Evil Bob is a Boarder who was active roughly from 2004 to early 2005. He is the author of Agents Adrian and Rob of the Golden Sun Division in the Department of Mary Sues. Despite all the years since his retirement, he is still the only known PPCer with any GS missions under his belt.
He is also the author of The Official Fanfiction University of Alagaësia, and the one who named dragonlings as the mini of The Inheritance Cycle. While Bob himself is probably not evil, his coordinator avatar certainly is. Actually, nearly all the non-canon staff at the OFU are alter-egos of Evil Bob.
