Here's a special bonus: Images I uploaded to my Photobucket to illustrate the visual differences between original and 4Kids versions as well as cut scenes, ordered by episode... (Some of these are so old, the pictures still have station identifications because those were the only sources available)

( Season 1 )
( Season 2 )
( Season 3 )

Back from my hiatus for the rest of 4Kids' run of Winx...

( Episode 66: Fury! / Payback )
