parents, Chrom and Rin Molybden, were researchers a Biotope Company which was studying cutting-edge technology. After they confronted Professor Zed, they were run off the road and before their vehicle exploded, they managed to push Coco to safety where a Zarude found it and raised him. Zed didn't tell anyone of the incident and continued to work on his research for another 10 years.
When he encountered Koko after Satoshi brought him to the lab, he made the connection to who his parents were but decided to tag Koko
to track him as he had lived in the forest all his life and the professor thought he could lead him to the source of the power he was researching, which Koko
ended up doing.
He brought a mecha into the forest and he used it to try to fight off the Zarude and the jungle Pokémon who protected their jungle home. After being defeated, he was arrested by Officer Jenny.
