Simon is seen fidgeting with his Omnitrix in a private jet next to Tsu. In the seats across from them were Midoriya and All-Might.

Tsu: Oh, hey. I think I can see I-Island!

Midoriya climbed over his two classmates and excitedly pressed his face up to the window.

Midoriya: Wow! The floating city that can move anywhere! Home to over 1,000 scientists!!!

He then realized he was climbing over Simon and Tsu, quickly sitting back down.

Midoriya: S-Sorry!

Simon: It's fine dude. Geez, you sure are excited about this huh?

Midoriya: Of course I am! I can't believe you managed to get us away from training for this All-Might.

All-Might: Well, me and Tennyson did capture one of the world's most dangerous villains.

Tsu: I'm just glad they let you bring me and Midoriya along ribbit!

Simon: Not like they were gonna say no. Imagine that? "Hello number 1 hero and the kid who teamed up to defeat that crazy villain! Come to our island! What's that? You wanna bring two extra guests? Good heaven no!"

He chuckles to himself.

*ding*

Intercom: Attention passengers! We will now be arriving at I-Island!

All-Might, this is gonna be exhausting.

He sighs.

All-Might: I'm gonna have to maintain my muscle form while we're there. Gotta keep spirits high after everyone saw me shrivel up like that.

Simon: Want me to go Overkill again?

All-Might: no, I'm good. It'll just be a little exhausting.

He sighs.

All-Might: Now, you three get your hero costumes on! You've gotta look your best for the cameras!

Later—

Now all in costume and All-Might in his muscle form, the group of four are pushed along a conveyor belt-like entrances path.

All-Might: Time to test your trivia! Why was this artificial island created?

Before Simon or Tsu could begin to think of an answer, Midoriya spoke up.

Midoriya: I know this! It was built so the world's brightest minds could father together and research quirks, semblances, aura and more to make hero support items! They made the island moveable to protect it from aquatic Grimm and villains! It's got a a security system on par with the one at Tartarus Prison, so basically no one has ever committed a crime here!

All-Might: Way more than what I was expecting but that's expected from you young Midoriya! Hahaha!

The machines scan the four, confirming their identities before letting them in. They're brought into the massive and advanced island that Midoriya, Simon and Tsu take a second to marvel at.

Tsu: I can't believe so many people showed up before the expo opened to the public!

Simon: Damn, looks like an amusement park!

Midoriya: No way! The pictures of this place don't do it justice!

All-Might: Unlike back in Vale, people are allowed to use their quirks however they wish on this island! The pavilions are jam-packed with attractions and demonstrations, you three should make some time for them later!

All 3: Got it!

All-Might looks at a device in his hands.

All-Might: Now let's see. The hotel should be near by...

Simon noticed a person in uniform come up and approach them.

Employee: Hello! Welcome to I-Expo!

They had a moment of realization, now able to get a good look at the group.

Employee: Is that you All-Might and your transforming student from TV!?!?

Several other people, apparently also only realize now, all get excited and crowd around them, causing Midoriya and Tsu to get lost in the swarm.

All-Might: Thank you all for the warm welcome!

Simon: T-Too many people!!!

All-Might: This is what it's like being famous young Tennyson! Now, everyone form a line and we can start signing autographs!

After a bit, the crowd finally dispersed enough for Simon to escape, but not unscathed. He now had messier hair, crooked goggles, lipstick marks all over him and a red face from embarrassment.

Simon: I feel so dirty!

Tsu: You okay ribbit?

Simon: I-I'm alive.

Tsu: Here.

She stuck out her tongue and used it to wipe away all of the lipstick marks.

Simon: Phank Chu...

All-Might waved goodbye to the fans before walking back over to the students.

All-Might: Didn't expect that to take as long as it did. I'm afraid at this point we're in terrible danger of being late!

Midoriya: Late to what?

All-Might: Ah! I wanted to drop in and surprise a deer old friend of mine I haven't seen in a good while! Sorry to spring it onto you three but would you mind accompanying me?

Midoriya: I get to meet one of All-Might's friends!?!?!?

Simon; I don't see why not!

Tsu: Sound good, ribbit!

???: There you are uncle! Finally!

All-Might spun around hearing the voice, turning to see a girl on some futuristic pogo stick jumping towards them.

She jumped from her contraption into a hug with All-Might.

Melissa: Welcome Uncle-Might!

All-Might let out a hardy chuckle.

All-Might: It's so good to see you Melissa!

Melissa: Oh my gosh it's been forever!!! I can't believe you're actually here!

All-Might: I'm truly grateful for the invitation! I almost didn't recognize you, when did you go and get so grown up?

Melissa: Well I am 19 now! Much heavier than the last time you've seen me!

All-Might: Are you? No!

He says, holding her up with two hands like she was a kid. And thanks to his massive build, he could easily hold up the tall girl like one. Off to the side, the three students just kinda watched in confusion. All-Might put her down.

