Gregor (グレゴール, Guregōru) is a fighter at e-den fight club.
A tall and quite muscular man, he has shoulder length, wavy blonde hair and a goatee.
At e-den's underground arena, Gregor faces Klaus, but is immediately knocked away from behind by Jugglernose, a Beyondian, another participant. After being defeated, he later sees Leonardo and realizes he is with Klaus and must know Zapp Renfro. That slip, made Leonardo realize this was a set-up by Zapp and Gregor assures Leonardo that everyone will be okay. Leonardo wonders why people are gathering to see blood, when they can see it in every corner of Hellsalem's Lot, but Gregor explains that while people can easily pull a trigger and kill someone, people here are not for the blood, but for the love of the bare-knuckle combat.
