Continuity mistake: Seiya creates a large crater in the arena, deep enough that he has to step out of it to offer his handshake to his adversary. Cassios refuses the handshake and kicks him, making Seiya jump away. He then charges at Seiya in a straight line, as if the crater didn't exist, but when Shaina screams at him telling him to get out of the way, Cassios is exactly on the edge of the massive hole. It's as if he walked on air during his charge. (00:06:20)
Continuity mistake: Shiryu puts the medal on Seiya's chest (no idea where he found the string to craft a necklace with that). Pegasus coughs and the medal shifts a little, but not by much. The three remaining knights talk and vow to get the armor back while they leave the moribund lying there. He does not move during that, and yet when they take off the dog tag moved more to the left.

Der Aufstieg des Phoenix - S1-E6
Continuity mistake: During Nero's flashback, the right half of his head and most of his body are into the shadow after he gets hit by his sensei, but fully sunlit when the camera is behind the brute. (00:06:00)
