Do you think they are willing going into to battle, armed with a rock and wearing underwear on the outside of their clothes?
You're just playing at being thick, right? Just in case, I'll be as pedantic as possible:
Having the superheroes themed units (regardless of their origin as slave or willingness to go into combat, or lack thereof) doesn't seem to address my understanding of BetaSpectre meant. What I think BetaSpectre meant, and what I was responding to, was the possibility to have "Slave Maids", "Slaves", "Slave Lashers", "Slave Gladiatrix", etc. show up as combat units in base defenses, which would be representing during the base defense all the different type of slaves that one keeps in their hideout to improve storage space. Hence my response that it would be a large amount of work, one needs to sprite all those new units, and an unrewarding project because you'd just get your slaves slaughtered without actually doing much in combat.
Hopefully that's relatively clear now?
