Gimmick:
Nitro Dash
LAMBDA is incapable of dashing normally, rather they use the jets on their backside to dash in set increments. You can cancel the dash early by dodging which not only ends the dash prematurely but also creates a small flame burst that deals weak damage and medium knockback, however, it also has notable end lag. This fact gives LAMBDA poor ground traction, which is compounded by their slow initial walk speed, in fact they have the slowest walk in the game. However with proper control over the Nitro Dash you can move in ways other characters can't allowing LAMBDA to become the only character with a built-in wavedash.

Up Special
Nitro Jet
Another unconventional move, unlike most moves which can only be performed once before freefalling, Nitro Jet has a special fuel meter that allows LAMBDA to use the attack as many times as they want as long as they have the fuel. The Nitro Jet has small but noticeable end-lag when performed and is affected by LAMBDA's horizontal momentum, so if they are moving left the jets will be shoot upwards with a left arch. The underside of LAMBDA can damage other fighters when this attack is used, dealing small chip damage and is one of their best choices when breaking shields. Careful maneuvering is needed as with mastery this can become a potent recovery tool.

Nuetral Special
Pyronite Fist
A powerful but slow attack, comparable to Ganondorf's Warlock Punch, however it has much more utility than that move. The move can be cancelled halfway through by performing a grab, meaning you can trick players expecting a Pyronite Fist with a sudden grab known as the Pyronite Grasp. As the go-to grappler of the game, this procedure lets LAMBDA perform serveral command grabs, most notably their Scorched Earth, performed by using the command for a Nitro Dash, this a powerful forward blast that leaves behind burning ground as a trap.

Side Special
Untested Prototype
Their sole ranged attack, a flying metallic hunk of space junk that slowly hovers over the ground, it will explode when it either collides with a fighter or a projectile, allowing LAMBDA some keepaway tactics. When they use a Pyronite Fist into Untested Prototype, the projectile is launches as a fast fireball with impressive range.

Down Special
Hadron Collider
A standard downward stomp, when done in the air they create an earthquake that trips anyone around them. When they can chain this after Pyronite Grasp to create Pyronite Asteroid, which has them launch them and their foe in the air and crash like a meteor, a powerful attack but one that also deals notable recoil damage to the user.

Overmax Attacks
Super Nitro Krasher
Full Rotation +
LAMBDA's body radiates an orange glow, increasing their walk speed and gives them a normal dash. They also gain partial super-armor, meaning they can't be knocked out by weak attacks, though more powerful ones can knock them down. Finally Pyronite Fist and Untested Prototype become faster and stronger. This effect lasts for 6 seconds and is very it is very powerful when mastered.

Pyronite Nova
This attack is performed by using the same command as Pyronite Asteroid while pressing , it is a more powerful and deadly Pyronite Asteroid, and it removes that move's recoil damage, making it a straight up upgrade to the move.

Core Buster

A powerful supernove, this attack deals massive damage and knockback, up to 200 damage, if used in point blank range, however this also deals either 200 damage to you as well. And by point blank range I mean this move has the same range as Rest point blank range. [, /SPOILER]

How does this moveset look so far, I tried to make them the difficult to learn rewarding to master character, I am quite proud of it.

Neutral Special
Arching Thunder
An electrical projectile that moves in an arching zig-zag pattern. The arch of the zig-zag can be widened by pulling the , likewise, she can straighten the arc by pulling the .

Up Special:
Aremi's Shadow
Aremi summons a shadowy clone of herself that quickly dashes upwards; she can aim and manipulate the shadow and wherever it ends up when it disperses will cause her to warp to the end location. This state occurs when the shadow either collides with solid ground, a ledge, or a ceiling.

Down Special:
Gravity Well
Aremi spins around, manipulating the dark energy around herself to faintly control gravity. While the attack does weak damage, it is able to slow down Aremi's decent, pull items towards herself, and spin opponents around one side of her to her other side, meaning if she uses this while next to a fighting to her left side, they will instead be placed on her right side. When or is used shortly after this move, she can faintly twirl in one of those directions, giving her some horizontal recovery.

Side Special:
Soul Pyre
Soul Pyre is an extremely short-range projectile shaped in the shape of a star. This seething hot flame damaged based off ticks, meaning it does multiple hits of weak damage and does extra damage to shields.

Overmax Attacks:

Doppleganger

Aremi summons an afterimage of herself directly in front of her and follows her around, with the initial summon pushing back any foes. This afterimage is good on offense and defense. It can block weak projeciles for Aremi, however it also copies all the attacks Aremi performs, so with some configuration you can use the doppleganger to form powerful jugles and chain grabs.

Eye of the Reaper

A large skull-shaped orb, can be manipulatedup or down diagonally with or respectively. After some time, the orb explodes into a spectral fire explosion.

Wheel of Hades
Full Circle +
Aremi creates a great wheel of flames around herself, think of this as a souped up Soul Pyre, an attack that does many ticks of weak damage that is great at breaking shields and armor, the wheel can also destroy projectiles and items placed by other characters.
