Enemies:

	Gezora The most common enemy, Gezora will emerge from nearby temples, which can hold up to three Gezoras, and rush Mothra to try and collide with her. Gezora can't move backwards.
	Hedorah The vile Smog Monster, Hedorah is found lurking in nearby bodies of water and will toss sludge at Mothra when she approaches. Hedorah will not move, and is immune to being caught up in Mothra's webbing, but can be destroyed by it.
	Minilla The easiest foe Mothra will encounter, Minilla will simply walk horizontally over and over again, firing Radioactive Smoke Rings on occasion, making him an easy target for Mothra.
	Godzilla Mothra's most dangerous adversary, Godzilla will rush at Mothra in an attempt to collide with her. If Mothra is lined up alongside Godzilla, he will unleash his Atomic Ray to strike at her. Godzilla is immune to being caught up in Mothra's webbing, but can be destroyed by it.
	Volcano Found only past the first stage, the volcanoes are immune to all attacks, and can't be destroyed. The volcanoes will be constantly spitting out chunks of lava at Mothra.

Enemy Attacks:

	Sludge - Hedorah A pile of sludge discharged by Hedorah. This attack will fly upwards, before hitting a area below Hedorah's own position. Because of this, Mothra will be safe from this attack if she is above Hedorah and far enough away not to be hit by the sludge when it's first thrown.
	Radioactive Smoke Rings - Minilla Minilla's smoke rings will travel horizontally across the screen after being fired.
	Atomic Ray - Godzilla Godzilla's trademark attack, his atomic ray will travel horizontally across the screen after being fired.
	Lava Fling - Volcano A large chunk of lava tossed into the air from the mouth of the volcano, these piles of lava will be flung all over the surrounding area.
