Professor Cedric Juniper is the father of Professor Juniper. He studies Legendary Pokémon in the Unova region as well as the Hero's legend. He keeps a study notebook with him at all times for reference while exploring ruins and ancient artifacts. His fountain pen was recovered by his daughter after it got stuck in a Klinklang gear when Ash's Krokorok initially picked it up but didn't find it interesting and it threw it unknowingly at Klinklang. Professor Juniper noted that her father has the tenancy to loose his train of thought midway through his sentences which often makes people assume what he is going to say but their assumptions are not always what he intends to say.

Professor Cedric Juniper was studying some ruins associated with the Hero's legend which were recently discovered and while heading to the ruins he got lost inside the cave. After reuniting with his daughter who was studying the Electric Stone Cave nearby, he agreed to take Ash Ketchum and his friends with him on his adventure to the ruins as he wanted to see the ruins with his own eyes as quickly as possible because he thought that it might be the place where the Hero and Zekrom communicated.
