Trivia

 * Originally, Haichyak's name was supposed to be "Hijyak", a pun on the words "hijack" and "hyaku", the latter of which is the Japanese word for "hundred". However, Alex Guy decided to change it to "Haichyak", as he believed the spelling looked "cooler" than the original name, and he wanted to poke fun at the Dragon Ball OVA villain Hatchiyak.
