The flashback shows the polluters' rings exploding but some smoke remaining near the ground where Captain Pollution later revives from. However, the scene was incorrect and the results couldn't have happened since in "Mission to Save Earth: Part 2", he had completely returned to the rings, which had simply exploded without a trace on the beach.
Pollution grows larger from entering into the contaminated area, but this is illogical since his counterpart Captain Planet never grows when he is rejuvenated.
