UPDATE: The name I just found out of is B.J. Blazkowicz III; According to DOOM RPG's story, the game pit's you as the same Space Marine as the other games (EXACTLY the same as Doomguy.), and that he travelled time to kill more hellish entities as a Praetor like Super Soldier. All these roles share the same role as DOMM RPG Doomguy, thus it would be assumed Doomguy's true name is B.J. Blazkowicz III

That is all...
