I wonder if there any more games i missed where you have mooks on your side and/or you technically play as one, sometimes slowly becoming more powerful and less mook-y.
Also consider to not read spoilers below. It's just autism.
Pic is not related. No bully if some thread died for this shit.
By mook i mean characters, mostly soldiers, fighters and etc., that generally being used as a minor nuisance (nowadays at least) in slasher/beat'em'up games, however they are numerous, and generally (again, nowadays) getting massive causalities because of super hero that goes on crusade to get to the boss in action-oriented games. Or they work as minor encounters and source of grind in other genres. And, of course, there's might more powerful/specialized mooks along the way.
**The examples of friendly/allied mooks are mostly Samurai/Dynasty Warriors, though they were mostly used to give battlefield feeling of happening and mostly were not advancing. Another (and the best one) is Mount & Blade, where you can upgrade your mooks, so you could conquer all Calradia for butter.
If not count M&B and EDF, where you upgrade your character to not be a mook, the example where you always play as one (except the cases where you can pick hero) would be Lord of the Rings Conquest and classic Star Wars Battlefront.**
