My demon army has two divsions. First, a division of classic demonic legions in red and black made up almost exclusively of DFC and Toyco figures with an oversized Mexican made Devil in command. The second division is made up of everthing else I can find that looks reasonably demonic. A good percentage of the figures I use as demons were made to be gargoyles or other monsters, but I have conscripted them all for Hell's service.
