Khepri (Egyptian: ḫprj, also transliterated Khepera, Kheper, Khepra, Chepri) is a scarab-faced god in ancient Egyptian religion who represents the rising or morning sun. By extension, he can also represent creation and the renewal of life.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
