He will make his first physical appearance in XY098.
| Venusaur is Nihei's ninja partner. Together they are the second strongest of the ninja village Ippei, Nihei and Sanpei hail from.

- The names of Ippei, Nihei and Sanpei are a play on the Japanese words for one, two, and three: "ichi" (一), "ni" (二) and "san" (三).
