Saizo is a character appearing in the XY series.
Season 18: XY Kalos Quest
Saizo was Sanpei's tutor in ninja craft. Sanpei felt he was ready for the final test, so Saizo gave him a scroll to deliver to a mansion. However, the true test was to test Sanpei's skills, so Saizo disguised himself and attacked him, poisoning his Greninja with his Barbaracle. The heroes encountered Sanpei and healed him and Greninja, promising to defeat the opponent ninja.
Saizo faced them again outside a cave, but Team Rocket interfered, so he used Barbaracle to blast them off. Barbaracle was to defeat Greninja, but Ash's Froakie evolved into Frogadier and protected it. Saizo was satisfied and awaited them at the mansion, where he revealed it was all a test for Sanpei, who passed.
Season 19: XYZ
Saizo came to the Ninja Village when it was under attack of Kagetomo's Ninja Army. Saizo called his Barbaracle to block Heidayu's Bisharp's attack when Heidayu was battling against Sanpei and Ash. Ash and Sanpei were glad to see Saizo again while Heidayu recalled his Bisharp, after it was attacked by Barbaracle, and went back to Kagetomo. Saizo then joined with the rest to talk about what happened in the Ninja Village and about the kidnapping of Hanzo. Saizo later tagged along with the rest to save Hanzo from Kagetomo and he watched the battle between Kagetomo and Ippei.
|Saizo had a Barbaracle, who attacked Sanpei's Greninja.|
