Sir Percival is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She is a Mobian cat and the alternate counterpart of Blaze the Cat from an alternate universe. She is a knight in the service of King Arthur alongside the Knights of the Round Table.
Seeing Sonic the Hedgehog and Merlina teleport away from King Arthur, Percival and the Knights of the Round Table were ordered by their king to find and kill Sonic and Merlina. As Arthur left, Sir Gawain doubted his orders, but Percival and Lancelot protested that they were nothing without loyalty to the king. However, Percival admitted the king and the kingdom had changed as they left.
Holding honor in high regard, Percival is fully devoted to her duty of serving King Arthur, believing that without that loyalty they are nothing, despite having her own doubts about her king.
- Sir Percival was originally a male character in the tales of King Arthur, but for some reason, Blaze was given the role. This was probably because she is one of the series' most popular characters and there weren't many leading females in King Arthur's tales.
- Though Percival's name was never stated in the comic, Ian Flynn confirmed all the characters' names from the comic strip to be the same as in Sonic and the Black Knight.
