Landfall

A bright flash of light, and in the summoning circle stood figure in red and gold armor.

"Are you my master?" The figure spoke "No wait, let me guess... It's the hot girl with purple hair!"

"...Y-yes, I am your master." Sakura Matou replied in surprise at the greeting from her servant. "May I know your class?"

"Servant Rider at your service." The figure took an extravagant bow before stepping and standing behind Sakura. "I'm sure we'll work great together!"

"Of... Course."

-]l[-

"You want to give me to your douche bag of a brother cause you don't want to fight? What kind of bad reasoning is that, c'mon, he's almost as much of a douche as I am, like that decision is almost as bad as Strange deciding to give the time stone up to Thanos... Ah whatever, who am I to argue with such a pretty master like you."

-]l[-

"For the record, I'm sorry about doing this to you kid."

Shirou Emiya turned his head as fast as he could, but all he could catch was a red blur before he was knocked out via a blow to the head.

Taking a moment to chuckle at the teens misfortune, Rider quickly raised his head. "Who's there." Rider questioned seemingly the air, before suddenly leaping backwards with added momentum from his jets to dodge a swing of an invisible blade wielded by a swordswoman in blue.

"So your sword is a bit over four feet long and shrouded in wind... Hmm, I wonder how you managed that one, magic I bet."

"You would be correct in your guess. I am servant Saber, may I have your class?" The newly named Saber questioned her opponent.

"Servant Rider at your service. Shall we fight?" Rider crouched down to the ground before rocketing towards Saber at high speeds where they engaged in a series of blows, the sword shrouded in wind against blades that Rider had projected out of his arms.

Saber mantained a range to Rider whereas Rider continuously attempted to close distance to make use of his much shorter blades. This continued for a few seconds before a pause in the battle had Rider moving back away from saber.

Raising one arm, Rider pointed a closed fist at Saber, before the armor seemed to flow around his fist forming a large cannon pointed at Saber.

Saber's eyes widened as she leapt out of the way of a large blast of bluish white energy flew past her and destroyed a swath of land behind her. Saber wondered how her B-rank magic resistance would stand up to a shot like that. Turning to face her opponent Saber found Rider disengaging the cannon, and turning to run away.

"Sorry love, but my master seems to have gotten into a small bit of trouble at the hands of a magus. Gotta run!"

With that, Rider blasted off the ground and spiraled into the air before leveling out and heading straight towards his master.

"What a strange Rider. Better than Iskandar at least."

-]l[-

Tony Stark stepped through the Matou mansion as he looked for his master -both of them. Tony wasn't wearing his armor currently, though it was inside the arc reactor attached to his chest.

Stepping through a hidden door Tony found himself at the top of a long stone staircase that led into the darkness. Walking down it Tony mentally used a part of his armor as a floating flashlight next to his head.

As Tony got closer to the assumed bottom of the stairs, the area became clearer as well as a very quiet sound of somethings skittering.

When Tony finally reached the bottom, he found a stone pool in the ground, and laying in the center of it was his summoner. Surrounding her and even crawling over and into her was a large amount of worms that covered the entire floor of the pool.

Taking a closer look at his summoners eyes found Tony staring into a set of dead orbs that didn't seem to be focused on anything, and the occasional flashes of pain going through her body causing her to flinch.

"Friday, scan the girl." Tony spoke quietly to his AI as he looked towards the girl.

"From what I can gather, these worms seem to work as artificial magic circuits, and they are implanted within Sakura's body. They seem to feed off carnal urges. I hypothesize that she has been in this pit every night for many years, possibly since she was a young child."

"... Damn, I really can't just do nothing about this now can I."

Tony tapped his chestplate twice in quick succession to activate the armor, before stepping forwards and picking Sakura up. She immediately stiffened and looked at Tony whose helmet was still down to reveal his shades.

"... No... Grandfather won't let me leave." Sakura spoke to him even as he carried her up the stairs and out the building.

"You just let me worry about that alright Sakura? You are my real master after all. It only makes sense that I would save you from that if I can."

"But you can't." Sakura seemed unwilling to accept that there was any way to escape from her torture.

"I already told you I could do it. Just trust me, Master."

"... Alright..."

"Good, Friday activate the bombs in Shinji's book would you?"

"Gladly."

Tony walked out of the mansion holding Sakura as a few small explosions went off within the mansion.

