|First Appearance||The Curse of the Golden Master|
|Voice Actor||Alyssya Swales|
Skales Jr. is a member of the Hypnobrai tribe, as well as the son of Skales and Selma. Junior was born in the Stone Army Tomb, where he resided with the Serpentine before returning to the surface following the Golden Master's defeat. During the Second Serpentine War, he and his father fought in the battle against Chen and his army.
Skales Jr. appears with his parents inside the Stone Army Tomb, being introduced to the Ninja by his father when they stumbled across the underground area. When Cryptor and the Nindroids raided the tomb, Cryptor attacked Skales Jr, but he was saved by the Ninja.
Skales Jr. has a cameo appearance with his father when Zane addressed the crowd near the Titanium Ninja statue. During the battle at the Corridor of Elders, Junior and a kid threw rocks at the Anacondrai Cultists, with Junior high-fiving the kid shortly afterwards.
Skales Jr. and his father were on the run from the Vermillion. They were attacked by the Ninja, who did not realize who they were before Lloyd tells them to stand down. After hearing Jay insult his name, Skales Jr. pushes him off of him before his father tells their reason for being down in the sewers. They, along with some Constrictai, were following Acronix and Krux on suspicion that they were using a swamp to nest the Vermillion Warriors, who are children of the Great Devourer. After his father gives the Ninja a map to the swamp, Jay apologises to Skales Jr., but he is insulted at being called "junior" and "kid" before telling his father that they should stay out of his way.
