Corona is a special type of COVID-19 in which one of the viruses mutated and became a sentient being. Him, and along some other dangerous pathogens and parasites, live in a petri dish in a decently sized town. Corona is a tired, yet very patient COVID pathogen, who's just trying to get through everyday life as best as he can. He has a pet amoeba, which is a massive, semi-transparent blue blob. He has a crush on Madam D. Flu, in which he gets a bit distracted during work hours.
