Continuity mistake: In two episodes aired consecutively on CBBC on April 7th 2004, The "DON'T WALK/WALK" sign moves from one side of the crossing to the other and changes colour.

Continuity mistake: At the end of the battle between Jaden Yuki and Gravekeeper's Chief, just as the explosion settles, in one shot you see the Gravekeeper's Spear card to the left of Gravekeeper's Chief on the duel disk.

Character mistake: Professor Saotome checks the status of the Getter Robot when his son falls unconscious. The HUD output is written in awkward EngRish, from the first line of the status report, called; "Monitor the state of affairs", to smaller details like the article randomly used for certain lines ("a control device, a correspondent"). The biggest flub though is that the name of his son is "Tatsuhito", in proper romanization, but here appears as "Tatuto." (00:05:20)
Factual error: In s01e08, "Q and A", when Yelena is playing chess, we see her use the touchscreen which represents the chessboard. However, the bottom left corner is a white square when it should be a dark square. The board is orientated incorrectly, even though the board on the floor isn't.
Factual error: When the large Dutch guy tells his story about his life in Holland, there are a several windmills. However, the blades are placed on the wrong side, that way it's not possible for a windmill to turn clockwise, which it does. If the blades were placed correctly, they would still turn to the wrong side, because wooden windmills in The Netherlands are always turning counter-clockwise.
