Some scary mechas they will be adding in the upcoming event. I am already pissed off by the doppelsoldners. Hopefully these cunts don't blow you up instantly after a while.
The KCCO mecha is the Tesla Trooper, who if got close to your T-Dolls will give them a nice double electric jab.
The other from the "4th Faction" is called Roarer, also likes to bash your T-Doll waifus till they break. Worse is that it can recover it's shields every now and then.
