Underground

It was a nice quiet winter in the land of the monsters.

Undyne, a tall female fish woman stood back as Papyrus, a tall lanky skeleton said.

Papyrus: You know Undyne, I never really like flowers. Especially the ones that talk.

Undyne raises an eye brow and she questions.

Undyne: Huh? Flowers that talk?

Deadpool peers out and he points at a yellow flower saying.

Deadpool: Talking about that one.

Flowey denies.

Flowey: Nuh uh! I can't talk.

Pinkie Pie dumps a cow dung over him and she said.

Pinkie Pie: Here, have some fertilizer.

As Deadpool and Pinkie Pie left, Flowey thought beneath the turd.

Flowey: Soon, I will show them the meaning of pain!

However, Flowey growls as he heard Deadpool shouting back.

Deadpool: Don't quote Akuma!

Outside

Papyrus said.

Papyrus: Yeah I....wait a minute.

Papyrus began looking up, causing Undyne to question.

Undyne: What is it Papyrus?

Papyrus answers.

Papyrus: There's something falling. It seems to be getting closer....

Without warning, something slams into Papyrus, causing Undyne to wince.

Undyne looks down and she saw an armoured man pushing himself up.

The man questions.

???: Uh....where am I?

Papyrus got up with his head set ablazed and the man said.

???: Oh sorry Ghost Rider, didn't see you there.

Just then, Undyne shouts at him.

Undyne: Hey you punk! How dare you hurt my friend?!

The man stood up and he said.

???: Look lady, I didn't see him there. I even apologized to him. By the way Ghost Rider, didn't know you are into fish.

Papyrus stares at him and he questions.

Papyrus: Who's Ghost Rider?

Elsewhere

Johnny Blaze is just seated down cleaning his motorcycle when a young pretty woman approaches him.

Johnny turns and he smiles at her.

Johnny: June Moone.

June smiles amd she said.

June: Hello, you must be Johnny Blaze.

Johnny: I sure am.

As the two smiles at each other, all of a sudden, June gasps and she pushes Johnny back, causing his eyes to widen.

Johnny questions.

Johnny: Hey what's wrong?

June gasps in pain as green dark energy began engulfing her.

June: She's....here....run!

June screams as a female figure cladded in a witch outfit pushes out of her back and she said to Johnny.

Enchantress: June's all mine Johnny.

Johnny eyes began glowing and he grunts in pain before he lets out a mighty scream, causing his entire body to set ablaze.

Enchantress watches as Johnny's head became a blazing skeleton.

Johnny has become the Ghost Rider.

Ghost Rider said to her.

Ghost Rider: Your victims demands vengeance and you shall suffer for it!

Enchantress said to him.

Enchantress: There is no one who could punish Enchantress

Enchantress and Ghost Rider glares at each other before the two charges forward.

Now

Undyne launches a barrage of spears at Iron Man, causing him to fly back.

Iron Man dodges the spears before firing several plasma blasts at her.

Undyne summons a spear into her hand and she hurls it at Iron Man.

Iron Man dodges the attack and he laughs.

Iron Man: Ha ha! Missed me!

However, the spear flies back and it struck Iron Man by the back, knocking him down.

Iron Man screams as he fell down onto the ground.

Undyne looks down and she shouts.

Undyne: Defend yourself!

Undyne swung down her spear.

However, Iron Man activates his energy blade, blocking the attack.

Iron Man fires his propeller from his jet boosters, blasting Undyne back.

Iron Man flies up and he fires a missile at Undyne, blasting her back.

However, Undyne recovers and she launches several arrows at him.

Iron Man activates his energy shield, blocking the attack before firing a barrage of missiles at her.

Undyne punches the missiles back towards Iron Man, causing him to widen his eyes in shock.

Iron Man curses.

Iron Man: Oh crap!

KABOOM!!!

The missiles struck Iron Man, blasting him back.

Iron Man screams as he crashes back.

