Along with Night Ninja and his Ninjalinos, he is able to use colorful gooey balls known as Sticky Splats to pin down his enemies. He also possesses an ability known as Ninja Fingers, which gives him the power to move any object of any size with just his fingers. Despite him being the clumsiest and least skilled out of all the Ninjalinos, he is still very fast and agile.
Like the rest of the Ninjalinos, Marvin is very obedient towards Night Ninja's orders. Marvin usually stands out as the clumsy Ninjalino who is less skilled in martial arts and acrobatics than Night Ninja and the other Ninjalinos.
Marvin is identical to the Ninjazouaves and Ninjalinos, so nothing was different to his appearance.
