The Characters by in Large try to go the non-lethal route (attracts much less attention (and hardcore motivation) from KE and other Corporate types), but there are times when I've pushed to see if the monster will come out. They also have an NPC merc (Sonny) who encapsulates the trope "Good Is NOT Nice" and goes out of his way to make examples of people who make others lives miserable for his own personal giggles.
A notable bit in his background is that when the Japanese pulled out of Yomi, he led a raid to deal with the hardcore IJA, IJN troops left behind and is rather famous in the Japanese metahuman community in that they know about him, and aren't saying who or what he looks like if the Japan-a-corps come asking.
He has a severe dislike for Japanese Corps and particularly the Imperial Japanese Military and has been actively hunting in the background for troopers who had been stationed on Yomi that were subsumed into the corps. He's been leaving a trail of bodies behind him that the players are somewhat aware of (he's good enough to cover his tracks), and only recently have they become aware of his reputation as the Jiyu Senshi by his exploits in CalFree.
He had called in a favor from the players during a down time period for getting patched up. They found him in a Seattle warehouse in Tacoma that was under control of the Japanese Meta-human controlled Yakuza, (name escapes me at the moment) with an older but still physically robust Japanese gentleman bound and gagged, both pretty bloody and messy. As the groups mage medic patched him up, they asked who the guy was. He stated that he was former governor Saito of San Fran and he's been tracking him for a long time. He also stated the man had some ties back to Yomi, which was simply a tack-on from his decidedly infamous reputation in Frisco.
He also stated that he'd contact some Yomi and Frisco survivors about them man through back channels and that they were coming to thank him. Personally. I played this one calmly as after getting patched up, he had a lunch pail brought in by, what they found out to be much later to be his GF (Japanese elf with the pearly skin variation) who had been used as a "comfort woman" while she was in Yomi, as other japanese metas filtered in.
He stated he was going to send the head back to Japan and needed it intact. The rest was the survivors to play with. He put on a bit of uplifting bapitist music while the metas did to him what the Fremen did to 'The Beast' Raban from Dune, and he silently sipped his tea, smiling.
The female players were appalled as were some of the males. Sonny simply shrugged and said, "This way, no lawyer gets paid, no life sentence, no weaseling out. And some deserving people get a bit of therapy. Win Win."
The characters haven't made as much light hearted comments around him since then.
