Math Teacher

A subterranean beast that resembles an old woman. They can be found in sewers, abandoned subway systems, and other dark, wet places. They hibernate every 20 years, then come out of their lair and apply for a job at the local middle or high school. These creatures love watching children suffer, and will regularly steal or "confiscate" the belongings of their students. Math teachers also have the unique ability to warp time and space, making their class period last longer than the others. Every couple of years a child will go missing at school and then a few months later they'll find the body in the sewer. There is still some speculation, but theorists suggest this was the teachers fault.
