Nemu's body is a Gigai designed to withstand fatal wounds and is immune to various poisons, containing various toxins and serums Mayuri stored in her that make her highly dangerous to whoever eats her or attack her internally. While her Gigai is also composed of highly regenerative cells that her brain regulates, Nemu can still suffer pain and carries around a variety of antidotes to be used as she sees fit. In addition to having superhuman strength, she is also capable of boring through obstacles by rotating an arm at high speeds with the hand functioning as a drill-bit while using parts of her soul in her more devastating attacks. Nemu does not normally carry a "zanpakutō", but she is shown to have one in an illustration in the artbook "All Color but the Black" that takes the form of what appears to be a thin katana.
