Erik moved to Boston and under the name Mister E he achieved some fame as both a historian and a vigilante who sought out and destroyed what he perceived to be evil.
[3] He hired a young woman recently emigrated from Dublin named Kelly O'Toole to be his assistant after she helped him defeat her former employer, Judge Kobold, who was both a werewolf and a vampire who had sentenced numerous alleged witches to hang.
Erik fought with false zombies, creatures built from corpses by mad scientists, and a leprechaun who had allowed Kelly's mother the financial opportunity to visit her in Boston.
Mister E joined Doctor Occult, John Constantine and the Phantom Stranger to teach young Tim Hunter about magic.
Mister E made the difficult decision to let Tim Hunter live in peace, thus breaking the cycle of abuse started by E's own father.
In the dead of night E broke into the homes of Russian immigrants in an attempt to find Pyotr, and threatened them with his hammer and stakes.
E's nighttime activities made the news, and John Constantine knew it had to be E, so he summoned the other members of the Trenchcoat Brigade to have a chat with him.
The Brigade won the fight and Pyotr told them they could avert the tragedy he caused if they took him back in time to the 17th century, so E complied.
E took the Brigade to the time of the Chernobyl nuclear disaster, when Pyotr's past self and Elliana of the Leshy, whose people had been destroyed by mankind, would bring M'nagalah to Earth.
[4] In the Books of Magic storyline Mister E was blinded as a child, when his deranged father gouged out his eyeballs for gazing at a woman of low moral character (his mother).
