Continuity mistake: Sonic turns his head towards Mario taunting him with his shades on, and Mario's reflection is seen in the glasses.

Mario VS Sonic (Nintendo VS Sega) - S5-E13
Continuity mistake: As Mario is walking up to his lawn chair on the beach, you get a clear look at the stripe pattern on the cloth. In the shot after Sonic sneaks onto the lawn chair, the pattern of the stripes has changed. And there is much more blue area between the bottom most stripe and the wood of the chair than previously.

Nightwing VS Daredevil (DC VS Marvel) - S5-E12
Continuity mistake: As Nightwing is standing back up after using the sonic attack on Daredevil's ears, his Escrima Stick is shown on the ground glowing right by his feet behind him. But after he delivers the finishing blow to Daredevil and he begins falling over, the Escrima Stick is suddenly further away from Nightwing and in front of him behind Daredevil. It's sitting there glowing on the floor under the Screwattacks' logo. (00:17:30)
Nightwing VS Daredevil (DC VS Marvel) - S5-E12
Continuity mistake: Nightwing and Daredevil square off against each other as the word fight appears on screen. In the next shot as they start to run at each other, they are suddenly further away. This is most notable by Daredevil as in the previous shot he was standing almost right on a line in the floor that was leading to some car part boxes. But in the shot of him running he's suddenly a few feet behind this line and not to it yet. (00:14:45)
