Burn, baby.

"Mobius." Afton says, approaching the scientist to see what he's doing.

"Ah! Oh!? Afton isn't it? Aha! I remember it this time!" Mobius happily exclaims.

Afton shrugs, "Err, nice job?" he mutters, shaking his head and diverting the conversation, "I'm here to see your progress on the transistors." he asks, glancing at the rather expertly done welding Mobius had just been doing.

"Hm, oh that... Yes, well, I may have run into a small pickle there..." the scientist says, floating towards another desk where what looks like bits and pieces of scrap metal are lying about. His manipulator reaches for one and drops it into Afton's hand, allowing him to see what it is.

He raises a brow, "Gold?", the transistor Mobius had just handed him was almost entirely made of gold.

"Yes! The mu-custard coloured metal... It seems to be the best suited for what you described, energy-efficient, resistant to damage... But I've been struggling with the size somewhat, getting these things to a constantly small size and shape is really tugging on my mind you know..."

Afton frowns, he wasn't even sure if these would actually be usable, "Wouldn't it be better to use silicon? Or something similar...? You can experiment further when we've actually got a few working ones."

...

"Ohh, I hadn't thought of that! Good idea! I'd almost run out of family heirlooms to melt!" Mobius says, sweeping the desk with a manipulator and causing all of the scrap metal to clatter to the floor. The trash isn't left alone long however, as the spider robots swarm in and drag it away, presumably to be processed and made ready for any experiment.

Afton sighs, he didn't know all that much about the transistors in his original world, so they were essentially working with trial and error until they find the most efficient way to operate. Looks like he'd be confined to this place while working on this with Mobius, his AI was actually almost complete, now he just needed to create the hardware for it.

Honestly, he was pretty wary about creating a skynet AI, especially with the personality he'd programmed it with. So he'd create countermeasures in not just its software, but its hardware too. This was not only to stop it from going crazy, but also to prevent outside interference. If anyone managed to gain control of his AI they'd essentially control Big Mt in its entirety, something that simply couldn't be allowed.

Afton sighs to himself, resigning to more hard work as well as many hours of listening to Mobius babble about custard and other inane topics.

A couple days later :

*CRACK!*

Afton appears outside of the Forbidden Zone Done, armed to the teeth and prepared to rip and tear Patient Zero a new asshole. On his back sat his Anti-Material rifle and Elija's Advanced LAER, on either side of his hips, were That Gun, Lucky, and two Inversal Proton axes. He had the Sonic Emitter, Sawed-off shotgun, and a Plasma pistol hanging from the bandolier on his chest.

Underneath all that he wore the typical Stealth Suit he'd almost become inseparable with, as well as a variation on the Valence radii-accentuator called the Atomic-valence tri-radii-oscillator, which was basically composed of three glowing blue rings that sat in the trademark shape of an atom.

That wasn't all however, in his hands was a large, strange device. It was shaped like some sort of minigun crossed with a flamethrower, underneath it was a huge tank that looked as if it'd take three men to carry it. Afton didn't really have an issue easily holding it up alone, however.

This, was his new creation... He took inspiration from Napalm in his old world, while in his offtime from working on the new transistor with Mobius, he'd managed to create an extremely flammable gel-like substance that clung to anything it hit.

It wasn't all that explosive, but instead burned incredibly hot for a rather good amount of time. The gas containing under it held a rather silly amount of the compressed substance, so as long as he was efficient with its use, he wouldn't find himself running out.

His mission for today? Destroy any remnants of the fungus from the crater. His main goal is to eliminate Patient Zero, so he can send in robots to do the rest... As of now, he doubted anything apart from the Giant Robo-Scorpion could fight it, and since the fungus infested cavern passages were too small for it to enter, it was left to Afton to complete the job.

He hefts his 'Ash-Maker' but doesn't immediately walk towards the passage which leads to the fungus... Instead, he started climbing the canyon to read the top. Yes, he fully intended to rain fiery death on his enemies from above.

After thirty minutes of walking Afton finally found himself looking down at the veritable sea of green below him. He tightens his grip on his weapon and checks its status via his Pipboy one last time to make sure it would work how he intended.

Nodding to himself, he glances over the cliff and spots the place where Patient Zero had been last time. The desolate and torn apart metal building that'd almost been Afton's permanent resting place.

"Take this you knock-off porn monster!" he shouts, launching a stream of liquid fire from the end of his weapon, everything under and at the end of its arc is immediately covered in a sticky flammable substance that immediately starts melting any flesh, or burning any plant matter it comes across.

The metal building in the distance takes it the hardest, the liquid fire striking the roof and slowly pooling down inside it. Undoubtedly harming anything within.

Afton holds the trigger down for a couple seconds before releasing it, taking a long hard look at his target... "Did that do it?"
