Ickis is the main protagonist of the series. His method of scaring humans is the ability to grow bigger. However, due to Ickis' large ears, he is often confused with a bunny rabbit. Ickis also has feet in the shape of an elf's shoe. Ickis also tends to be on the nervous side and often has a lack of self-confidence, partly from trying to live up to the legacy of his father, Slickis, who was the academy's most renowned student. Ickis is room-mates with Oblina and Krumm, and he is also best friends with them. He goes to the Monster Academy along with many other monsters.
