Zero Gravity gives Ochaco the ability to make objects float through touch.
Ochaco has small pads on each tip of her fingers. Anything that is touched by these pads loses its gravitational pull, effectively making the object weightless. In order to cancel the effects of Zero Gravity, Ochaco just needs to close her finger pads together. Whenever Ochaco activates her Quirk, her pads briefly glow in a pink light.
Through Zero Gravity, Ochaco can make anything solid float in mid-air as long as they are within the weight limit of her Quirk. Those affected by it are unlikely to fight back since they will keep rising up and away from the solid ground until Ochaco decides to bring them down.
Ochaco has a limit to the amount of weight that may be nullified, which is around three tons. The more objects she has under the effects of her Quirk, the more she will struggle to keep them afloat, and continued strain results in her feeling sick and woozy to the point of vomiting. She can also make herself float by removing her own gravitational pull, but doing so leads her to become nauseous much quicker.
Ochaco's main battle tactic consists of using her Quirk directly on opponents by getting close enough to make contact with them through her fingers. This consequently causes her targets to float up and lose their footing, severely limiting their fighting capability, if not taking it away outright.
She can further use Zero Gravity to remove her own weight, allowing her to jump higher and farther, or create decoys by making objects of her own levitate slightly above the ground, which may serve as a distraction. After learning martial arts with Gunhead, Ochaco has developed a few moves that she is able to use in conjunction with her Quirk.
Ochaco often takes advantage of ravaged areas by using her Quirk to collect rubble, which she then releases on enemies as a long-range projectile attack. Certain heavy structures can be used as melee weapons as well, with Ochaco holding onto them after removing their weight. She is sneaky enough to be able to gather wreckage without an opponent noticing, smartly exploiting the collateral damage of a destructive Quirk. Ochaco's ability to clean up disaster zones also makes her useful for rescue missions, which she has a notable interest for.
Because prolonged usage of Zero Gravity causes nausea, Ochaco had several mechanisms installed in her costume in order to mitigate its effects. Ochaco is known to be careful with her hands so that she doesn't accidentally activate her Quirk on something or someone she doesn't want to.
Named Super Moves
- Skill Release (解除 Kaijo?): Ochaco presses her fingertips together and makes whatever she has touched stop floating. This move is first used when she saves Izuku Midoriya from falling to death during the U.A. Entrance Exam.
- Meteor Shower: Ochaco collects a large quantity of debris with her Quirk, which she then causes to fall on an opponent with Skill Release. She first used this move during her match against Katsuki Bakugo.
- Home Run Comet (彗星ホームラン Suisei Hōmuran?): After applying her Quirk's power of making objects weightless to some rubble and a pillar, Ochaco then uses the pillar to hit the rubble at her enemy. This move is first used to distract Tenya Iida during the Battle Trial.
