Ok hear me out:
Nezu is an scp described as an antropomorthized chimera (with the prevalent part being of a rat) with astounding intelligence
That was born by inserting a rat and a computer mouse into scp-914.
It is an apollyon class that can cause end-of-the-world scenarios if in contact with Basically anything.
It has the power to directly interact with anything not created by nature.
It was initially peaceful but after some experiments done by the foundation it escaped, gaining a twisted personality.
It was captured several times but it escaped everytime, so the foundation marked it as impossible to contain. After several escapes nezu decided that it had enough, so he infiltrated in the beta of a manga named "my hero academia" were he took an important place as the principal of the school, so he could costantly mock the foundation for their failure at apprehending it
