This isn't a very common issue because you'd need quite a few molochs to even get one to drop moloch armor but I'll take the case of wishing for an emperor moloch for the exp. Eventually one will drop some moloch armor and if you lure another greater moloch over that armor and it picks it up and equips it the greater moloch becomes some sort of uber-moloch with enough speed to catch a quickling and enough hits to kill Andor Drakon in 1 turn. I have personally experienced the horrors of losing a trollish healer going for an Ultra win to one of these Uber-molochs and wish for it to be fixed.
