Oxygen Manipulation Power: Acid has an unnamed Level 4 esper power based in manipulating oxygen. Acid doesn't gather this oxygen from her surroundings, she produces oxygen in her lungs and breaths it out into the air to control it. She can use this power to produce a gust of wind, blast the enemy with compressed air, alter the concentration of oxygen in the air such as that any kind of spark will create flames, create mirages by bending light, etc. However, since her esper power manipulates oxygen, not air or wind which is a mixture of various gasses, this indirect manipulation of air is not an effective use of her powers. She instead excels at chemical reactions.

  • Acid: Acid has the ability to combine oxygen with hydrogen ions and air moisture to create a powerful oxyacid, using wind to scatter a rain of acid drops towards the enemy. If suddenly mixed with a lot of water, the acid produces white chemical smoke that damages the lungs if breathed. Although reduced in concentration, the water contaminated with the oxyacid can still hurt those that touch it. Acid can use her control over oxygen to avoid this acid. She is skilled enough at controlling her oxyacid to specifically target the joints connecting various materials and weak parts that support a structure, causing it to collapse under its own weight.
  • Air Blocks: Acid can also combine a collection of various oxydes with the nitrogen and carbon in the air to create muddy-colored solid boxy blocks out of thin air, for example, to build a staircase to the next floor after making a hole in the ceiling.
  • Strengthening: Acid can breath in enough oxygen to cause hyperventilation under normal circumstances and then control the flow of oxygen in her body down to the cellular level to place her body under her full control. This allows her to strengthen her body to superhuman levels, both in terms of strength/speed and in durability.
