Ok, this is one of the weirdest Weird Wargamings yet, and it depends entirely on what ruleset is being used. Basically, one of my loves is “artificial humans“. The boring thing to do would be to treat them as either normal humans or robots. But there was one attempt at going beyond that.
Now in Fire Emblem: The Blazing Blade, the morphs are treated just like normal units with one exception-all of them, even the strongest, have zero luck. Zero luck means that they have lower hit and dodge rates mixed with massive opponent critical rates. That can definitely be incorporated into various tabletop rules.
Of course, it can make some sense to give them higher stats in other categories to compensate for that. It all depends on what the theme of these artificial humans are. They can be everything from super to expendable, as the Fire Emblem morphs are.
