Yes. That was already mentioned earlier in the thread (see Matthew Williams' post). The changing of the team leader's name from 'Buzz' to 'Ace' had nothing to do with fan complaints, however: the name was changed because a Dutch freelance illustrator named Metin Seven had already copyrighted a character named 'Buzz Bunny'. In any event, the character redesigns didn't help, though. In fact, the characters' looks were the least of LU's troubles.
