Villain of Diseases:
He grew up in a small city. He lived with his Dad since his parents were divorced.He grew up with no (everyone laughed at him at school because of his looks and his family) friends, so he had books as his companions.He would spend most of his time reading and reading. Sometimes, barely even eating. Once he turned 18 years old he got a job at medicine packaging company. There he would earn money and save his money. Once he had enough money, he built his own laboratory. He tested many of his created "potions", which mostly turned out to cause illnesses and diseases.
Then one day, he created a potion where when you drink it, the first person it sees after you drank it, you will serve them. So, he tricked people into drinking them. Once he had raised an army of innocent civilians, he sent attacks all over the world.
And with his other potions, he made animals drink them, then, the animals carried on the diseases to people, and people to other people, anyone who had the disease known as the "red illness" died in 2-3 days.
He still lives today, in his underground laboratory.
