A: Slash (Moves sword to one side)
AA: Double Slash (Moves it back the other way)
AAA: Slash Cross (Brings it up over his head and down vertically)
S-Tilt: Jade Crusher (punches with his claw)
U-Tilt: Cannonball Lifter/Sky Splitter (The two are very very similar)
D-Tilt: Leg Slash
F-Smash: Piercing Strike
U-Smash: Midnight Launcher (With Charge)
D-Smash: Stomping (Charged version)
Dash Attack: Rook Splitter. This one's a powerhouse, but there's a long startup lag and a long ending lag. It's a high risk, high reward move.
N-Air: Similar to a held Back Spin Slash. Nightmare spins his sword around in the same way and loops around twice, but maintains his form afterwards.
F-Air: Armlet Crusher.
U-Air: Night Annihilation. He spins his sword twice with his claw before returning to form.
D-Air: Nightmare thrusts his sword downward while kicking one of his legs up with the sword between thim. He holds his sword by his left arm, and the move has a spike strong at the tip and mid-grade at the center.
B-Air: Nightmare punches with his claw. Does a little damage but is very quick.
Neutral B: Earth Splitter. This one charges for a second, gaining power as it goes on. If let go before, it does relatively low damage and little knockback to avoid spamming, just enough to keep opponents from getting too close. If it is full-charge, it stuns the victims for a second before sending them off with a pretty good knockback. This only happens if they hit the brunt of the sword. If they get hit from above, it doesn't stun but has medium knockback. Does burn damage regardless. Has super armor when dropping the sword.
Side B: This works somewhat like Marth's Side B. He first spin attacks, then moves into a low-claw stance, then attacks upwards, putting his claw and sword upward, then smashes it into the ground, then switches hands behind his back and nails the opponent from the side.
Down B: A counter, using the same animation as a forward guard break.
Up B: If on the ground, Nightmare will throw Soul Edge into the ground, step on the bottom of the sword sticking out, and jump, grabbing his sword in the process with his claw and flipping himself. If in the air, Nightmare will steady his sword downward, toss it forward, and propel himself up and forward in the same manner. This does little damage but has a combo streak if hit right. This is a great forward recovery but is an average upward recovery, slightly less than Ike's. He isn't in a helpless state afterwards, but can't use B-moves.
Grab punch: He hits them with the sword from above, like in his Hilt Impact.
F-Throw: Hilt Impact. He slams them forward with Soul Edge's hilt.
B-Throw: Soul Devour. He grabs them by the neck and throws them backwards.
U-Throw: A modified version of Unholy Terror. He pierces them with his sword and thrusts his sword upwards, sending them off.
D-Throw: Witch Hunt. He forces the foe into the ground with his sword and pulls it out for a 3-hit combo.
Final Smash: Nightmare flails his sword back and forth like one of his win animations, until a Soul Charge is complete. He then takes the sword and smashes it into the ground, causing massive damage with a large hitbox. If the opponent has more than 45% damage it'll be a one-hit kill. But the attack is dodgeable in the air or with a side-step.
