Ham, known in the Japanese version as Hare, is a supporting protagonist from the Monster Rancher anime series. He is characterized as a cunning and highly intelligent monster who joins the group of main characters as the last member. His primary background involves being recruited by Genki and Tiger in the city of Aurora, where they encountered him during a monster battle held to win prize money.

In terms of personality, Ham is defined by his sharp, shifty nature and a strong love for money. While he is the smartest member of the team, he is also the most easily tempted by selfish desires and financial gain. This greed often puts him at odds with the more straightforward and honorable Tiger, who holds a long-standing grudge against Ham stemming from a cheating incident during their first match against one another.

Ham’s primary motivation revolves around self-interest and monetary reward. However, as the story progresses, he becomes a more reliable member of the group. His role within the team is largely practical; once he gains the trust of the other Searchers, he applies his sharp mental faculties to become the group’s accountant and financial manager. His notable abilities include remarkable skill with an abacus, which he uses to handle logistics and planning for the team.

His key relationship is the tense rivalry with Tiger, characterized by mutual distrust and frequent conflict. Though he initially operates from a selfish perspective, Ham does develop a degree of loyalty to the group, demonstrating a developmental arc from a purely greedy opportunist to a cunning but occasionally dependable ally.
