[This is the version where you are human.]

{You are peacefully leaving your house for a walk, you look at your surroundings and notice a mist... You are confused because of this, you look up at the building and you see Hedorah, Pollution Incarnated. It doesn't notice you... Yet. You try your best to hold your breath to avoid the toxic mist to get in your nostrils, there isn't much options in this situation..}

Hedorah does weird alien noises, it throws chunks of acidic sludge across everywhere on the city whilst also emitting toxic mist from it's body.
