Tony moves onto building the ‘quick equip” suit, these kinds of suits weren't nearly as durable or powerful as ‘hard’ suits, but it still made sense to have a suit that could rush to protect him during emergencies. A suit meant to quickly defend him from threats should still be capable of handling threats on the level of an Ultron swarm, Tony can’t sacrifice too much to portability or it wouldn’t be useful in defending him.

So, he makes a suit with an improved version of the flying equip features of the old mark VII suit that he used during the battle of New York, or the XLII that he used during the fake mandarin attack. It’s as durable and powerful as as he can make it without using nanotech forging, and without being powered by a new element Badassium arc reactor instead of regular Palladium arc reactors. It blows the old mark XLII out of the water in capabilities.

As always Tony starts with better repulsors, including two back mounted ones for more stability and the ability for more jetpack style flight.

For each shoulder and ankle there are pop up tiny silenced rapid fire SMGs for emergency point defence and for when a repulsor beam or micro missile is too loud or overkill, each with a magazine of rubber rounds for less than lethal suppression.

He adds better versions of the gauntlet lasers from the mark VI with 4 spare laser emitters in each gauntlet to be cycled in for ‘reloads’ when they get burned out from use.

And as in the ‘hard’ suit, micro missiles galore, Though obviously less of them, only hundreds of them. With a bigger proportion of them being the less than lethal kind.

Tony even has plans for various different quick equip add ons that can fly towards him and be equipped as needed during combat. But for now that suit should be good enough for emergency use.

June 3rd 2009.

All this takes Tony about a month, the designing and building itself didn’t take long, but the coding and programming took ages, stuff like the calibration of repulsor flight systems software from scratch took a while, it took him six months in the original timeline and that was with much weaker repulsors. Tony also remade his missile targeting software from scratch now he had access to Jarvis and real computers.

In his spare time while waiting for code to compile and tests to finish, Tony also finished some more simple non-suit tech to keep him safe when outside of missions. Sneaky palm repulsors that could fold out from under suit sleeves, repulsor jet boots that folded out from under your suit pants, flexible chest and back armor that could hide under anything more concealing than a tshirt, micro guns that could be hidden on your belt buckle or watch, real Q level shit. Tony actually made it with personal defence in mind rather than it being meant for spy stuff, but he supposes it would make a nice present for Agents Coulson and Barton, and with some minor redesigns on the micro guns camouflage those would be a good present for Agent Romanov as well.

After all this, he finally feels ready, lets crush some Terrorists. But, Tony happens to know someone else with a grudge against the Ten rings who might want to be involved. He calls Yinsen.

"Tony. Hello, and thank you, again, for everything."

“Yinsen you pulled the shrapnel out of my chest, everything that happened was only possible because of you. So you are the guy who gets all the thanks.” Tony feels a little bashful being so emotional, but Yinsen had been the one to inspire him to be iron man in the original timeline, and his death had driven him to do that more than a little self destructively, looking back at things.

“I might be doing a special project like the one in the cave. I feel that perhaps the Ten Rings need more missiles delivered, like last time. They asked so politely for them after all. So to show my thanks, want to come help? Or just watch the feed as it happens from my very comfortable Malibu house. I know theres enough engineer in you that you will find the special project very cool.”

"I'd rather stay out of the lines of fire," he replies. "But I'll certainly want to watch this. Will your project bring you anywhere near Gulmira? If you could help what's left of my village..."

“Are they occupying Gulmira right now? I could make a stop over there.” Tony remembers an attack on Gulmira happening with a stark tech weapons shipment 5-ish months from now. That reporter gave him the pictures of the shipment during that charity ball in the last timeline. Had they been actually occupying Gulmira this whole time? Fuck, if thats true that makes Tony feel bad for spending so long building the suits.

"The area's still quite contested. It varies whether they're actively enforcing their will or just demanding money."

“Oh the area won’t be contested for long, not by them at least, and I can make repeat visits as many times as I need to until the lesson is learned.” Tony felt like he was getting a bit too dark there, lets tone that down. Not that the Ten Rings deserved any mercy, but it seems unhealthy to feel bloodthirsty. He resolves to just be excited about using power suits again instead.

“Anyway, whatever airport you are closest to I am sure I can charter a jet, come down so you can watch. I can’t wait to see what your face looks like when you see my special project.”

"I'm guessing you built a new suit of armor? And that it'll be a bit more impressive than our previous tin man?"

“And here I thought we were having fun with euphemisms. And you are damn right it’ll be more impressive. The tin man made my soul hurt it was so ugly. While my ‘special project’ should be displayed in a gallery, if the fact I make suits at all wasn’t so ultra classified, hence the euphemisms. Seriously though I can’t wait to see your reaction.”

