Character mistake: Another identity mistake in the finale: When Beast Boy's team is initially subdued, we see honorary Titan Hot Spot standing amongst the villains even though he is a) a hero and b) is supposed to be frozen solid at that time.
Character mistake: When Shikata disappears after she loses her powers, Peter drops the sword and he, Mary Jane and two pedestrians behind them are shown looking in the direction that Shikata was just standing in. A third pedestrian, standing to the left of the shot, can be seen but is looking in a completely different direction to the others. (00:18:37)
