Originally bring back Fairy Tail Harem: Ganbarizing. But I want try something different for now.

(Yn POV)

My name is Yn Ln. Use to be like any other person living a normal life. Was inspired by Iron Man to become engineer so I'd can make cool stuff and one day build my own company.

Sheldon: Meh. Engineers.

Author: Let it go, man. Let it go.

Unfortunately died by the infamous Truck-kun! That fucking bastard! Not cool, man! Then I woke up to see a certain familiar girl in front of me.

Eris

Eris: Welcome Yn Ln. I am Eris, the Goddess of Luck and Fortune. Unfortunately I am afraid you've died.

Yn Ln

Age: 18

Height: 5'11

Yn:: Well then..............fuck.

Can't believe that is actually Eris or maybe one of the variants of Eris or I don't know whose standing there!

Yn: I blame Truck-kun!

Eris: Well....it is a menace throughout the multiverse. Anyway you have a choice. Either go to Heaven or Isekai to another world.

Thought about it. Heaven sounds good, but there's so much I haven't done yet. Plus this might be my chance to do what I've always wanted too.

Yn: Do I get any powers, armor and so on?

She nodded. Think for couple of minutes and told Eris what I wanted. My body gulf in light and dies down revealing my Infinity Armor.

Infinity Armor

Iron Man (Smirk): Sweet.

I've seen fanarts of what if Tony Stark can wield the Infinity Stones attach onto his armor. Next chose what world to go to which was Fairy Tail!

Eris (smile): Farewell and good luck.

(3rd POV)

In the World of Earthland of Earth: 768629371 where "Fairy Tail" are fighting against another guild called "Phantom Lord" with their movable fortress across Fairy Tail waters.

Ready their powerful Cannon to fire at them. Erza Titania Scarlet requip into her Adamantine Armor. The reason why both guilds are fighting each other is because Phantom Lord is hired by Lucy's father to take the blonde Celestial Wizard home by any means necessary by force.

Phantom Lord fortress ready itself to fire at them.

Erza stands and ready herself.

Erza Titania Scarlet

Age: 19

Erza: 'I will protect my friends no matter what'!

Happy

Happy: That's Erza Adamantine Armor!

Bisca Mulan

Age: 18

Bisca: Is she gonna try to block the cannon shot?!

Alzack Connell

Age: 18

Alzack: But there's no way her armor is gonna hold up against a blast that strong!

Wakaba Mine

Wakaba: You're just risking your life! This is ridiculous!

Erza: Just stay back!

Female Gray holds female Natsu back from stopping Erza.

Natsu Dragneel

Age: 17

Natsu: Erza!!

Gray Fullbuster

Age: 18

Gray: We're not gonna be able to stop her! We just gonna have faith in her!

The cannon fire straight towards Fairy Tail as Erza combines both shields and creates three huge magical crests to protect herself against Phantom Lord cannon.

Erza: !!!

Suddenly a red blur got in front of Erza while fire a blast. Powerful enough pushed it back like it was nothing! Then.....

*Boom*

The unknown beam completely destroyed the Phantom Lord cannon. Erza requips into her signature armor. Everyone confused what just happen.

Erza: What on earth?

Lucy Heartfilia

Age: 17

Lucy: Uh. Look!

Lucy pointed at a man who wears red and gold very high tech armor suit with six powerful stones.

Happy: What is that thing?!

Elfman Strauss

Age: 18

Elfman: Not sure. Hope it's on our side.

Erza: 'Powerful enough to push back Phantom Lord cannon. And it's armor....never seen anything like it'.

Within the Phantom Lord throne room is Jose wonder what the fuck is going on.

Jose Porla

Jose (anger): Who the hell is that prick?!

Suddenly what appears to be purple looking phantoms and huge magical holographic screen materialize.

Jose: How dare you?! Who the hell are you?!?

Iron Man: Me?.....I am Iron Man.

Jose: Well Iron Man. Are you here to save these pathetic Fairy Tail?

Iron Man: Yep. This can go either two ways. One: You surrender and leave quietly. Two: finish what we started to the point where I kick your sorry butt. Honestly for a guy who wears black lipstick. You don't seem all terrifying, man. Oh, I mean miss.

Fairy Tail snicker from his last few sentences while Jose has a tick mark on his head.

Jose: You'll regret mocking me, tin cane!

Iron Man has his right hand up and does his thing.

*Snap*

Iron Man dusted those phantoms as everyone was dumbstruck.

Iron Man: Was that your best shot?

Jose growls in anger.

Lucy: 'Who is this guy really'?

Iron Man turned his head slightly towards Fairy Tail.

Iron Man: I'll take care of this. Everyone can sit back and relax. This'll be over quickly.

Flies over where Phantom Lord's mobile fortress while Jose orders his Elemental Four and Gajeel to take care of him with Iron Man busted down their roof and went for superhero landing.

Iron Man: 'Huh. Does hurt on the knees a bit. Also did I see female Gray and Natsu? What's next, female Gajeel'?

Yn sees he's in a big room. Honestly he would've instantly go where Jose at. But it'll be too easy. Just wait about a few minutes until Element 4 and Female Gajeel Redfox finally showed up.

Iron Man (-_-): 'Oh you'd got to be fucking kidding me'.

Aria (blind fold), Juvia Loxar age: 18, Sun (green hair) and Totomaru

Aria: Prepare to be defeated by the Element 4.

Juvia: You'll be down by my water magic. No matter how powerful you'd are.

Sun: Don't think you'd can defeat us.

Totomaru: Burn into cinders, Iron Man.

Gajeel Redfox

Age: 18

Gajeel (Smirk): Gonna be the snot out of ya, tin man.

Iron Man ready himself to take five enemies at once.