Papyrus looks up and he compliments Undyne.

Papyrus: Wow! Great job Undyne.

Undyne smirks and she bragged smugly.

Undyne: This is why you should never mess with the Royal Guard.

However, without warning, something flew towards Undyne at super speed, slamming into her.

Undyne screams as Iron Man rams her through several trees before grabbing her and throwing her into a rock.

Iron Man charges up a chest blast and he fires at Undyne, blasting her back.

Snowdin Inn

Sans the Skeleton is sitting in the inn, talking to Pinkie Pie and Deadpool.

Pinkie Pie questions.

Pinkie Pie: So, what do you want exactly?

Sans answers.

Sans: Oh I dunno, hopefully Iroha might let us see the surface.

Suddenly, something blasts through the inn, shocking the three.

Sans stares at the blast and he questions.

Sans: Undyne is that you?

Outside

Undyne screams as she slams backfirst into a rock.

Undyne groans as she collapses onto the ground.

Iron Man lands in front of her and he remarks.

Iron Man: Well, looks like the fights over.

Iron Man readies his proton cannon, ready to finish Undyne off.

However, Undyne's mouth twisted to a smile, causing Iron Man to widen his eyes.

Iron Man: Wait what?

All of a sudden, Undyne puts her hands upwards, conjuring a massive circle of spears around him.

Undyne swung her arms inwards, slamming the spears into Iron Man.

Iron Man screams as he fell onto the ground.

Undyne summons another circle of spears and she launches them at him.

However, Iron Man flies up and he charges up his Proton Cannon.

Realizing that it was too late, Undyne curses.

Undyne: Oh shit!

Iron Man: PROTON CANNON!!!!

Iron Man launches a powerful blast at Undyne, causing a massive explosion.

KABOOM!!!!

Smoke billows around the area and Iron Man remarks.

Iron Man: Well glad that's over.

However, as the smoke clears, Iron Man widens his eyes in shock as he saw Undyne kneeling on the ground.

She's covered in scratches and her strength and energy has been spent, but she's still alive.

Undyne suddenly bursts into laughter and she said.

Undyne: Ha ha! That was fun! Thanks for the workout tin man!

Iron Man said to her.

Iron Man: Firstly, my name is Iron Man. Secondly, yeah...you're right. That was fun.

Both Undyne and Iron Man stares at each other before the two bursts in laughter.

Undyne compliments Iron Man.

Undyne: You sure are strong.

Iron Man returns the compliment.

Iron Man: So are you.

As Undyne stood up, she questions Iron Man sternly.

Undyne: Listen, there us something I need you to tell me....

Feeling rather uneasy, Iron Man questions.

Iron Man: And that is?

Undyne continues by asking.

Undyne: Is anime real?

Iron Man answers.

Iron Man: Of course they are real. They're literally everywhere.

Upon hearing that, Undyne jumps up and she shouts excitely.

Undyne: Yes! YES!!! I knew it! Magical girls! Giant swords! Here I come.

Just then, Iron Man turns and he saw Papyrus, Sans, Alphys, Asgore, Toriel, Muffet and Mettaton approaching them and Toriel questions.

Toriel: Dear stranger, do you know how to help us reach the surface?

Iron Man smiles and he answers.

Iron Man: As a matter of fact, I do.

Within seconds

Iron Man flies out, carrying the monsters with him and he said.

Iron Man: Here we are.

As the monsters looks at the sun, their eyes widens in intrigue.

Alphys: It's....beautiful.

Asgore agrees.

Asgore: Yeah. I haven't seen that in years.

Papyrus loudly declares

Papyrus: Alright! Let's go people!

With that, all the monsters began running out.

Iron Man turns to Undyne and he offers.

Iron Man: Hey, why don't you come with me? I'll take you to Japan where you can see all your anime.

Undyne questions.

Undyne: Really? You mean that?

Iron Man nods and Undyne shouts excitely.

Undyne: Then what are we waiting for? Let's go!
