## The Analytical Stand-off
"You are Jack," Genos stated, his voice a mechanical monotone. "Sensei mentioned you. He said you were the only one who could keep up with his morning squats without coughing up a lung."
Jack leaned against the railing, looking at the intricate, heat-pitted plating on Genos's shoulders. "Squats are the easy part, kid. It's the 'not losing your mind' part that's hard. I see you've already had a rough day. That left elbow actuator is dragging."
Genos looked down at his arm. "A minor skirmish. Dr. Kuseno will repair it. Why do you look at me as if I am a collection of spare parts?"

## The Pitch: Science Meets Mystery
Jack reached into his pocket and pulled out a small, hexagonal disc—the **[Integrated Weaver's Patch]** he'd just crafted.
"Because," Jack said, tossing the disc to Genos. "Your doctor builds great hardware, but he's limited by the materials of this city. I'm not."
Genos caught the patch. His internal scanners immediately flared red.
> **Scanning...**
> **Composition:** Unknown Titanium-Derivative.
> **Energy Trace:** Non-thermal radiation detected (Faint).
> **Warning:** Biological signature detected within metallic lattice.
"What is this?" Genos asked, his optics glowing brighter. "It feels... alive."
"It's a prototype," Jack explained. "Slap it on that damaged elbow. It uses a bit of stabilized energy to reinforce the structural integrity of the joint. Consider it a gift from a fellow 'student' of Saitama."

## The Internal Chat Reaction
While Genos processed the gift, Jack's chat panel flickered in his peripheral vision.
**Tony Stark:** You're giving the kid the prototype already? I hope you didn't leave my signature on the lattice. I don't need a lawsuit from a different dimension.
**Momonga (Admin):** Be careful, Jack. That 'cyborg' is a bundle of sensors. If he detects the mana traces in that patch, he may conclude you are a monster rather than a human.
**Jack:** (Mental Reply) Relax. He's too focused on Saitama to care about the 'how.' He just cares about the 'results.'

## The First Bond
Genos hesitated, then pressed the patch onto his sparking elbow. The alloy hissed as it bonded to his plating. The dull ache of the stressed metal vanished, replaced by a strange, cool stability.
"The efficiency of my joint movement has increased by 4.2%," Genos muttered, his eyes wide. "How did you achieve this? No laboratory in City Z has this signature."
"I have friends in low places," Jack smirked, nodding toward the apartment door. "Now go on in. Saitama's watching a sale on cabbage. If you want to be his disciple, you'd better start learning how to read a grocery flyer."
Genos bowed stiffly. "I will analyze this gift further. But for now... I must seek the path to strength."
As the cyborg walked inside, Jack looked back at his screen. The "Genos Data" was already being uploaded to the Crafting System.
**Jack:** (Typing) Alright, Tony. The patch worked. Now, let's talk about those **[Repulsor Stabilizers]**. I think we can make Genos's Incineration Cannons actually hit their targets without melting his own chassis.
**Tony Stark:** Now we're talking. I'll trade you the stabilizer math for a sample of that kid's 'Core Fluid' once you get it. I want to see how his doctor handles heat exchange.
The air in the chat room was already buzzing with the technical debates between Stark and Jack, occasionally punctuated by Momonga's grim tactical interjections. Then, a new notification flared in a bright, energetic gold.

### **[Interdimensional Chat Group]**
**System:** *User 'Goku' has joined the group.*
**Status:** *Connected.*
* **Momonga (Admin)**
* **Tony Stark**
* **Jack**
* **Goku**
---
**Tony Stark:** Oh, great. Another one. Let me guess: "Goku." Sounds like a brand of high-end vitamins. Please tell me you're a pacifist scientist. We have a shortage of those around here.
**Goku:** Whoa! Is this some kind of telepathy? King Kai, is that you? Wait... I'm reading this on a floating screen. That's neat! Hi everyone! My name is Goku. I heard there are some strong people here?
**Momonga (Admin):** "King Kai"? Telepathy? Your entrance lacked the usual dimensional distortion signatures, Goku. And your energy reading... even through this interface, it feels like I am staring into a collapsing sun.
**Jack:** (Smirking at his screen in City Z) Welcome to the circus, Goku. You're looking for strong people? You definitely came to the right place.
**Goku:** Really?! That's awesome! I was just training in the mountains, but I'd love to spar with you guys. Though... Tony, you smell like metal and oil. Are you a robot? I fought some Red Ribbon robots before, but they weren't very chatty.
**Tony Stark:** "Smell"? He can smell me through a multiversal text channel? Jack, what kind of neighborhood are you pulling these recruits from? This guy's "vibe" is making my sensors redline.

