Now here's something I haven't done in a while. Write a silly little sidestory. Whatever happens, assume its non-canon at best and take it as a sleep deprived mind making things up as it goes along.

In The Not Too Distant Future
Next Sunday, 2076

"I told you! Man just fuckin' smashed that gonk's head with that giant fuckoff hammer of his! That was some nova shit!" The kid told the interviewer. Behind him were the various scattered corpses of various Tyger Claw members in varying states of dismemberment. Some had gaping wounds indicative of being gunned down with heavy caliber rounds, others seemed to have been beaten to death with a blunt weapon. Most likely the sledgehammer as described by the kid.

"And what about the rest of them? They don't look like they were killed with that hammer." The interviewer remarked, prodding the kid for more information.

"Well, the dude just pulled out this big-ass machine gun and started shooting them! Blam! Blam! Blam! Like one of those BDs I saw! Then we he got shot, he just threw the gun at that gonk over there," The kid explained, pointing towards one corpse that was pinned against a wall, "And then he just grabbed this bat and threw it and it stabbed the guy into the wall!"

"Wait, where did he get the bat from?" The interviewer asked, momentarily confused over what the kid had described.

"I dunno? He pulled it out of his pants I think? Or he grabbed it from one of the dead bodies lying about. I wasn't looking at how he got his weapons from. And then he just started running up and punching them. Man had some sweet chrome to let him punch their heads off like that."

"Definitely Gorilla Arms and subdermal." The interviewer muttered to themselves as he took note of that detail. "What happened next, kid?"

"Well, he just beat most of those Tyger Claw gonks into the ground and then Big Jiro came around the corner with his big fuckoff bat. You know, the one with all the spikes sticking out of it. He was a big dude, that's why they called him Big Jiro. He came around and started saying some Japanese and then the badass just told him to fuck off. Nova shit! And then he just threw a grenade at Big Jiro before he walked off. It went off right at his feet and set him on fire."

That would explain the burnt body. The interviewer thought as the kid started to wind down from his explanation of the events that transpired that led to the deaths of this group of Tyger Claws.

"Well, thanks kid. You definitely helped us out there but one more thing. How did that man dress like?"

"He was wearing some jumpsuit, had some corpo logo on it I don't know. Black boots and this big beard. Like, old geezer beard" The kid said, stretching his hands wide to display how big he belived said beard was. "That's about all I got."

"Alright kid, here's the Eddies." Ichi said, transfering the agreed upon sum to the kid. "Don't go spending it all on BDs now."

Watching the kid run off, he turned back towards the rest of Section 9 there who was combing over the place. Mainly, Motoko. Hiromi was busy asking the storekeepers there who had ducked for cover when the firefight started.

"Found anything Motoko?" He asked, being careful to avoid slipping on the puddles of blood left by this one man rampage.

"Managed to get camera footage and a name for our suspect. And this~" She explained, holding up the scorched casing of a grenade.

"Guess that matches what the kid said. Our psycho threw an incidinary grenade at Big Jiro over there." Ichi noted, gesturing towards the burnt body.

"Huh. Strange thing is I don't recognise the make of the grenade. Doesn't match any known brand." Motoko said, studying the casing. "And I don't think I've heard of any corpo called NanoTrasen before. Because if they made grenades like this, pretty sure the Big Two would've bought them right out. While the HMG he left behind had the manufacturer's brand scratched off. Someone scribbled Discount Dan on the side instead."

"And what was the name of our cyberpsycho then? He got any history we should know about?"

"Complete ghost. Databanks has no information on our mystery cyberpsycho at all. Name is Randalph P. Checkers. From what I could get from the footage, that was written on his name tag on his jumpsuit. And another tag identifying him as QuarterMaster. Weird."
