Arise, Great Devourer of Souls! In darkness we are united. In darkness we shall rule! Arise, arise, ARISE!
~ Robert during the ritual for Ammut

Robert Frobisher-Smythe is a villain from the third season of House of Anubis.

He was Sarah's father and a great Egyptologist who was cursed by Anubis to sleep for eternity. He was awakened 91 years later by Caroline Denby, Victor Rodenmaar and Mr. Sweet, but he became evil. 

His goal is to awake the evil Egyptian godess Ammut, using the souls of five sinners.

After Ammut's defeat, Robert suddenly became older and turned to the good side.
