|This article is about a/an monster in Shuriken Sentai Ninninger.|
Created by Masakage Tsugomori when an infected Sealing Shuriken fuses with a payphone, Yamabiko was tasked to steal the Transformation Nin Shurikens from the Ninningers to render them powerless. While he had successfully tricked Takaharu into giving him four Nin Shurikens, what was left is ShiroNinger's, which he tried to trick Fuuka but goes a little awry. As Fuuka arrived, she discovered the whole trick after witnessing her siblings and with StarNinger tried to attack Yamabiko to regain the stolen Shurikens. After unsuccessful pitfall techniques, she fells into one but uses it to reclaim back the Nin Shuriken, allowing the others to transform and finish Yamabiko.
Yamabiko was grown by Kyuemon Izayoi and tried to incapacitate the OtomoNins with his loud scream but countered by Wanmaru's howl and in the end killed for good by Shurikenjin and BisonKing.
Yamabiko was among ten Yokai who appeared alongside Kyuemon Izayoi and the Western Yokai Wolf Man to Kinji in his vision after he had transformed into reincarnation of the Wolf Man, all bearing his face. When Kinji overcame his fear and doubt, and thus his Yokai side, he used the Demon Sword Urasame to vanquish all the illusionary Yokai and return to the real world.
Yamabiko's likeness appeared among a set of Yokai karuta cards assembled by Shurikenger for the Ninningers to analyze the Yokai they had defeated so far. Through the power of Yokai Fudagaeshi, Fuuka, having been made to accidentally pick the wrong card, was sent to a pocket dimension within Yamabiko's card where she was forced to face him again. She was aided by Nagi, who followed her to the pocket dimension by deliberately picking the wrong card. Together, they destroyed Yamabiko with their combined High Schooler Violent Slash attack, thus freeing them from the karuta card.
