Liigii is the twin brother of Niogee. As a child, he and Weegee were best friends. But when they were adults, Weegee insulted Liigee's family. This caused a rivalry between the two. He was the one who discovered Demon Compound A, which can make any living thing into a killing machine. He used it so much that the strength that was gained from it stayed permanently. He also founded Demon Frontiers Incorporative. This helps Demons that were having a hard time in the Epic Universe. He was later killed by Deegee.
