Isaac Lovell is a childhood friend of Zeal's from Cianwood City. Nowadays, he works as a Pokémon breeder in Almia. When Glavo disappeared during the events of Ranger-2, Isaac took care of Zeal's mons for a few months while the latter went off on his own. Isaac is very laid-back in most cases, but gets very exhausted trying to keep up with everything going on in Zeal's life. Despite this, he's one of the few people who knows almost every detail Zeal is aware of.
