OK, I am 100% following this.

I do love me some Aizawa.

Well now, this is certainly going to be interesting. I'm very curious to see where this goes. And how Deku's going to handle certain things in the future. And yes, it was the right call to skip the initial freakout. It's not hard to imagine.

Just the ones outside the series I say.

Give us a list of who's in class 1-A

this is kinda bad

I'm impressed with the fact that you put in a great villain like V.V. Argost. Also, I think you could do all three.

Rofl Argost and Present Mic, Dr. All Might.

Oh and the omnitrix u I dream translator.

Ya know you could probably get away with adding in aliens and or creatures from other miscellaneous series and franchises since there are supposed to be over 10 million aliens in the omnitrix. Nice chapter, I look forward to the next update.

This is gonna be a bit of a critical review sadly, so fair warning.

Honestly I'm baffled and lost at what is going on. You don't clearly explain who is talking and when, such as the beginning of the chapter where you don't even mention All Might/Toshinori's name until the tail-end of his internal monologue on who would inherit his Quirk. Yes, some people might connect the dots before the end. And then I didn't get what Present Mic was complaining about or why. Like, was he upset that Izuku somehow simultaneously taught himself and his classmates different languages or something? Did he find the universal translator that unfair? It seemed petty.

Not to mention why would Present Mic know about All for One? I thought All Might kept that battle a very deep secret that only some police friends and Gran Torino knew about. That whole first scene felt confusing, even ignoring the random levity parts where Present Mic would provide fourth wall breaking commentary on new stuff (and that odd time with Professor Paradox in that REALLY oddly implemented bit of a Yamikumo). I get this is a different universe and stuff with blending in a bit of the Secret Saturdays but I think you're falling into the same trappings you have in your other story, the Pokemon Reset series.

You're introducing so many different lore stuff and not getting into what the main clutch that this story is about. This is supposed to be about Izuku with the Omnitrix, right? I don't see him as a main character at ALL here because the attention in this story, and this chapter especially, is all over the place. Yeah, Izuku gets some scenes like hanging out with friends, but the narrative jumps from one perspective to another, and you made the conscious choice to avoid the entire 10 months prior where the canon story starts. From there it introduces three main characters (Izuku, Bakugou, All Might) and explains how being a hero in that setting is everything. You starting the story at the entrance exam cuts things quickly but doesn't give us as much time to ease into things like understand or struggle with Izuku as he gets stronger. I get maybe writing a chapter of Izuku finding the watch and easing into it might be boring, but it would have given us context. It would have given us time to connect to Izuku.

And you fail to give Izuku time here, time he desperately needs to feel like the star of the story. My advice? Cut back from the lore of the world we don't know or care about and give more time on Izuku, even if it's by flashbacks. Like a flashback as he thinks back how fair he's come since finding the watch. Or thinking back to how Bakugou reacted to his watch powers as he watches him and Todoroki fight in this chapter. Or anything to give him more character; thinking of hero names for his aliens, his high of being an alien and then conflicting emotions when he's back to normal, SOMETHING.

I like Ben 10 and My Hero Academia (and kind of liked Generator Rex and Secret Saturdays when they came up too), but IMO this story feels like a really flawed execution so far. I hope you don't take this as a flame and more of a constructive criticism on how to make it better.

Nice

So far I really like this story but the fact it's not just a crossover between Ben ten and my hero academia, but it's crossing over with G.I. Joe, the secret Saturdays and generator Rex more to come will just a awesome story I can't wait to see what others shows will appear please continue

Neat it's Argost to paraphrase a bum from Chicago Oh my god he's one of the greatest cartoon villains I've ever seen in my life

no seriously Argost/the secret Saturdays were super awesome so much that I didn't even question it when they crossovered with Ben Ten something I realized after I did my Chester impression

So the Class B students in 1-A are Kendo Shiozaki and a third person who might have been named in Chapter 2

excellent work on this chapter and yeah present mic just gave dark ideas and the fight scene was awesome :D

Overall, a pretty good chapter. The battle training was nicely done, especially with how easily Midoriya won, and Shiozaki being in 1A is a nice surprise, since I was under the impression that Kendou was the only 1B student in the class now. The Secret Saturdays villain showing up was a nice touch, and that metatextual rant he went on was fun to read, and David being a descendant of Destro is a pretty cool change. The one thing I have to comment on is in the beginning of the chapter where All Might says that One for All boosts the Quirk of its user. One for All increasing the power of a wielder's Quirk wasn't a thing until Midoriya obtained it, so Nana shouldn't have had something like that happen to her. Other than that, good chapter.
