Would be willing to offer my hero-hunting villain for assist. Failing to kill this other hero, could just put them out of commission for a while as we try to figure out the villain's identity, motives, and how to beat them.
I know, you want me to hold off on my villain ideas. Just pictured the hero being thrown beaten onto a balcony with the Bionic Angel looking over them, warning them to stop their "idiotic PR stunt" (her words not mine) in exchange for...I was going to say their lives, but her motivations are to destroy all rank 3 and above, so probably would offer peaceful deaths. She's got a good backstory, if co-GM doesn't come back in time.
