Manuke (Japanese: マヌーク Manuke) is a minor supporting character who appeared in White—Victini and Zekrom and Black—Victini and Reshiram. He lives in the arid desert, where he works for his village's leader Ravine.
In the movies
In White—Victini and Zekrom, Manuke witnessed, along with the rest of the village, Damon summoning Reshiram in order to save them from a tornado and a rampaging herd of Bouffalant. In Black—Victini and Reshiram, he was seen in Damon's flashback of him asking Ravine to support his idea. After Ravine tossed Damon's book on the ground, refusing his idea, Manuke picked it up and handed it to him.
Manuke was later seen with Ravine and Luisa, along with the people of the tundra village, in both movies, where they show their support for Damon's idea.
In the manga
In the movie adaptations
Manuke appears in the manga adaptation of White—Victini and Zekrom, where he serves much the same role as he does in the movie.
