The students of U.A high are sitting at the GYM waiting for their teacher to arrive.

Deku and the others wonder whats taking Mount Lady so long, but then a man in white and red walks forward and starts speaking.

"Greeting, Mount Lady is a little tied up at the moment so I was called in to be your substitute teacher. You may call me Omni-Man."

"So today we are going to have a sparing match five of you vs me. Lets see, Bakugo, Deku, Shoto, Denki, and Tenya you five will face me. Everyone outside to the training area."

As they are getting up to head out Deku asks a question.

"Excuse me, Mr Omni-Man, whats your Quirk?"

"HEHE, that's the funny part I don't have one."

All the students freeze wondering "WHAT!? HE DOES NOT HAVE A QUIRK!?"

"Alright, get into your hero suits." Omni man says

Everyone heads outside with the other students watching from outside the arena.

While the five stand looking at Omni-Man confused.

"Ok, seriously what's your quirk?" Tenya asks

"Like I said I don't have one."

"Then how do you plan on teaching students who have quirks?"

"I am in pretty good shape for a 45 year old wouldn't you say?"

"Alright old man, I will finish this quickly by giving you a love tap!" Bakugo yells

"Old man?" Omni-Man asks as he walks forward slowly

Bakugo runs at him and jumps to punch him, he is about to but Omni-Man disappears with Bakugo's eyes widening.

Just then he grabs Bakugo from the back of his collar and throws him across the ground.

"What the!?" The students ask

"I thought you said you did'int have any quirks!?" Bakugo asks very mad

"Well, I am not from your planet is the thing. I am a Viltrumight, I am from a different planet."

"And with me being born on a different planet, I am born with natural ability's, not Quirks." Omni-Man says

"Now then lets fight!"

Omni-Man dashes back at Bakugo and they start brawling.

Bakugo punches him, but he punches back, Bakugo uses his quirk to blow him up, however Omni-Man gets back up and punches him in the gut knocking him out.

Denki then charges at him, shooting electricity at him.

Omni-Man screams at the pain but presses on and punches him.

Deku realises they need to team up in order to take him down.

The three dash at him and each use their quirks to try and take him down.

Shoto uses his ice and freeze him in place, but he breaks free and throws a mean punch.

Shoto uses his fire to slow him down while Deku goes in to punch him, however he grabs both by the neck, Tenya uses his Super Speed to try and gain the advantage, but he looks at him and Tenya realizes he clucked up.

He throws the two and uses his speed to attack him and knocked him out.

Deku is the last one standing, with the two having in intense battle.

Deku and Omni-Man block and attack each-other intensely.

But overall Omni-Man came out on top.

Very battle damaged.

He reaches his hand out to Deku and picks him up.

"You did good kid, all of you did."

They head over and get healed by the medic.

"Mr Omni-Man, I was curious you seem very powerful, why are you not a hero here?"

"Well Deku, I have my own city I protect outside of Japan, I just came over as a favor."

"But you got some talent kid, but my son is Invincible."

"Keep up the good work kid!" He says as he flys off

The next day the students are waiting for their GYM teacher again and Omni-Man walks in.

"Sorry students, It seems Mid-Nite is also a bit tied up right now."

Cut over to Omni-Man's apartment both Mid-Nite and Mount Lady are both hand cuffed and have a double ball gag on them, as they struggle to escape.

They also have collers on them, keeping them from using their quirks.

"See ya later ladies, I have somewhere to be." A misterious figure says

"Now then I would like to introduce you all to the new substitute teacher..."

"HOMELANDER!"
