Tokyo Mew Mew's dub was extremely awful. Naturally because it was before 4Kids started believing their audience had an IQ-score above 5. They changed the names of the series, the characters, the original story and just about anything else they could get away with and the voice actors were terrible apart from one or two actors, and they had minor roles, sadly.
I didn't think it was possible to make a bad anime adaption worse, but 4Kids surely succeeded with their dub of Tokyo Mew Mew (AKA Mew Mew Power)
