I'm Ninja Spy... and you SUCK!
—Ninja Spy as he's about to reveal his true side and slash everybody in the face
Ninja Spy is a Spy, who's a NINJA! He's what you would call a "slice-n-dicer", because he can both slice things AND dice things. In fact, he's better at slicing than the Quick-Prep Slicer, and that's saying something.
History?[]
He used to look exactly like a RED Spy, but then he didn't look like a Spy. However unlike the spy, he does not like surprise buttsecks. His swords were blessed (cursed?) by the Demoman and thus can take endless amounts of heads which make him faster and powerfuler. He used to be friends with every bad guy and villain in existence ever, but then was reprogrammed (since he's a bot) to be a subordinate of Mr. T, and started to star in various movies like Ninjas on the Moon and is the stunt devil James Bond 007. He was almost thrown into the Wa-Machine by Mr. T to make him more powerful, but the Wa-Machine was set to Wa-Clone and not Wa-ify, so it cloned him instead.
Currently, he has taken over 30 heads thus far, but this number will exponentially grow in the future. Maybe.
