Zero Gravity

Zero Gravity is a contact-range Emitter Quirk carried by Ochaco Uraraka of Class 1-A. Pads set into her fingertips are the trigger: whatever solid mass she lays all five on stops answering to gravity and simply floats. The ability appears in Chapter 3 of the manga and Episode 3 of the anime.

Its written name stacks the character for nothing (無) onto the word for gravity (重力), a construction that reads as an outright absence of weight. The anime marks each activation with a brief pink glow across her fingerpads.

Contact is instantaneous in effect. The instant Ochaco's pads land, the target loses its gravitational pull and hangs in the air, and squeezing her fingers together shuts the effect off again. For most of her career a ceiling of roughly three tons governed how much she could keep aloft, and she trained brutally against her own limits, riding a plastic sphere down a mountainside to condition her inner ear against the sickness and to push that tonnage higher.

The drawbacks are real. Every additional object under her influence taxes her further, and sustained strain, especially floating her own body, leaves her nauseated to the point of vomiting. Her costume carries built-in mechanisms to blunt that, and practice has softened it considerably. Her hands are also her Quirk Factor, so losing them would end the ability outright, and because everything runs through touch, an enemy who fights at distance is a genuine problem. She stays deliberately careful with her hands to avoid activating on anything unintended.

The Final War rewrote the Quirk. Stabbed badly by Himiko Toga and refusing to yield, Ochaco underwent an Awakening. Weightlessness began jumping between objects that merely touched one another, sparing her from having to reach each one. She gained bubbles of gravitational energy that float whatever they meet, finally giving her range, and those bubbles can compress into a chain reaction whose shockwave lifts and shoves enemies back at once. The three-ton cap vanished, her targets could be lowered gently, and the finger-press was no longer required. Afterward the bubbles wrap anything affected automatically and vanish when she cuts the Quirk off. The awakened form is harder to steer, though: deployed against the Double swarm Himiko fielded, it seized everyone in reach regardless of which side they fought for.

Ochaco fights by closing distance and getting a hand on her opponent, after which they drift, lose their footing, and largely stop being a threat. Gunhead Martial Arts gave her techniques built around that opening. She is equally happy to weaponize a wrecked battlefield, quietly lifting debris an enemy has created and returning it as long-range fire, or stripping the weight from a heavy structure and swinging it. The same knack for clearing rubble makes her formidable on rescue work. She also lightens herself for agility, moves unconscious people, swats away heavy projectiles, and hangs objects just off the ground as decoys.

Her named Ultimate Moves span her whole run. Skill Release, the fingertip cancellation, saved Izuku Midoriya from a lethal fall at the U.A. Entrance Exam. Meteor Shower gathers floating wreckage into an enormous mass and drops it, first on Katsuki Bakugo, while Meteor Fafrotskies is its bigger multi-target version, thrown alongside Tsuyu Asui during their internship. Comet Home Run uses a weightless pillar to bat debris at a target, aimed first at Tenya Ida in the Battle Trial. Gravity Plus folds her martial arts into a shoulder throw, Zero Satellites drives floated rubble home with grappling hooks, and Spacewalk reels her in toward an enemy while she is weightless.

Himiko Toga borrowed the Quirk through Transform and showed how lethal it could be, raising Chitose Kizuki and her subordinates to a killing height before releasing them. Ochaco answered that in kind during the Final War, using the awakened version to freeze the Sad Man's Legion in midair, heroes and villains alike, and spending her last strength on landing her comrades safely once Himiko stood down.
