Chapman is a character of the day who appeared in A Watershed Moment!. He is the grandfather of Henny.

[Spoiler] Chapman, along with his Chesnaught and Robon, first appeared in a photograph Ash and his friends saw when they came to Chapman Research Lab. After the group was confronted by Henny and after a brief introduction, they were shown a video made by Chapman, who explained what happened to the land. The currently arid land surrounding the Research Lab was actually a beautiful forest inhabited by a variety of Pokémon. However, the forest began to dry up, but before Chapman could figure out the reason why, he was overcome with a certain illness. Determined to help the forest grow back, Chapman constructed a robot, Robon, to help the forest regrow. Thus, by means of the video, Chapman requested anyone who saw it to help Robon and his Chesnaught in their efforts.

Later, he appeared in a flashback where he advised Robon and Chesnaught to always look after each other. [/Spoiler]
