Mothra is a flying Kaiju mob in Minecraft. She only spawns in Extreme Mountains biomes and is tameable with Cobwebs obtained with Silk Touch. Her presence while fighting Mobzilla gives all players a perpetual Regeneration effect.
Swarm - Spawns tons of moths that literally swarm any targets and deal massive amounts of damage collectively.
Silk Attack - Encases the target in tons of webs, slowing it down and rendering it immobile.
Explosive Breath - A much weaker version of Mobzilla's atomic breath.
Supersonic speed - Mothra flies at over 40 blocks a second, making her the fastest mob in Minecraft.
