Jason is the main protagonist of Turning Mecard, introduced in the opening episode "New Kid, New Mystery." Brandon Winckler voices him in the English dub.
Visually, Jason stands out with his striking crimson hair and pale complexion, paired with brown eyes. His outfit is pretty distinctive: a yellow shirt layered under a red, yellow, and black striped jacket that's lined with red on the inside and has a black collar and yellow squares on the sleeves. He rounds it out with blue-gray knee-length shorts and black-and-red shoes with a black-and-white checked pattern on the sole.
Personality-wise, Jason's a good kid. He's genuinely caring with his Mechanimals and known for being helpful to anyone who needs it—even people he doesn't know well. There's a scene where he could've taken Mugan from Team Goblin after beating them, but he didn't. He also helps Dana save Dabby from Geryon's dark influence without hesitation. Basically, Jason's the type who'll go out of his way to fight evil and do the right thing, no matter what it takes.
