Zero Gravity allows Ochaco to remove the effects of gravity from solid things upon touching them with the pads on her fingertips.
The targets lose their gravitational pull the moment Ochaco makes contact with them, effectively making them weightless. Through Zero Gravity, Ochaco can make anything solid float in mid-air as long as they are within the weight limit of her Quirk, which is around three tons. She is able to activate or cancel her Quirk's effects by closing her fingers together.
As part of her training, Ochaco put herself into plastic sphere that would tumble down a mountain, all in effort to get her inner ear canals used to zero gravity and reduce nausea, all while increasing how much weight she can lift.
The more objects Ochaco has under the influence of her Quirk, the more she will struggle to keep them afloat. Continued strain and floating herself results in her feeling sick and nauseous, even to the point of vomiting. This can also happen when she uses the Quirk on herself to float for too long. With training she has managed to mitigate this drawbacks considerably.
Due to her being limited to floating objects from only her hands, which are also her Quirk Factor, Ochaco will be unable to utilize her Quirk if she loses the said limbs.
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 continuously float up and lose their footing, severely limiting, if not eliminating, their fighting capability. After learning martial arts with Gunhead, she 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 gather wreckage without an opponent noticing, expertly exploiting the collateral damage of a destructive Quirk. Ochaco can release floating rubble on enemies as a long-range projectile attack or remove the weight of certain heavy structures, holding onto them to use as an improvised melee weapon. This ability to easily clean up disaster zones also makes her useful for rescue missions.
Ochaco can further use Zero Gravity to remove her own weight, increasing her agility, make unconscious allies and enemies weightless to transport them easier, deflect heavy, incoming projectiles and create decoys by making objects levitate slightly above the ground.
Because prolonged usage of Zero Gravity causes nausea, Ochaco had several mechanisms installed in her costume in order to mitigate its effects. She 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.
Additionally, while having temporary access to this Quirk due to the use of her own given Quirk Transform, Himiko Toga demonstrates the potential lethality of Zero Gravity; after causing Chitose Kizuki and her henchmen to float up to a dangerous height, she releases the ability and allows them to plummet to the ground, killing them all instantly.
