When Disney Makes A ‘Big Hero 6’ Sequel, They’ll Almost Certainly Bring Back Tadashi.

I’ve been hanging on to this theory since before I even watched the movie back in November. In fact, the movie itself almost confirms that this is what will happen when Disney ultimately makes the Big Hero 6 sequel.

Oh? You don’t think there will be a sequel?

Here we go.

Big Hero 6 is one of the riskiest animated movies Disney has ever made. Period. They’ve never spent that much money to make a film based on something so obscure. Even Wreck-It Ralph and Meet the Robinsons looked better on paper to a Disney executive.

And it paid off. On top of getting the Academy Award nomination for Best Animated Movie, Big Hero 6 made half a billion in the box office. Only Frozen and The Lion King have made more money than this film.

That, and it’s based off of a serial comic connected to Disney’s other money-making machine: Marvel. And if there’s one thing Marvel and Disney know how to do together, it’s making Marvel sequels.

Keep in mind that although Disney has traditionally shied away from making sequels to its flagship animated features, they’ve also learned from Pixar and even DreamWorks that sequels are worth doing if the creatives behind them want the story to be told.

That’s why even Wreck-It Ralph is getting a sequel, and Frozen is of course getting milked in all sorts of media. Even though it’s not in development yet, Big Hero 6 is almost 100% for sure getting a sequel. And it will probably be called…

Big Hero 7.

That “7” will belong to a character we know from the first movie: Tadashi. I’m calling it right now. He’ll be a villain of sorts in the sequel, inevitably joining the team fully to add that number (after all, Big Hero 6 2 is just weird branding).

But wait! Tadashi isn’t a superhero. He’s not even alive!

Only one of those statements is true, considering he was a hero, as proven by your belief he died.

Let’s put on our flashback hats and revisit just what exactly happened to the older brother of Hiro Hamada.

Hiro wanted to get accepted into the robotics program at the university where his brother and friends attended. To do this, he had to impress Callahan amidst a competitive group of other scientific geniuses. Somehow, a fire broke out, trapping Callahan. Tadashi, Hiro’s older brother, ran back inside to save him, but the building exploded moments later.

Later, we learn Callahan survived by accessing Hiro’s microbots, but it appeared Tadashi didn’t make it.

Look, if you know anything about movies, it’s that if there’s no body, that character is alive. That’s just a rule. I’m not the one who made it up.

Second, the inclusion of a fire is tantamount to how this theory works. Where do you think it came from? Most likely, one of the inventions, and no one else apparently died from its flames.

I believe this invention had to do with nuclear energy. Why? Because Big Hero 6 (and Disney) is purposefully setting up Tadashi to be Sunfire, one of the original members of the first Big Hero 6 team and a prominent character in the Marvel universe.

One of the inventions, or even something special about the fire itself, must have given Tadashi abilities that would protect him from harm, ultimately transforming him into Sunfire.

Now, I imagine a good number of you already assumed this because you know certain things. Well, here’s some more ammunition for you to spread around.

Sunfire is a Japanese mutant (like X-Men mutant) who can absorb heat and turn it into plasma. In the comics, his mutant powers were triggered by radiation from Hiroshima. He’s been in comics since the 1970s as an Uncanny Avenger, member of the X-Men, and of course, a member of the original Big Hero 6 team.

One important thing to note is that Marvel is currently forbidden from even using the word “mutant” in its movies, making it difficult for them to use any characters from the X-Men side of Marvel. But they have managed to find wiggle room with characters like Quicksilver and Scarlet Witch, who have many affiliations.

The same can easily go for Sunfire, and his story arc is already perfectly progressing. When Sunfire reluctantly joins Big Hero 6 in the comics (after being found by Hiro, no doubt), he actually gets possessed by their enemy and becomes a villain.

I doubt the movie would use this villain, who is known as Everwraith, because he’s literally the combined legion of souls destroyed by the atomic bombs that fell on Hiroshima and Nagasaki. That’s tough to write out. But Disney could easily find another way to leverage this story arc to create some compelling narrative surrounding Hiro and his lost brother.

After all, can you imagine a fight between Tadashi/Sunfire and Baymax/Hiro? That would make Revenge of the Sith look like The Babysitters Club.

And hey, if Elsa can have ice powers…

My biggest evidence for this theory being true is the fact is that this all fits way too perfectly for Disney not to do it. I can’t even imagine what else the writers should or could do to make the sequel even bigger than the first movie, which frankly suffered from being too much of an origin story instead of a movie about superheroes actually being superheroes.

Big Hero 6 is one of the most beautiful animated films of our time, and a beacon of the Disney Revival. And that’s why I think it deserves a sequel that delivers a story that is just as sincere and passionate as the first one.

