It was amazing. please update soon.

I noticed that there are many similarities between this story and another one where MCU Peter Parker with the Venom come to the universe of My Hero Academia, is it intentional?
because some scenes are bit to bit identical while others are just very similar.

i love the story so far, its like the story would actually feel excluding the ship, also you've been hanging on big chill a lot

This is so good

I love how you stay true to Ben's character, by being a vigilanty and whanting to help people.

Good

this is a very interesting story

Keep going!

Ben X Melissa X Nejire

Hope you don't nerf Ben. By the end he even had full control of Alien X. If you do decide to put him in UA put him as a member of the faculty. His experience is greater than all the pro heroes of BnHA since he has fought against all types of enemies from aliens to sorcerers so it would be a little insulting if you put him with students with no experience. For pairing use someone older like Nejire or maybe Mt Lady or even Midnight.

Great story!
But for pairings, I think
Ben x Melissa
Ben x Nejire

Good chapter
Yes I got my pairing.
I kind of hope if they do capture Ben and Ben tells them everything if you going that way becaise I don't know that he becomes a teacher ad sinse 6 years of experience of being a hero making him a pro already either though Ben 16 years old and seeing how if I remember correctly UA only has four years of school making Ben going to school being pointless to me any way.

Here's the thing about vigilante's, They go both way's.

#1: In it for themselves.

#2: Self-sacrifice, not for glory and/or recognition, just, Because its the right thing to do!

Good written chapter although I have some things to go over

Dont underestimate or put ben under all might considering ben has a greater arsenal of aliens and multi tudes of aliens stronger than the mha universe or more laiens with abilities that can combat any quirk and ect.., also minor nitpick with the omnitrix glitch since this was corrected in later AF seasons and Ultimate Alien and should give him his alien he wants most of the time with some fault.

Also to be honest having ben in a school would hold him back since he already knows what the essence of a hero is and how to act and be like one and having more experience than the U.A body and comparable with most pro heroes and it kinda opens up more issues with our favourite chimera sui down the road.

Also since there isnt no ultimate function would there be a albedo in this universe?, as well it would be cool although it be complicated on how he gets implemented into this story.

Have ben paired with someone his age maybe(like melissa or nejire or someone in one of the previous comments) and have mina as a really good friend?.

One Last Thing
Maybe have ben face off against the mha villians in the future like it would be cool to see all for ones face combating ben and his multi tude of forms and how he cant steal or use his "quirk", and the league of villains and add a member that contrasts ben onto the team whom is like him as a vigilante or a pro hero starting out or someone whom is willing to be on bens side outside of gwen and ship?

My vote for pairing is:-
1. Ben x Melissa
Or
2. Ben x Nejire
And for the A.I of omnitrix I think it should be Eunice.
Keep writing !
U r writing a awesome story!
Hope u update soon!
