Being as fond of caregiving as he was, the caregiver discovered medicine that was helpful for curing pokemon, as well as others that weren't so effective.
One day, he found a weak Marowak a wounded one that, as time went on, he grew more and more attached to. He would spend countless hours with his pokemon, days even, just feeding them, playing with them, and caring for their wounds. Legends tell of a mysterious man a caregiver, one of the happiest you'd ever find.
