(A/n: Forgot to mention Female Shinsou shall take Mineta's spot)

3rd POV

Class 1A along with the big three who came on this trip had their backs against the wall. Their teacher Aizawa was beaten to a pulp and Pro hero thirteen down as well and no help on the way or so they thought.

Miria: "Ok guys we need to protect the 1st years no matter what" She told her 3rd year peers

Nejire & Tamaki: "Right" They said getting ready to fight more Villians

Shigaraki: *Laughs* "It's useless useless useless! Nomu kill them!" She said as the monster goes for an attack but was stopped by a boy with brown hair and green eyes shocking everyone

Boy: "Looks like I just got here in the nick of time" He said with a smiles as he sips a smoothie and finished it "Ok ladies sit back and let me handle" He smiles pulling up his selves showing a weird watch on his right arm causing some of the students to gasp

Boy: "It's hero time!" He said slamming his hand down on the watch as he transforms

(Feeling old yet?)

Boy: "HeatBlast!" He said as everyone was shock a boy with a quirk impossible they all thought besides the ones who knew him

Boy: "Time to heat things up!" He said blasting the villains took out a good majority

Shigaraki: *Starches neck* "My plans my plans have been side tracked because of this secret boss Nomu take him down but keep him alive" She told the monster as it the boy tried to burn in but it simply regenerated

Boy: "Power for power then" He said transforming again into a dinosaur like creature "Humongousar!!!" He said as him and the monster started trading blows for blows

The students were both shock and amazed

Denki: "No way he's keeping up with that thing"

Shouka(Female): "Impossible that thing was meant to kill all might *Is that really you Y/n?* "

Izuka: *in head* "No way Y/n it's actually you"" She thought trying not to cry

Momo: *In head* "Y/n you came back and you're saving me and my class" She thought smiling

Nejire: "Whoa Y/n is still so cool!" She excited

Miria: "He's grown so much" she smiles as tamaki nods

Y/n: "And you're outta here!!!" He said punching Noum out of USJ then turning to the league of Villians who made a hasty escape after Shigaraki was shot but snipe

Allmight: "Students we are here!" She said but seeing Y/n as Humongousar she thought he was a villian and charged at him as Y/n quickly transforms into rath catching her fist

Y/n: "LET ME TELL YOU SOMETHING ALLMIGHT THE RATH DOESN'T APPRECIATE BING ATTACKED AFTER SAVING YOUR STUDENTS!!!!" He said transforming back to normal

???: "Y/n!!!!!"

Y/n: "Uh oh"He said as he was kick in the face by the rabbit hero Miruko

Miruko: "You idiot I told you to wait for me!!" She said pulling his cheeks giving him an earful

Nezu: "Ah yes class 1A this is Y/n Tennyson he is the first ever male with a quirk as well as being the a current pro hero making him the youngest hero ever know as Ben 10 as Miruko is his adoptive sister as he was adopted into her family" she said as they all were shock as a there was already a boy who was a hero "Also due to Miruko feeling he needs to be among peers his age he's your new class mate" she said as they were all shock

Students and heros: "What?!?!"
