Frisk (Undertale) Discussion: The Pacifist or The Genocidal

Moveset inspiration: Specials will be based on the ACT, ITEM and SPARE options in Undertale, while all other attacks will be based on the different weapons found in the game.
Gimmick: Hitting opponents with attacks other than the specials will increase the player's LV gradually, with a maximum LV of 19. A high LV will increase damage in A attacks but lower the damage of Specials, give your attacks slightly more endlag, make your recovery worse and make all dodges slower and shorter, as well as make your shield easier to break. Basically, you become a glass cannon.
Jab: A slightly delayed swing with the Stick. Unlike every other A attack, this move takes two hits to reach LV2 rather than just one like the other A moves do
Ftilt: A regular punch with the Tough glove. All tilts have medium LV increase
Dtilt: A low sweep with the Balette Shoes.
Utilt: An uppercut with the Tough Glove, which can be used as a combo starter.
Dash attack: A pirouette while wearing the Balette Shoes, hitting three times. Slightly above medium LV increase

Nair: A quick spin in the air while holding the Stick. Medium LV increase
Fair: A heavy swing forward with the Torn Notebook, working as a slow kill move. Above medium LV increase.
Bair: A surprisingly quick slap backwards with the Torn Notebook, which after the initial hit has small multiple hits from pages flying out. Slightly above medium LV increase
Uair: An upwards hit with the handle of the Empty Gun, very similar to Bowser Jr's Up air. Medium LV increase
Dair: Frisk angles the Empty Gun downwards in a slow startup, then tries firing the gun only for smoke to come out instead due to the gun being empty. Still, the smoke is a powerful meteor smash with above medium LV increase.

Side Smash: When below LV 5, Frisk slashes forward with the Toy Knife. At level 10 they use the Worn Dagger for a bigger hitbox and faster startup, and at level 15 they switch one final time to the Real Knife for a big decrease in endlag, making it pretty spammable. Very high LV increase.
Up Smash: An upwards smack that kills vertically, with pretty big endlag. High LV increase
Down Smash: Frisk does a handstand, then split kicks with the Balette shoes while upside down. Very horizontal knockback, and has high LV increase

Neutral Special: Frisk starts talking with any opponent standing in front of them, which traps and damages them rapidly.
Side Special: Frisk throws Dog Residue at the opponent in an arc, which deals a random amount of damage like Peach's turnips.
Up Special: After turning into the red SOUL, Frisk floats upwards quickly or runs in a chosen direction if used on the ground, like if the Run command had been used. The attack gets much slower with a higher LV, but the actual height doesn't decrease much. On the ground it has a multihitting hitbox, making it another useful way to rack up damage in a "pacifist playthrough"
Down Special: A dust cloud appears in front of Frisk and splits into four smaller clouds, moving in all four diagonal directions like the animation that plays when an enemy is killed or spared. In this case, it's Frisk "sparing" anyone who's in front of him, which is an early killmove like Jigglypuff's rest. This move has more range forward than Rest in exchange for being a bit weaker than it.
Final Smash LV1: Stars rain down from the sky and split into smaller stars, like (SPOILERS)'s attack Galacta Blazing. The hardest to dodge out of all the final smashes
Final Smash LV2-18: Everything on screen freezes as the ATTACK scale appears, as the player has to play a rhythm game of sorts with the incoming white bars. For each one that hits, Frisk gets an increase in power and speed. A total of 10 bars appear, in a random rhythm. The boost in power lasts for about as long as the other transformation Final Smashes, like Wario-Man or Giga Bowser.
Final Smash LV19: Frisk hits whoever is standing in front of them with full force, which makes the LV counter hit LV20. Then, Frisk's sprite changes to look like Chara and they start slashing away at the foe, guaranteeing a One Hit KO.

No ideas for Grab. Something with Checking the opponent, maybe?