-]l[-

Tony was up through the night scanning Sakura, and after almost four hours, he had an idea on how to remove the worms from within her body.

"Alright Friday, you ready?"

"Of course."

"Wonderful." And with that, Tony lowered his hand to Sakura's chest where the armor he was wearing on his chest flowed down his arm, before covering Sakura's body and disappearing, seemingly under her skin.

For a brief moment Sakura seemed to glow with faint blue light, before the armor flowing back into the storage unit on Tony's chest. Satisfied with the operation Tony grabbed Sakura in a princess carry and began walking.

"Friday, calculate course to Shirou Emiya's house."

-]l[-

"Kid, are you seriously this dense?"

"Huh? Whadya mean Rider?"

"You're in the middle of a love-triangle, but it seems like you're on another dimensional plane entirely with how much you notice it."

"What?"

"...I give up on you kid. Maybe your girlfriends will be able to beat some sense into you by the time you're my age."

Servant Rider and Shirou Emiya were both currently sitting in the living room while Sakura,, Rin, and Saber planned how to best assault Beserker.

Just as Shirou was opening his mouth to deny that they were his girlfriends, said females proceeded to walk into the room where Rin stood in the center to relate the plan.

"So this is what we're going to do..."

-]l[-

"Gate of Babylon!"

"This is so bullshit. Why do you get an unlimited number of swords to fire at me? What kind of overpowered Noble Phantasm do you have anyways? You gonna pull out Cap's shield and Mjolnir next?"

Rider's rant was cut off as a blade came flying at him. Flipping over it, Rider leapt back before calling out his own Noble Phantasm to try and counter Gate of Babylon.

"Iron Man Armor. MK. XLIV: Veronica!"

"What do you think you can possibly do against my majesty, mongrel?"

"Well... for starters, I was hoping that I'd be able to get you to shut up, but if that seems like too much then I guess I'll just have to punch you into silence." Rider stepped back as faint whirring was heard in the nearby area. Smirking at the lack of Noble Phantasm from Rider GIlgamesh deactivated his gate as he waited for Rider to try something.

Just then, the sound of rockets activating filled the air, and large pieces of a red armor flew towards the ground and at Rider. Rider floated a few feet in the air as the pieces attached to him, and withing seconds a larger armor was standing in Riders place.

"Alright Everybody. Stand Down."

The Hulkbuster rocketed forwards towards Gillgamesh with its boosters activated. Eyes widening as the fist came towards him, GIlgamesh covered his face with his arms to cushion the blow.

Flying nearly fifty feet back GIlgamesh spit out blood before filling the sky behind him with a massive number of golden ripples in the air.

As Rider began charging at him, Gilgamesh pulled his mental trigger on the gate, and released hundreds of prototype Noble Phantasms towards Rider's towering armor.

The Hulkbuster armor was battered by the weapons, and the explosions continually knocked the armor back before finally exploding and destroying the armor.

From the smoke rocketed the smaller armor juking between the weapons and flying at high speeds towards Gilgamesh. The armor flowed through the air, and formed a large booster around the feet to immediately boost Rider towards Gilgamesh at mach 2.

"Sit, mongrel."

A blast as large as a small house engulfed the armor, and Rider was sent flying from the blast sans armor.

Everyone watched as the man in the suit landed in a slump against the wall before forcing himself up. He opened his mouth to speak.

Iron...

Gilgamesh raised an eyebrow as he heard the power in the word. Readying hundreds more portals to the Gate of Babylon Gilgamesh readied himself for the assault.

Legion!

Hundreds of armors of similar design to the one that Rider had just been wearing appear out of thin air, flying in on jets to land next to Rider, who raised simply stood there watching.

Red armors, silver armors, black armors, blue armors. Even a couple more of the larger armors that Rider had used previously were floating there next to a massive three story tall armor.

"Behold, my life's work. Every single suit that I've ever made. Built for every occasion, I've fought gods in these suits. So you know what? I am Iron Man."

And with that Tony Stark stepped forwards as the MK XLVII surrounded him, and took a running start to begin flying at Gilgamesh alongside every other suit with him.

Everything I've done, everything I'll do today, everything I'll ever do, I do to protect this world. [...] When I put on this armor, I took on more power than any human was ever intended to have... and maybe more responsibility than my heart can truly bear. But today... I will do my job. I will protect you. No matter what it takes...
