Liscian (pronounced Lye-si-in) are enemies in Super Mario Bros. platformers. They look like red gnats in a big pile (like bees in "The legend of Zelda Skyward Sword" and work for Bowser. There name is based on the word "lice". They cannot hurt Mario, but once they attach to him, Mario is forced to run through the levels and increase the chances of hitting an enemy or falling into a bottomless pit because Mario is running recklessly. However, Mario can shake them off and kill them if he shakes many times. Shaking also prevents Liscian from attaching to Mario as well as running from them. They can go through blocks and enemies, but not walls.
