so this is the character - DLC03AFBFight02BoSGunFodder01

i can't find the base id... i want to spawn him ingame

xx005C4F

Replace the xx with the load order of Broken Steel. For example, if it's the third mod in the load order, use 03

For future reference, to see the base forms in the Geck, you may have to drag the column headers over a bit. The form ID column is just to the right of the Editor ID, but that column may be too thin to actually read.
