Black Hat, sick with the Evil Flu.

The Evil Flu is an illness that was contracted by Black Hat in "The Evil Flu", and later, by 5.0.5. and Dr. Flug.


It is unknown what the difference between the "Evil Flu" and the common "regular" flu is. It is possible that Black Hat was simply making it up, however, Dr. Flug seems to believe him, or at the very least humor him.

The flu can be passed on to other people the same way as many other illnesses: sneezing, close contact, et cetera. Black Hat believes the Evil Flu to be inherently evil, and to have "evil thoughts".
