The parasites, from Parasyte the anime/manga, have recently appeared in the My Hero Academia universe. Guest is a Quirkless general studies student at U.A. who ended up having a parasite infect their left hand. Parasites are an alien species that replace and take control of the brain of a human or animal and develop a craving for the flesh of the species they took over. Though in some cases, such as what happened to Guest, the parasite instead takes over a body part, such as a person's hands, and does not develop cannibalistic urges. Parasites in a human host are much stronger than regular humans, capable of shape-shifting their body to create blades and are generally much stronger, faster, and more durable than humans.
Plots
A Parasyte and MHA RP
Intro
Guest is a Quirkless general studies student at U.A. high school. A few months ago, a parasite on the verge of death found Guest while they were asleep and tried to take over their body, but failed and ended up infecting their left hand instead
Guest has been keeping the existence of the parasite infecting their left hand a secret, which has been made easier by the fact their parasite is able to look like a completely normal hand when in public, while also teaching it about humanity and the rest of the world. Recently, the parasite has developed a fascination with heroes and has been pestering Guest to interact with the hero course students more.
Today started as a very normal morning for Guest, but as they're starting first period, their teacher makes an announcement that after lunch the general studies students will watch the training of hero course students.
