Deku is the hero name of Izuku Midoriya from My Hero Academia, and fan edits often restyle familiar anime characters with new themes for short form memes. Ninja Deku Dop follows that pattern, pairing the recognisable Deku idea with a stealth ninja angle that reads instantly in a few seconds. Clips like this spread through soundboards and short video edits because they need no setup, work muted as a caption joke, and can be reused for entrances, dodges and surprise reveals across anime, gaming and reaction videos.
