Jonathan is a character of the day who appeared in Time Warp Heals All Wounds (AG157).
Years ago, when they were young, Jonathan worked as a Pokémon pediatrician in Fuchsia City, with his wife Edna serving as his assistant. He had been considering becoming a full-fledged Pokémon doctor, rather than merely tending to their Eggs. However, this path would require him to leave town for a period to live and study in the city. Jonathan attempted to persuade Edna to accompany him, but she was hesitant. When Edna ultimately refused outright to leave her hometown, because it meant too much to her, Jonathan left her with a note, stating that he loved her dearly but needed to pursue this opportunity.
He boarded the train, unaware that Edna was chasing after him to tell him she was pregnant, and he did not return from that day on. A year after Jonathan left, Edna received a letter claiming he had died in an accident. However, in a state of denial, she did not believe this and went to wait for him at the station for years.
In the present, May's Squirtle found Edna's locket, which she had lost when she wanted to tell Jonathan of her pregnancy, and May opened it, sending her and her Squirtle back in time with Meowth. By fulfilling Edna's fondest, idealistic wish and May using Squirtle's Ice Beam to turn the rain into snow, effectively delaying the outbound train, Edna now caught up with Jonathan to tell him of their soon-to-be daughter. With the truth revealed, Jonathan remained in town with Edna.
May, Squirtle, and Meowth returned to the present, which had now been altered because of May's actions. They discovered Jonathan was still alive and well, and still worked as a pediatrician. He oversaw the hatching of May's Eevee, with Edna and his granddaughter Katrina aiding him.
