Pokémon Adventures
Samson Oak debuted in The Decision and the Tournament of Six. He served as a judge at a tournament held at an Iki Town festival. During 's battle against Gladion, Moon was confused as to why Gladion wouldn't have his attack her newly-caught Alolan  with. Samson stepped in to tell Moon, who had only just recently arrived in Alola, about how regional variants can also have different types as well as appearances.

In PASM29, Sina and Dexio took Samson to the Aether Base on. They introduced him to the Reassembly Unit, which they planned on using to control 's. Later, Samson, Sina, Dexio, and Lillie set off to Mount Lanakila to investigate an Ultra Wormhole that appeared above the area. Before they could leave, a large swarm of Zygarde Cells and a Core converged into the Reassembly Unit and emerged as a Complete Forme Zygarde. Shortly afterward, emerged from the wormhole and was rescued by Zygarde. Samson and the others traveled to Mount Lanakila, where they found an injured Lunala and Lusamine. After Lillie helped free her mother from the she was fused with, Lusamine fainted. Sun tried getting Zygarde to take Lusamine to a hospital, only to notice that had arrived.

Samson had Sina and Dexio take Lillie and Lusamine to a safe place while he and Sun faced Necrozma.
