Card Trivia:Perfect Machine King
- This card follows a four-staged evolution:
- This monster appears in the artwork of "E.M.R.".
- In the anime, during the Virtual World arc, Nezbitt takes the form of "Robotic Knight" to act as his Deck Master. Later on in the duel, Nezbitt combines himself with "Machine King" (who "Robotic Knight" serves, according to its card text) to form "Perfect Machine King" making it the first monster to replace a Deck Master.
- This monster's stance comes from Episode 107 of the anime, when Nezbitt first Summons it, albeit a full-body version of the shot is depicted in this artwork.
- This monster's stance resembles the ending sequence of GaoGaiGar's Final Fusion.
- This monster features an "04" on its left shoulder, which may reflect Nezbitt being the fourth member of The Big Five to Duel in the anime. It may also be a reference to the Machine King evolution line, in which it is the fourth and final evolution.
