A Technicolor Ninja is a character, most frequently some manner of costumed adventurer, who is really stealthy. Not just Badass; not just a Ninja, not just someone skilled in the Stealth Hi Bye, but so very, incredibly, impossibly, unbelievably stealthy and sneaky that neither Muggles nor Mooks will spot this stealthy individual sneaking around in their garishly colored costume. But if they do get spotted? Too bad for the spotter. Technicolor Ninjas are most frequently seen in Comic Books, Anime, and Animated Series, though it sometimes turns up in Live Action TV as well.
