>>6282725Yes but I don't think he's been shown killing someone in chair mode. They aren't alive in the current canon because Roberts is a hack.
The DJD had 3 torture robots on their roster. 1 turns into an electric chair,one is a mobile smelter and melts robots in in chest, and one has a massive conveyor belt and a grinder in his chest and grabby arms to shove robots through it. I guess vos, who is the sniper rifle, counts since his face comes off and drills into someone else when he makes them wear it.
