in front of him that will deal small damage and knockback to enemies. When your power meter is level 3, you can hold Down-B to have the bubbles surround Quote and then release the button to have them launch in a direction of your choosing.
Final Smash: Soldier’s Barrage
Quote hits the opponent(s) and then a cinematic happens where every weapon in the game is launched at the enemies. Quote ends the attack with a slash with King’s Blade, where King’s spirit can be seen charging at the opponent along with Quote.
If Curly is unable to appear as an echo fighter, then she would appear in this attack shooting at the enemies.