### **The Collector's New Target**
Jack leaned back, his mind racing. *Goku.* The gold standard of limit-breaking. If Saitama was the "End Point" of strength, Goku was the "Infinite Progression."
**Jack:** (Typing) Hey Goku, I live with a guy who's probably a lot like you. He's looking for a challenge, too. But tell me—what do you eat to keep up that energy?
**Goku:** Oh, everything! Fish, pork, dinosaur tail, heaps of rice! Why? You hungry too?
**Jack:** Always. Tell you what, I'll send you some of my world's "Special Grade Monster Jerky." It's packed with calories. In exchange, maybe you could send me a few of those "Senzu Beans" you mentioned earlier? I'm a bit of a gardener.
**Goku:** Senzu Beans? Sure! I've got a couple left in my pouch. They taste like old fish, but they'll fix a broken rib in a second! Sending one over now!
---
### **The System Check**
**System:** *Item [Senzu Bean] received. Scanning...*
> **Analysis:** High-density life-force concentrate.
> **Potential:** Can be refined into **[Serum: Instant Cellular Restoration]**.
> **Warning:** Biological energy exceeds current "Crafting System" stability limits. Requires **[Mana Stabilizer]** from Momonga and **[Bio-Filter]** from Stark to process safely.
**Jack:** (Typing) Momonga, Tony—I'm going to need your help processing this bean. If we pull this off, I can craft something that'll make sure none of us ever have to worry about a "combat injury" again.
**Tony Stark:** A magic bean. Of course. Why did I think this week would be normal? Fine, I'll send the filter specs. But I want a biopsy of that "Dinosaur Tail" Goku mentioned. For... research.
**Momonga (Admin):** An item that provides instant restoration without the use of [Tenth Tier] healing magic? This Goku is a fascinating addition. Very well, Jack. Let us see if we can synthesize the power of a "Saiyan."
**Goku:** A "Sigh-an"? How'd you know what I am? This group is so smart! Hey, Jack, does your neighbor want to spar later? I'm getting fired up!
Jack leaned back in his desk chair, the glow of the holographic panel illuminating a sharp grin. The timing was perfect. He needed to gauge exactly where this version of Goku stood on the power scale to avoid a catastrophic "miscalculation" if the Travel function ever got used.

### **The Interrogation**
**Jack:** Glad to have you, Goku. To get everyone up to speed—where exactly are you right now? And who was the last guy that really gave you a hard time?
**Goku:** Oh, I'm on a planet called Yardrat! I'm waiting for my ship to get fixed. The people here are great, and they're teaching me some really weird tricks. As for the last fight... man, that was a tough one. It was this guy named Frieza on Planet Namek. He was way stronger than anyone I'd ever seen. I had to turn into a "Super Saiyan" just to keep up!
**Tony Stark:** "Super Saiyan"? Is that a transformation or a marketing slogan? And "Planet Namek"? Jack, is your neighbor the *only* one on Earth, or are we dealing with a galaxy-trotting martial artist here?
**Momonga (Admin):** Yardrat... Namek... These locations are not in my archives. But the term "Super Saiyan" carries a significant weight of energy. Jack, you seem to have an internal dossier on our new friend. Care to share?
---
### **The Assessment**
Jack pulled up the private group sub-channel, excluding Goku for a moment so he could speak freely to the genius and the strategist.
**Jack:** Listen closely. Goku isn't just a "strong guy." Post-Frieza, he's a planetary-scale threat.
**Tony Stark:** Define "planetary." Like, he can take over a country?
**Jack:** Like, he can erase the crust of the Earth with a concentrated beam of his own life force if he loses his temper. His "Super Saiyan" form is a biological multiplier. It takes his base stats—which are already enough to juggle tanks—and cranks them up fifty-fold.
**Momonga (Admin):** Fifty-fold? That is... mathematically absurd. Even with [Maximize Magic], the scaling shouldn't be that linear.
**Jack:** In his world, it is. But here's the kicker for us: his body is a biological battery for a type of energy called "Ki." Unlike Saitama, who is just a physical wall, Goku's strength is a mix of muscle and spiritual pressure. Tony, if we can figure out how his cells store that much "Ki" without vaporizing, we could revolutionize your power cores.
**Tony Stark:** A biological reactor that scales x50 on command? Okay, I'm interested. But how do we keep a guy like that from accidentally sneezing and leveling a continent?
**Jack:** He's a good guy. Obsessed with food and fighting, but zero malice. Momonga, those "Senzu Beans" he has? They are essentially a "Full Restore" in a legume. No Tier cooldown, no mana cost.
