Anton and his fellow giants once made a living by farming up in the beanstalk and harvesting magic beans, until Jack and James led an army of humans who wiped out all of them except Anton. Becoming bitter and disdainful of humans, Anton lives alone in the beanstalk.
Emma Swan and Killian Jones climb up the beanstalk to steal a magic compass. Anton finds the pair and attacks, although when he is outsmarted by Emma, she shows him mercy and refuses to kill him when she leaves. Later, Cora Mills shrinks Anton and brings him to Storybrooke. Anton mistakens David for his twin brother James who betrayed him, and tries to kill David. Cora's daughter Regina briefly returns him to his giant size, although it eventually wears off. Anton decides to start farming magic beans with the dwarves.
- Anton is based on the giant from Jack and the Beanstalk.
