Acid

Acid was a power within the Matoran Universe, using damaging chemicals to dissolve targets. The only known users of Acid are Lehvak, the Bahrag, Airwatcher's staff, and Keelerak thanks to their Rhotuka spinners. Acid was not a Toa Element; thus there were no Toa, Turaga or Matoran of Acid.

Users

 * Lehvak
