(Vincent is seen with his new team eating some ice cream.)

Ankh: Time to rest and eat ice cream.

Vincent: Eating ice cream is alright, but we can't rest yet.

Skylar: Especially when Hawkmoth and Lila have new allies.

Asuna: Who are none other than Tsubasa's former friends.

Tsubasa: I wonder who else is backing Hawkmoth up.

????: Maybe we can answer your question.

(Then they turn to see a green haired boy, a boy with half white and half black hair, a four arms man, two humagears, three girls, a boy with glasses, a man with a scarf, a humanoid bear, two kids, and many other young figures, besides some adults.)

Kagami: Who are you?

????: My name is Nezu. I'm the headmaster of U.A. University. The adults are, Eraserhead, Ms. Joke, Midnight, Present Mic and the Wild Wild Pussycats.

????: I am known as Recovery Girl despite my age.

Nezu: The youg ones are the Big Three: Tamaki Amajiki, Nejire Hado and Mirio Togata, there's also Hitoshi Shinso, Class 1-B, Izuku Hiden, Banjou Fuwa, Ochako Uraraka, Momo Yaoyorozu, Tsuyu Asui, Fumikage Tokoyami, Tenya Iida, Mezo Shoji, Yuga Aoyama and Koji Koda.

Eraserhead: The two kids are Eri Hiden and Kota Izumi.

Ms. Joke: And the two female figures are the humagears Izu and Azu.

Vincent: My name is Vincent. These are Tsubasa, Skylar, Asuna, Kagami, Zoe, Nino, Luka, Ayla, Daigo, Kasumi, Hajime and Ankh.

Izuku: It's a pleasure to meet you.

Tsubasa: So? You said you know who are Hawkmoth's new allies.

Midnight: And we know. They're the League of Villains and some of the former students of U.A.!

Hajime: You must have had a justifiable reason to do so.

Mic: And we did.

(A Flashback shows Izuku being accused of betraying U.A.)

Eraserhead: Our problem kid, who used to be a Midoriya was unfairly accused of betraying us. And nobody believed in his innocence, except for us.

(All Might is seen taking the One for All from Izuku, and giving it to Bakugo.)

Kota: The one who was once considered the number one hero, simply took the One for All from him and gave it to Katsuki Bakugo, who was the one who accused Izuku.

(Ojiro, Mina, Kyoka, Denki, Mineta, Eijiro and other few 1-A Class are seen beating Izuku near death until two Quirks are awakened within him.)

Izuku: When I was about to die due to the beatings I was receiving, I awakened two Quirks I didn't think I had.

(Banjou Fuwa, who was Shoto Todoroki is seen showing the evidences of the true traitor.)

Banjou: I used to be called as Shoto Todoroki when I gathered some evidences of Izuku's innocence, and showed them that Katsuki Bakugo was the real traitor. He joined the League of Villains to get rid of him.

(Then Izuku, Ochako, Momo and Banjou, who was still Shoto Todoroki, decided to leave U.A.)

Ochako: Then we left U.A., without looking back.

(Izuku and Shoto are seen in split screens, saying their last words for their families.)

Izuku: Mom, I'm sorry.

Shoto: Fuyumi-nee, Natsuo-nii, tell our parents that I'm sorry!

(Then Shoto is seen faking his death.)

Banjou: Then I faked my death so the ones who planned to take revenge on me wouldn't chase me.

Shoji: Just like your brother Touya before he became Dabi.

(Flashback ends)

Momo: And today we're here.

Tsubasa: It looks like I'm not the only one who was betrayed by the ones I considered as friends while I was Marinette Dupain-Cheng.

Izuku: Well Marinette, we all have one thing in common: we've all been betrayed by the people we trusted the most!

(Suddenly a citizen is seen running away, scared.)

Monoma: What is he running away from?

Koji: (points at something) Uh... guys?

(Then the heroes see two male figures flying while having lightning in their hands as they approach a fallen female hero.)

????: Poor Spider-Man.

????: I just wanted to see his face when he finds out what we did to his friend.

Vincent: These two are going to kill Spider-Gwen.

Skylar: We gotta act!

(Then Vincent, Skylar, Asuna, Kagami, Zoe, Tsubasa, Daigo, Kasumi, Hajime, Izuku, Banjou, Ochako and Momo prepare to transform.)

Build: Are you alright, Spider-Gwen?

Spider-Gwen: Ugh... thank you.

Ark-Zero-One: (to the villains) Who are you?

????: I am Electro, and this is my sidekick, Electro Junior.

Zero-One: There's only one who can stop you, and that's me!

Thouser: He looks familiar to me.

Jin: So you joined Hawkmoth, didn't you?

Electro Jr: You will tell us what you did to Gabriel's son, or else you will DIE!

Horobi: Really? I guess you and Adrien deserve each other.

Ikazuchi: I'm calling down the thunder!

Naki: Naki is here!

Electro Jr: Enough! We're going to fight you!

Valkyrie: Violations of the LOV spotted. Destroying targets.

(Electro charges at Kamen Rider Build, who punches him away.)

Electro Jr: Damn you!

(Then Kamen Rider Ark-Zero-One kicks Electro Jr.)

Electro Jr: How did you...

Ark-Zero-One: You don't need to know anything.

Horobi: Hawkmoth made a big mistake trying to stop us.

Jin: He is screwed!

(But then Electro returns trying to shock Kamen Rider OOO, who simply multiplies himself)

Electro: What?

OOO: I'm like an one-man army.

Naki: We could hand you over the authorities, but you would escape over and over again.

Electro: So you know that we'll never stop until we get what's rightfully ours.

Vulcan: Well, I guess nobody will miss you, villain.

Electro Jr: That voice... (angry) You...

(Electro Junior angrily charges at Kamen Rider Vulcan and punches him various times, but Banjou seems unfazed.)

Electro Jr: THIS IS YOUR FAULT, TODOROKI!

(Then Kamen Rider Vulcan grabs Electro Junior in the neck.)

Vulcan: Shoto Todoroki is dead! I'm Banjou Fuwa, Kamen Rider Vulcan!

(Then Kamen Rider Vulcan punches Electro Junior away, surprising Electro.)

Electro: You guys give Spider-Man and his friends a run for their money.

Build: Because we don't slack off our training. Unlike those fake heroes, who joined the League of Villains and Hawkmoth.

Ark-Zero-One: That's right. Now prepare to be finished!

B. Driver: Vortex Finish!

(Build uses the BLD Prism Glove to create a gust full of diamonds and uses the Muscle Glove to punch them at the enemy. The diamonds creates a tornado which envelops Electro and Electro Junior.)