Tony is maybe a little giddy to show off how great and smart he is and how cool the suit was. He wanted an appreciative audience damn it! And someone with some engineers spirit in them would surely react appropriately.

Yinsen nods, remembers he's on the phone, and says "Yes" aloud. "I'll be sure to watch. Good luck."

Tony sends a quick text to whatever Shield agent is his babysitter today to let Yinsen through when he arrives, and waits for Yinsen.

… Why are flights so slow, waiting sucks, It’s giving Tony ideas about repulsor using supersonic passenger planes, or at least an repulsor upgrade for his own private jet.

Yinsen will be let through by the babysitting S.H.I.E.L.D. agent. Well, definitely some sort of agent.

Rumlow will take the opportunity to make sure his superiors in HYDRA know Stark's about to attack, although there isn't much they can do about it. They've decided not to warn the Ten Rings, to avoid suspicion, and because Stark's plausibly more useful than they are, anyway. But they're certainly going to be watching this battle too.

"Hello, Tony," says Yinsen. "Is it time for your... project?"

“Yep! down in the basement!” Tony leads Yinsen to his workshop. “Oh by the way, Yinsen, meet Jarvis. Say hello Jarvis.”

"Hello, Mr. Yinsen. I'm told I have you to thank for keeping me employed."

Yinsen raises his eyebrows. "Where is he?"

Tony has the smuggest shit eating grin. He loves being able to show off. “Jarvis is the house! Or the AI that runs the house more technically. Just A Really Very Intelligent System. With my love of back-ronyms I probably should have been a NASA scientist.” Tony does have a soft spot for NASA’s tendencies for rather forced back-ronyms.

Tony smug grin gets even wider when he unlocks the security door to the workshop and the two Iron Man suits are revealed in the middle of the show car parking area. One tall and bulky and mean looking, with big miniguns on each shoulder and a steel gunmetal grey and darker red paintjob. The other slim and form fitting and showy, the hotrod red and shining gold showing off its organic curves.

"Shit. What is - how did you even - Tony, that's incredible."

Tony Points to the various parts of the suits, calling out the weapons. “The flight system is also a weapon! Ruplsors, maybe you read old papers by my dad about them. Also, high powered lasers! Rapid fire railguns! Long range missiles! Micro missiles galore! Including less than lethal ones. The big railgun! And I suppose the regular guns are worth pointing out too, but I find them a little boring. Just wait until I have miniaturised energy weapons. For armor, well, even the skinny one can tank a tank shell.”

This reaction from Yinsen is the best, Rhodey is too used to Stark miracle tech bullshit to react as well as this. Maybe Tony should make more normal friends who aren’t super spies or used to him so he can wow them like this.

”Did I mention Jarvis can remote control them? Human Pilots can react faster, but Jarvis can probably pilot them pretty well by now. I’ve done a LOT of coding for these bad boys.” Tony is the most smug engineer of all time in this moment.

”This is what I can create when not in a cave using a box of scraps, and this level of quality is only until I build even better tools.”

Yinsen just shakes his head, staring at each piece of metal on the armor. "The Ten Rings don't stand a chance."

“And when I’ve crushed every extremist group in the area, there wont be a need for my missiles. I can try and slowly undo my previous legacy, and build a new one…”

He hasn’t publicly shut down the arms production wing of Stark Industries like last time, but it has been slowly ramping down during the ‘investigation’ that Obadiah's treason triggered. Tony does need the share price to not drop as drastically as last time but he still wants to get out of selling regular arms to governments for all the same reasons as last time. Especially now he knows how much of the world governments are filled with Hydra plants that are deliberately inflaming conflict to push project Insight forward.

”It will also be a good chance to clean up any of my tech still out there. I will be already be blowing up their bases.”

Yinsen nods, a smile growing larger and larger on his face. "Thank you."

"Now go save my town."

Tony probably should use the heavier Warrior I armor for this, but he wants to show off so Tony decides to don the as yet unnamed quick equip armor. 
“Jarvis, initiate flying equip.”

The armor breaks off into parts, each part initiates small thrusters and the repulsors attached to each part to make them float, then they fly towards Tony and the trackers embedded into the bracelets he is wearing. The armor snaps into place around his body as he stands there in a T pose, just to make it easier for the armor to attach itself to him. The self equipping flying armor pieces have to be very impressive to see, and it should still be more than enough to take down a Ten Rings base.

”Open the garage door Jarvis.”

The garage door rumbles open and Tony lifts off the ground with his repulsors, damn he missed flying, before zipping off out through the driveway and into the air.

The Iron Warrior suit moves on its own and takes off after Tony, just in case Tony needs backup. Just because the quick equip suit should be enough is no reason not to play it safe.