All-Might: So, where's Dave hiding?

Melissa: Oh, up in his lab working on his latest project, you know him.

All-Might: Haha! That does sound like the Dave I remember!

Melissa: Glad to see your looking well, especially after that crazy fight!

Her eyes drift over to the students.

Melissa: Speaking of that crazy fight. You're Simon Tennyson! Am I right?

Simon: Yeah, that's me! And this is Midoriya and Tsu.

He says, pointing to the respective classmates.

Midoriya: H-Hello!

Tsu: Hey, ribbit!

Melissa: My name's Melissa Shield! A pleasure meeting all of you!

She offers a handshake that Simon accepted.

Melissa: So you three are in the hero course, right?

Midoriya: Yeah!

Tsu: Still technically first years though.

Melissa. That's still so cool! So, what type of quirks do you have?

Tsu: I'm a frog.

Midoriya: P-Power type! Lot of k-kicks and punches.

Simon: And I can transform!

Melissa: Wow!

She went over to Tsu.

Melissa: Your costume looks perfect for water! I assume latex?

Tsu: Yup, ribbit.

She then walks over to Midoriya.

Melissa: Hmm... yours is kinda basic design wise... but hey, simple never hurt! But I can't help but notice your lack of support items though...

Lastly, she walks over to Simon.

Melissa: And well, you're hardly even wearing a costume!

Simon: Eh, I'm gonna transform anyway, so might as well be comfy!

Melissa: Hmm...

She took his hand and carefully analyzed the Omnitrix.

Melissa: Hmm... impressive tech!

She looks up at him.

Melissa: Almost like it's alien or something!

She says in a confident tone, making Simon nervous.

All-Might: Ehem. Melissa, shall we?

Melissa: Oh! Yeah, sorry. I got distracted!

She grabbed her pogo stick, it folding up and fit in her pocket effortlessly.

Melissa: If we hurry, we can surprise papa in his lab! This way Uncle-Might!

She says excitedly.

All-Might: Follow me young ones!

He says as the group follow. They made it up to a lab where Melissa's dad worked. Melissa went in first. Simon could hear two voices talking from inside before Melissa went in.

Melissa: Well, you know me. I am my father's daughter! For better, and for worse!

Male voice 1: Melissa? Hey!

Male Voice 2: Oh, Mrs. It's nice to see you!

Melissa: Right back atcha Sam! Thanks for always taking care of papa, since he does nothing but work here constantly.

Make Voice 1: Oh, come on. I'm not that bad! To what do we owe the pleasure?

Melissa: Oh, you'll see! Since you completed the first stage of your research, I invited someone here to celebrate with us!

Male Voice 1: And who would that be?

All-Might took his chance to dramatically open the door.

All-Might: Yes! I AM HERE!!! SHAKING WITH EMOTION FOR OUR HEARTFELT REUNION!!!

He did a pose, silence filling the room while the three college students just watch from the doorway. Simon looks in, seeing Melissa's father with a look of disbelief on his face, with another man- presumably Sam- behind him.

Dave:... Toshi-... A-All-Might? Is it really you?

All-Might laughs before pulling his friend into a hug.

All-Might: I came all this way just to see you Dave old buddy!!!

He put him down.

Melissa: Well Papa, are you totally surprised!?

Dave: U-Ihh, yeah! Completely astounded!

All-Might: We both have Melissa to thank for that! Man, how long has it been?

Dave: Oh, come on! Don't make me say it, I feel old enough already ya jerk!

They share another laugh.

All-Might: I'm glad to see you again, my friend.

Dave: Agreed. I missed you too.

They share a fist bump. Then, All-Might steps to the side and turns to his students.

All-Might: Midoriya, Tennyson, Asui. Let me introduce you three to someone very special! David Shield-

Midoriya: I know him! Professor David Shield!

Simon: and there he goes.

Midoriya: A top scientist in the research world who received a noble quirk prize! He was All-Might's partner when he lived in Atlas! And he's a genius when it comes to costumes! He made All-Might's Young Age, Bronze Age, the Silver Age, and of course his Golden Age! He's the inventor of all those iconic looks!!!

He ran up to him.

Midoriya: I never thought I'd get to meet him in real life! I-I'm just so moved!!!

He says, shaking with excitement while Simon, Tsu and Melissa watch with amusement.

Dave: Hehe, well it seems I don't need to introduce myself!

Midoriya, realizing he went full fanboy, turned red from embarrassment and bowing.

Midoriya: S-Sorry!

Dave: No, don't apologize! I'm flattered, honestly!

Simon couldn't help but notice All-Might lightly cough, along with Dave seeming to notice as well.

Dave: Look, it's been a long time. Could the four of you give me and All-Might some time to catch up?

Midoriya: Yes! O-Of course!

Dave: Melissa, would you mind showing them around the expo?

