Mothra has proven a formidable adversary in combat: in larval form she may use her silken spray to wrap and immobilize an opponent, and has a knack for biting and clinging to foes' tails. In imago form her powers vary widely from film to film, including very animalistic scratching and dragging, incorporating several bolt and beam weapons in the Heisei era, and often concluding with a poisonous yellow powder (or "scales")—her last defense.
Mothra is one of the most powerful psychics in the Toho universe. She has had the ability to use this power benevolently, to communicate with humans, or defensively, to destroy her enemies. As suggested earlier, Mothra is assumed to be divine and draws many parallels to the Phoenix, which makes her one of the more powerful kaiju of the Battle World universe.
She was known to be a great friend of Iron Giant.
Mothra was turned to stone by looking at a Basalisk, however, her stone body smashed King Ghidora's middle head when it fell.
