Now that My Hero Academia is finally finished, it's hard not to want more. Creator Horikoshi completely changed superhero world-building with his world where most people have powers and 'quirks', but only a few do not. With such an interesting concept, there's a lot of potential for hearing more from Midoriya's story even after it ends.

My Hero Academia: The fate and ending of all main characters
Wondering what happens to Deku and everyone else when MHA ends? This is where it all ends.
There are a number of directions a spinoff could go in: spending more time with already beloved characters, filling out hinted backstories, exploring more of the ideas presented, or simply continuing aspects of the story we have. There are many. take Which one you want to see will depend on what you liked about the initial story, but there are a few possibilities here.
10
Eri
A sequel about another future hero
Eri may not want to be a hero, but once she grows up, she's closest to Midoriya, who has a legacy character. It would be interesting to see her begin her work in his name after he saves and inspires her. The same way All-Might did it for him.
We'll also see the impact Midoriya has had on the next generation of heroes, and we'll see more about Koda, another child he saved. This could be the character's most interesting future spinoff right now.

AFO
Darker sequel series to My Hero Academia
With the timeline for AFO's rise a little unclear, it would be interesting to see a spinoff that witnesses his rise to power firsthand. Of course, it will have a darker tone than My Hero Academia and may give OFA's trail a little more screen time.
This spinoff could also double as an exploration of the chaos that occurred when Quirks first appeared and the political drama that followed. We might get some answers as to what exactly the strange phenomenon is and how it became so dominant in the world of My Hero Academia.

The Quirk Underground
The strange world of crime outside of villainy.
With the role of “rogues” occupying a unique position in dealing with the vagaries of the legal system, what has happened to none other than organized crime? Overhaul's arc briefly covers the world of organized crime, introducing the Yakuza who largely lost their way after the introduction of the Singularity.

Meet anime protagonists with some of the most unique abilities, from healing inner wounds just by breathing to manipulating gravity, space, and time.
It will be interesting to see the clash between the old criminal empire and this new breed of villain. This is especially true if the two of you become more intertwined over time.
7
Aizawa
Noir-style pro hero spin-off
Given Aizawa's appearance in the Vigilantes spinoff, his underground-style pro hero work could make for an interesting series. Not only will fans get to see more of the beloved characters, but the series will have a more grounded tone that better suits Aizawa's vibe as he attempts to bridge the gap between villains and heroes.
Furthermore, despite how close the two are, we never see Aizawa and Present Mike's fighting styles together. With fan favorite Shinso also as a mentee, there's a lot of potential for the team dynamic to become interesting.
6
Ochako
Carrying the torch for future heroes
A charming student hero, Ochako has enough personality to warrant the spotlight in a spinoff series about the quirky consulting work she does. We'll also get to see more of the characters we know and love.
Essentially, she will be taking on the role of the protagonist to continue the story we are familiar with. She's the perfect voice for a time of peace, and outside of a crisis, it would be nice to spend time with these characters.
5
quirky politics
Think of the members of the Meta Liberation Army.
There's a lot of politics going on behind the scenes that determines who's the hero, who's the villain, and how quirky expressions can be used in public. This is mainly seen in the main series, where it is revealed that the roles of the Meta Liberation Army include politicians, journalists, and corporate representatives.

Now that their story has been told, it will be interesting to see what others like about it too. Who is trying to pull the strings behind the whimsical regulations? How has the world been defined by these actors, for better or worse, and who will work to change what has been established going forward?

Lucas
Exploring what it means to be a hero
As the plot progresses, Kamui Woods learns that he has become much more popular since a fascinating documentary detailing his dark past was released in space. This sounds incredibly promising, and it would be cool to learn more about the character based on teasing his exciting backstory.
Plus, he and the other two members of the Lurkers, Mt Lady and Edgeshot, have a fun chemistry that could make for an interesting group dynamic in a spinoff. This may introduce even more professional heroes who take a different perspective than the students have.

spinner
Lee Hyung’s voice was left behind
As one of the last surviving members of the League of Villains that the heroes failed to save, Spinner becomes more interesting and emotionally complex. He was already the narrator of My Hero Academia's most unique stories, so he could take on that role again.
Revisiting fan favorites not only gave us more of his experience with League of Villains, but also allowed us to see how their legacies live on in the world even after their deaths. We can also take a much more personal look at the world of heteromorphic/homomorphic relationships. Maybe we can see what impact his book had on those few.

international weird story
See how the Quirk revolution took place in a new location
My Hero Academia takes place in Japan because it is a manga written in Japan by a Japanese man. So we get a good idea of how the strange phenomenon developed in Japan and what impact it had around the world. However, the series occasionally makes its way overseas, especially through movies.

Whether looking at an international collaboration of global pros or simply a story set in this universe but in a different location, spinoffs can be an interesting comparison to the original setting.
1
All Might
A full story about the man who inspired everything
It's a shame that we'll never get to see All Might in his prime, but a spinoff series could remedy that. As an incredibly powerful character who has inspired almost every student in the series, it will be pretty cool to see what all the hype is about.
There are also a few questions this series could answer, such as how All Might and Nana first met and what their training was like, how All Might and Naomasa Tsukauchi became so close, and what Lord Nighteye was like as an assistant. What better prequel to honor Midoriya?
