World is full of despicable life. Microbes everywhere. Unseen dangers lurk behind every corner. The only solution is cleansing filth of life in its entirety.
Behavior
This creature sterilizes every equipment he touches. In its basest form, it lays a towel where it goes. This seemingly innocent behavior betrays future Cleanser. In time, it will start bringing in sanitizer. It will spray equipment which he uses as it is filthy. Full of microbes and was used by the unclean masses.
This creature, once human now lives in nostalgia of better times when everyone had to social distance and to wear masks. He would gladly do so again and some of them continue this practice. In its hearts, it believes that you are inherently filthy creature, a vessel of plague, a threat to its continued existence. If given a chance, it will cleanse world of microscopic life. As it stands, its soul earns for a new pandemic to ravage the Earth for its life is one of constant fear of the unseen. Its existence is meaningless without it.
