Jasper

Jasper is a young griffin in Sofia the First that lives in the castle jewel room along with his parents Onyx and Opal. He is voiced by Lyons Luke Mathias.

Role in the series
Jasper loves anything shiny and will take things without hesitation, making him very sneaky and mischievous. However, his infatuation also makes him easily distracted as he will mindlessly go after anything shiny. After seeing Sofia's Amulet of Avalor, he followed her and stole it. He then began stealing other shiny objects around the castle, including the Queen's new tiara, until he was spotted by Sofia's animal friends but escaped from them.

He nearly fell into a trap by Cedric the Sorcerer to obtain the amulet by baiting him with a jewel but due to a delay in Cedric's spell casting, the Griffin got away with the jewel. Cedric chased after him using a flying contraption until he crashed into the ballroom where Sofia and the guests were. Sofia realized that the Griffin was the thief and discovers him under the table hoarding the things he stole, and gets back her necklace. The Griffin is taken back to the jewel room, where the guards made sure to keep a close eye on him from now on.

He returns in "Minimus is Missing," now much bigger and more mature. His name is revealed to be Jasper, and allows Sofia to ride him when Minimus is absent. Jasper gets excited easily and flies head on into any situation without thinking it through. After helping to save all the flying horses from Wendell, he was very happy and wanted to go on another adventure. His parents commented that they would never be able to get him back in the jewel room after this.
