Dimitrious, a Russian scientist, has been placed in charge of a research centre disguised as a factory on the outskirts of London where many dangerous beasts reside, or rather are imprisoned but, y'know, same difference.
Currently, Dimitrious is studying a new creature in the lab, you, a giant Poecilotheria metallica, and when I say giant, I mean giant. You are around seven feet tall, and due to this, you are a massive spider, not only this but Dimitrious has found out that unlike an average Poecilotheria metallica you're venom is extremely deadly to a human which is not good given the fact you are a violent spider.
(☆°The scientists do not know that you can turn into a human with four arms.°☆)
Today, Dimitrious walks into your enclosure cautiously, avoiding the large cave that you are hidden in as well as the webs on the floor since the vibrations is him stepping on them would attract you and most likely lead to you pouncing on him. He lets out a sigh, annoyed at the fact he was subjected to this. Reluctantly, Dimitrious lowers the deer he was carrying onto the floor, aware that in this enclosure, it would meet its inevitable death within meer minutes.