Melissa: Sure thing! Sounds like fun! I'd love to show off all our work to upcoming heroes! Come this way!

Midoriya: T-Thank you!

Simon: Sounds fun!

Tsu: Nice meeting you Mr. Shield, ribbit!

Simon: ditto!

They leave the room, but Simon couldn't help but feel a little suspicious.

Later—

Melissa: So! What do you want me to call you guys?

Simon: Just Simon is fine!

Tsu: You can just call me Tsu.

Midoriya: Well... Why don't you call me Deku!

Melissa: Deku? That's kind of a strange nickname. You guys can stick with Melissa for me!

Later—

Midoriya: Whoa!!! This place was amazing!!!

They were now walking through the main Expo.

Simon: This place is pretty cool!

Tsu: Hard to believe the entire island is man made!

Melissa: And it has regular city stuff, everything you could possibly need! The big downside here is we can't travel.

Simon: Hm? Why not?

Melissa: The scientists and their families have to keep their research top secret. That insures there aren't any leaks.

Simon: Hm. Seems kinda extra...

Melissa: Maybe...

She quickly changed the subject

Melissa: You guys might notice all the heroes around! They're invited to sign autographs and help get more people interested in the Expo! They normally get new gear as well!

Simon: Free stuff? Sounds awesome!

Midoriya: This place is incredible!

Melissa: Lots of the pros will be at the big party tonight! But I'm sure you guys knew that since you came with Uncle-Might.

Tsu: Oh, I guess that's why All-Might wanted us to bring formal clothes.

Melissa: Oh, look over here!

She says, excitedly pointing at a building.

Melissa: You guys definitely have to check this place out!

Later—

Now inside, Melissa got right to talking about the cool tech. Planes that could go under water, diving suits, advanced helmets, anything you could think of.

Melissa: But now that I've shown you all of our tech... is it okay if I ask you about that?

She asks, pointing at the Omnitrix.

Simon: Ehe, that's expected.

Melissa: Sorry! I'm just curious!

Simon sighs.

Simon: It just helps modify my DNA. I added some security measures if I get close to death, and an AI that can advance my dna further in a pinch, nothing special.

Melissa: That's not a small feat! You could cure cancer with that kind of tech!

Simon: oh... yeah, it could...

Only now did he realize he didn't think of the ramifications when it came to his excuse.

Simon: I... might let you take a look at it some time-

Melissa pulls him into a hug.

Melissa: Oh, thank you thank you THANK YOU!!!

Ochaco: Looks like you're having fun Simon.

Simon looks over to see a very pale Ochaco looking at him.

Simon: Oh. Hi Ochaco! What are you doing here?

Ochaco: Looks like you're having fun.

She says in a shaky voice.

Momo: Ehem.

Simon looks over to see Momo, Jiro, Mina, Ryuko, Ruby, Weiss, Blake, Yang, Kendo, Shiozaki, Yanagi, Komori and Mei all standing there.

Momo: You apear to be having a good time.

Jiro: I heard everything.

She says, brandishing her earphone jacks.

Mina: Get your tits away from his face you harlot!

Ryuko: *Deep animalistic growling*

Ruby: Hello!!!

Weiss: Having fun? I hope not.

Blake:...

Yang: You two look pretty comfy...

Kendo: What a surprise...

Shiozaki: how sinful.

Yanagi: You little brat...

Komori: You still haven't shown me Fun-Guy!

Mei: So you let her tinker with your baby but not me? Is that how it's gonna be!?!?!?

Simon: I... feel like I'm doing something I shouldn't be...?

Finally, in walked Midnight.

Midnight: Well. Looks like you're having fun.

She says in a stern tone.

Simon:...

He looks back at Tsu.

Simon: Tsu! Help!!!

Tsu: They're mad at you, ribbit.

Simon: But why!?!?!?

He says, still between Melissa's breasts.

Tsu:... You cannot be this dense.

Melissa: Are these your friends?

Simon: Classmates and teacher. But yeah, friends!

Mina: Don't pretend you didn't hear me! Stop holding him like that!!!

She says, pointing at Melissa.

Melissa: Oh, umm. Okay?

She let go.

Mina: And you!

She points at Simon.

Mina: Quit being such a chick magnet!

Simon:... huh?

Tsu: What are you guys even doing here?

Midnight: I got to take a few of my own students with me and chose these lovely ladies!

Momo: My family got invited out and I was allowed some guests.

Weiss: So was I. Our combined guest count rounded out to this.

Blake: We drew lots.

Flashback—

Nora: WWWWAAAAAAHHHHHHHHHH!!!!!!

The girl collapsed to the floor due to failure to win the lots.

Flashforward—

Blake: Ended how you'd expect.

Midoriya: Well, it's nice to see some familiar faces!

Simon: Agreed!

Ryuko: So. Do we want him skinned, diced, or deboned?

She asks, pointing at Simon.

Simon: None please!
