• Sumo is a Japanese sport where a wrestler (rikishi) attempts to force another wrestler out of a circular ring (dohyō) or to touch the ground with anything other than the soles of the feet. Sumo wrestlers are always incredibly large, just like this Monster is very large.
  • In the anime, when this card detaches an Xyz Material, it absorbs it through its nose.
  • "Sumo King" sounds the same as "Smoking" in japanese. This might be related to how, in the anime, the card inhales the detached Xyz Material and then blows out a beam that causes smoke to rise when it hits.
