In a 100 vs 100 battle, all other things being equal, Archdevils lose only to Behemoths and Archangels... they beat everyone else.. :D
By the way, it seems to me that Behemoths will wipe out even the Archangels, and only Archdevils can take down Behemoths. And only Archangels can take down an Archdevil, and even then because of their first strike... That's a trio of the invincible!!! What do you think Kyle?
