Howard Cunningham

"My best friend's the Ninja! Oh, this is incredible!"

- Howard, "First Steel on the Ninja"

"Cowabunga!"

- Howard's catchphrase

Howard Cunningham is a high school student, California Ninja at Ca Frost Science Academy High, Toby's best friend, and the tritagonist of Toby and Rochelle: 9th Grade Ninja Twins. He is Stanley and Bethany's son, Delilah's older brother, Adelaide's oldest brother.

Early Life
Howard is best friends with Toby since they were kindergarten. He also has a younger sister, Delilah but they always mistaken Delilah as the older brother including Toby. This caused Rigby to be envious of his taller younger brother. Not only that, he is neglected by his parents especially by his father who always ignored Rigby or blamed him for anything bad happened.

Personality
Howard can be best described as a "wild adult", even though he is past his teenage years. He becomes frustrated, frightened, confused or sad very easily, making his behavior very predictable. Rigby is also very arrogant, impulsive, impatient and immature at times, giving him the personality of a child. Thus, he can be considered the opposite of Mordecai, who demonstrates far more responsibility and maturity than him (in most conditions). He even changed his name to Trash Boat one time because he thought it would sound cool and edgy.

Physical Appearance
Howard is a light-skinned, half-Chinese male and third main character with a height of 5'4 and the weight of 74 kg (same as Ben Schwartz), freckles on his cheeks, blonde hair, and light blue eyes.

When he was young, it was shown that he had loose tooth on the right side of the upper jaw.

Clothing
Howard is always (except as the Green Ninja) seen wearing a light black checkered pants, as well as a blue vest with a red t-shirt with a skull on it underneath, which is similar to Luna's. Unlike Luna, Howard also wears brunette boots and a white belt wrapped around his pants. He also has the same paper clip earrings Luna has.

For nightwear, he wears a lime green hoodie with a signature white "H" on the center, white pajama shorts, and pale socks.

When he was young, he wore a lime green long-sleeved shirt, gray pants, short, red socks, and light grayish blue tennis boots.
