I bet the people of Japan especially the children would love Waybig since he bears a huge resemblance to Ultraman. Plus I got an idea on Waybig's introduction, how about the scene on the episode "Ken 10" where Ken and Devlin were both fighting Kevin 11,000 and Ben 10,000 witnessing his son getting hurt completely pummels Kevin with Waybig, but this time its either the students or his team getting real hurt by All for One that he transforms into Waybig and does the famous "HOW DARE YOU!" scene from the episode. Waybigs punches could cause earthquakes while punching AFO, his cosmic ray can clearly hurt Gigantomachia since its powerful enough to overpower the Incursean ray which is a planet busting laser beam.

I just finished to read your storie, I like it is was cool most of parts, and i really hope you update it in the near future

Please write the next chapter! I'm really enjoying this

In the future chapters when the alien force finally encounter Gigantomachia I suggest have them use a Null Void projector on him to avoid massive casualties plus the league of villains would lose one of their most powerful Nighteye meeting Professor Paradox would be awesome, Paradox telling Nighteye to not always trust what he sees in his forsight quirk since the future always changes. Plus the the other heroes would be shocked that Paradox is a thousands of years old much older than All for One and is pretty much a god due to his time/dimensional travel abilities. Also Paradox is a time travelling superhero and has saved the world hundreds of times.

I'm just waiting for Ben and the gang to be paired up against top U.A students in a competitive match we all want to see them in action.

I like this story so far but I would suggest not bouncing around as much as you are doing. There are many scenes in this story that you are viewing as flashbacks when they could just be regular scenes. Not only that but flashback tend to break the flow of the story so it is best to only use them when it is important, For example, a character sharing something that happened to them in the past.
Good luck and I hope you can continue this story

absolutely brilliant! can't wait for the next chapter. keep it up.

Short, but interesting. pls continuo

One thing that I'm gonna talk about is the shipping... Who in their right mind chose Inko? You do realize that you chose Ben to be a teen instead of an adult right?
So why would it be Inko herself being chosen? It's like a certain someone has never watched MHA at all before doing this fanfic.

Another issue is that... What's the point of bringing the Alien team in this late especially during the Sports Festival period? They won't get to teach anyone until interning is over.
What is with the "Heroes" acting like a know it all? I hope that you realize that what Ben and his team does is totally different from what the Heroes from MHA does.

Plus Ben's responsibility is much bigger then All Might's responsibility as a Hero.
Ben has to protect the universe where as All Might can only protect countries or the planet if he could or could not since he already gave his powers to Izuku.

Don't get the Heroes dissing the Alien Team at all. Especially Aizawa. He's view on hero work is very bias.
And Ben doesn't answer to anyone other then the plumbers probably and Azmuth.
They have no rights to demand answers from Ben... Considering that if they knew that aliens were already living on earth and that those outside the planet have world destroying weapons... They would be living in fear every-day.
Especially since the Omnitrix can be considered as a weapon even though it's not suppose to be one.

To Hoppy854
That's highly unlikely of Ben to reveal secrets about the Omnitrix he'll probably just say that the Omnitrix is a device for understanding other species. Plus Azmuth already knows that Ben is worthy of the Omnitrix thats why he gave Ben the official Omnitrix in the first place. Also Azmuth once said that Ben is the only person that is worthy of the Omnitrix and the only person he trust to wear it. Ben is smarter than you think despite being a non chalant person he is always paying attention to his surroundings and pretty resourceful whenever he is in trouble, I mean he scored a 95/100 on the Plumbers Academy which shows that he is pretty clever and that he is just not using his full potential most of the time. He also has a photographic memory when he immedietely remembered the magic runes of Ledggerdomain just by glancing it for a few seconds. He is good at parkour and freestyle combat which makes him unpredictable with his movements, alot of people underestimate him but that is just what Ben wants he wants his enemies to underestimate him so that he could think of a plan while the enemy is either busy gloating or monologing. He pretends to be carefree and sometimes idiotic but in truth he is a smart, cunning and calculating person with a good heart.

Awesome chapter as always and I can't wait for the next one.

About Aizawa wanting Ben to disclose information about all alien threats to the public you should have Ben explain how majority of the species that are a threat to earth have weapons that can blow the planet up and if the public learns about it they would be living in fear. That is why the most powerful threats are a secret. And isn't it shown in Ultimate Alien that most of Earth's governments are aware of the Plumbers and support them secretly. Ben should just tell Aizawa that he(Aizawa) doesn't have a high enough clearance to know these things and the government heads have been made aware of everything.

it's not Lida it's iida

I remember where the base was. one of them is under Max's plumber shop. the other is Mt. Rushmore which is constantly blown up by Ben

It’s going to be a long time before Alien Force tutors anyone though. Right after the school sports festival the class gets sent out as interns. What’s the point of bringing them in so early? Anyway, about Aizawa’s contention with Ben, I really hope Ben points out that the decision of the alien watch’s secrets being revealed goes to its creator. If Ben revealed the watch’s secrets, Azmuth would not ever trust him with the watch. :)
