Ninja Dave (voiced by Erik Bauza) is a character from Dan Vs. He is a former ninja and the creator of Ninja Dave's cookie shop.
He is a determined and focus young man.
For nearly the entire Ninja episode, Dave is in his traditional Ninja garb similar to Elise's.
At the end of the episode, and every appearance after that, Dave sports a red t-shirt with his shop's name, blue jeans, and green and white sneakers. He also wears a little paper hat pictured with a cookie.
His hair seems typical of Japanese youth (specifically the "deliquent-type"), with the sides and back kept short or shaved off and long with a wild frontal style.
Dave first appeared in "The Ninja", where he attempted to assassinate Elise for becoming a rouge. Elise defeated him, who then surrendered. He then revealed to them that his entire ninja clan was wiped out in a bus accident.
Dave redeems himself and opens a cookie shop called "Ninja Dave's" in the city and offers Dan, Chris, and Elise cookies.
