Jay Walker

Jay is the most light-hearted and energetic of the ninja. He is always telling jokes, most of which are only funny to himself. He usually does this to cover up fear and anxietyHe is also sensitive in both positive and negative ways and thinking. He enjoys boasting about his abilities, such as inventing and poetry, much to the annoyance of the others, but he proves to be a good friend and a skilled fighter. He is also somewhat high-strung, typically being the first to panic in dire situations.

Jay has a crush on Nya, and often stumbles on his words around her, although they both eventually reveal their feelings for each other, so now she's his girlfriend.
