If moveset submissions are constantly open, I'd like to suggest one for Nico. She's one of my favorite Marvel characters and her powers are really interesting.
Nico Minoru
Up Special: Take Flight. Nico surrounds herself with a spectral swarm of bats and rises into the air, her trajectory being fairly controllable for a few seconds. Despite granting her a high recovery distance, this move has no hitbox at all, which makes it risky to use. On the positive note, this is the only move that sends her into a freefall and this can be nullified if she cancels it into another of her specials mid-flight.
Side Special: Failsafe. Nico levitates her staff in front of her and spins it with a hand gesture. If any attack connects with the staff during this animation, the staff's protection mechanism activates, blocking the attack and retaliating with a powerful scarlet blast of energy. If the attack is a projectile, it will simply be reflected and its ownership will be transferred to Nico.
Down Special: Blood Sacrifice. Nico runs her thumb through her Staff of One, dealing herself a small amount of damage at the cost of charging her Assist/Super gauges slightly and significantly increasing her lackluster physical attack power. Nico can use this move normally five times per stock, then which its cost will increase drastically.
Neutral Special: Staff of One. Nico closes her eyes and holds her staff in front of herself and then casts a spell with a shouted incantation. The four available spells once she uses them appear around her in symbols and can be chosen with directional inputs. If the special button is tapped instead of held, she's swiftly casts a random spell. Nico has 22 spells available for this move which are the following:
- Hot to Touch! Nico shoots a fireball from her staff which sets anyone it touches on fire and creates a burning barrier if lands on the ground.
- Baptism with Thunder! Nico shoots a ball of electricity from her staff which shocks anyone it touches in place and hits multiple times.
- Sub-Zero! Nico shoots a small volley of icicles that freezes opponents in place.
- Sticky Fingers! Nico creates a large puddle of sticky goo under her feet that slows down opponents.
- You See Me Now! Nico temporarily becomes invisible and takes reduced damage from attacks.
- Fireworks! Nico shoots a magic projectile that curves upward and vacuums opponents before exploding.
- Gotta Go Quick! Nico gains a pair of wings on her ankles and temporarily increases her ground speed and jump height.
- Birthday Girl! Nico creates a large, wrapped present, which gives an item if she opens it but explodes if an enemy touches it.
- Jetpack! Nico creates a jetpack on her back and rapidly flies diagonally upward, knocking away enemies along her way.
- Stockholm! Nico creates a pink vortex in front of her. If it hits an opponent, it summons their assist character to her aid.
- Sweet Dreams Made of This! Nico creates a blue vortex in front of her. If it hits an opponent, it sends them to sleep.
- Do Not Enter! Nico creates a barrier around her that reflects projectiles.
- Watch Out, Magic School Bus! Nico creates a portal in the air, which drops a small school bus after a short wait, acting as a heavy projectile.
- It's Cold Out There! Nico shoots a beam that creates a comically large snow hat on anyone it hits, slowing them and growing their hitbox.
- Safety Hazard! Nico turns the platform she stands on into a trap. The first character that steps on it will drop down with a weak spike.
- I Hate Dolls! Nico creates a toy clown which slowly moves forward and stops an attack.
- I'll Take That! Nico creates a spectral hand that swipes ahead, stealing any items an opponent might be holding (or their health, if they don't).
- Medkit! Nico heals herself slightly.
- Time Capsule! Nico swings her staff. In the next match, she'll start with a random item.
- Throwing Darts to Map! Nico teleports into a random location on the stage. It is more likely to carry her to safety.
- Copycat! Nico shoots a random projectile from another character's moveset.
- Metal Fatigue! Nico creates a large cloud that deals looping damage to any character with any metal armor or body parts.
If Nico chooses a spell she used before, the magic fails and she'll get a random detrimental effect, ranging from being trapped in a lengthy animation where her staff shoots bubbles to damaging herself. Then, they'll be removed from her spell pool. If all spells are spent, she'll just shoot a simple, weak magical zap.
Ultimate Attack: Walpurgisnacht. Nico mumbles the incantation for her staff, then shouts "Walpurgisnacht!", holding it forward with two hands as a large, red magic circle appears behind her. Then The Staff of One showers the stage with random dark magic attacks. Burning skulls fall from the sky, platforms turn into lava, dark clouds poison and shadowy beasts attack other players. After she's done, Nico telekinetically gathers all the resulting rubble and crashes it under her, not unlike a magic meteor.
