The user is able to manipulate oxygen atoms that are smaller than normal, and can pierce any material. Down at the atomic levels, all matter forms a mesh. When Micro-oxygen is introduced, it slips into the mesh of atoms. When it is forced at high pressures, it has enough to force to cause the de-cohering of the surrounding atoms, thus disassembling the target, and also violently reacting with any surrounding component substances, which would create combustion.
