A former Neotopian citizen, who bears a grudge against Hairam for separating him and his family from his beloved sister. Herrick has a rather cool behavior on his first appearance, but soon becomes more and more aggressive. He is a former contender of the Neotopian Joust tournament. He attempts to recruit Zed to fight against Hairam, the supreme judge of Neotopia that oversees the "Ultimate Rules". After this is unsuccessful, he ignores Professor Bender's advice and takes the composite spirit Ex-Machina, thinking that he can finally kill Hairam with it. He is killed while trying to stop Ex-Machina, which he can no longer control, after defeating Kira and discovering that she is his sister Chelsea.
