so, i shouldve thought of this earlier. we have the love puppy, mewkat, impostucube, all monsters that have a lox chance of appearing in place of another monster. but i think there should be a substitute monster for every monster family, for example, fiends. a "fired devilite" has a low chance of appearing in the place of a given devilite. the fired devilite no longer works for undercorp, and will not attack you. it does however, have a special drop, like the other substitute monsters, i just dont know what that drop should be yet.