And hopefully, more of the team outside of Hiro and Baymax…

  1. I heard Big Hero 7 WILL have Tadashi returning. I don’t know if this will be confirmed, but I read that Stan Lee said that it will happen.

    • Well I don’t know. We thought Elsa and Anna’s parents would come back… did they? Nope. We thought that there would be a Tangled 2… nope didn’t happen. Sorry to break it to you but… IT HAS BEEN A FRICKING 6 YEARS, Y’ALL!!! I don’t think there will be a second movie. Or Tadashi returning. Although ‘Big Hero 6’ was a great movie and all, there are some things that y’all do NOT understand. If Stan Lee wanted to make Big Hero 7, then he WOULD’VE already done it. Who agrees…?

      • he more likely in the process of doing so and died in the middle of creating the big hero 7. there could of been like the cliff hangers that are in different movies that did great in story telling but just no one bothered doing the tying up the loose ends cause they thought everyone would want to see them at the movie theaters. but really most of the time the movie theaters do cost a lot for some people already and that is not very good if people want to go and see a movie and need to choose meals or a movie with family at the theaters

    • I think Tadashi should come back burned and with fire ablities, hiding it from the team. The beginning would show what really happened when he went in the fire. The nuclear elements from one of the experiments would seep into the fire, Tadashi would get a burn on his cheek and the nuclear air would go inside, giving him extreme temperatures and high burning levels. He would accidently create a burst of fire, making the fire worse outside. Then we’d come back to the present, Hiro looking at Tadashi’s hat.

      • If there were going to be one.

  2. This theory is a little far-fetched,but I hope at least some of it is true,because I really want a sequal to Big Hero 6. It’s really just too awesome NOT to have one. Plus,Tadashi will come back! EVERYONE wants Tadashi back! It might just work.

  3. Omg, you just made me cry. Ok, it will sound very weird, but when I watched Big Hero 6 for the first time, i thought “hum… Tadashi reminds me of Newt, from Maze Runner” ok, spoilers: NEWT DIES IN THE THIRD FUCKING BOOK. So, when Tadashi dies, I cried my butt ofr, because, God damn it, just because he reminded me of my sweet Newt😂😂. Well, when I saw this, I felt really happy. When I read the part when Newt died, i spent all my day thinking about other ways he could be back. Of course, he really died, damn it😑😑 Well, now, at least, Tadashi will (maybe) be back❤️❤️😭😭

    • I always cry when Tadashi dies.

  4. There’s no way I’m not freaking out about this!!! I mean, WOW!!! I can’t wait!

  5. Whoa, Tadashi could come back? That is so freaking awesome! Can’t wait! 😉

  6. Its a good theory but youve forgotten one thing.. The movie rights to sunfire are currently owned by 20th century fox as he was featured in xmen days of future past. Tadashi returning as a villain is definately a good idea though

    • Well, after the Fantastic Fail and Fox’s desire to develop an X-Men TV show (something to which they do not currently have rights), Marvel might not just demand back the rights to Fantastic Four, but Sunfire as well. Get your popcorn ready, because those negotiations are going to be prime-time entertainment.

      • I’ve looked it up. There should be big hero six 2 on November 6 2020. Also, in the movie, bay max states that tadashi is still with them… think about it

        • Didn’t happen, sadly. I think that was just an idea on Fandom. No word of a sequel yet. 🙁

    • No, that was Sunspot in Days of Future Past, who has similar powers to Sunfire. Sunfire is a different person. You may be right about 20th Century Fox though.

  7. I just found something that might support this theory even more.
    On Tadashi’s hat, there is an “S” and an “F”. The letters stand for Sunfire, which, according to your theory, is who Tadashi will come back as in the sequel. It has been confirmed that the letters do stand for Sunfire, which MIGHT mean that Disney was planning this.
    Again, might. I’m really going out on a limb here, but I thought that was cool that the letters stand for the character in your theory. Please tell me what you think.

    • They could also stand for San Fransokio, but your theory is way cooler.

      • Yep, it’s San Fransokyo.

  8. I agree with you. It would be a great plot but I think they’ll make him a new hero

  9. I don’t really know about the Sunfire thing, but if Tadashi comes back I’m all for it! 🙂

  10. It would be a really interesting sequel if the baymax in the time vortex came back as an evil baymax because he still has the fighter chip inside him. I REALLY HOPE TADASHI IS ALIVE AND THAT THERE IS AN EVIL BAYMAX!!!😱😱😱

    • To be honest, I don’t think there would be an evil baymax. He is the main character in the movie, “Big Hero 6.” What I do think just from pure imagination that a team member from big hero six will betray he/her friends.

      • actually, in a game called Kingdom Hearts 3, they are having this place as a world and Supposedly the baymax left in the Vortex is going to appear as a evil baymax.

  11. I don’t think it will be Sunfire. Yes, Marvel found some room for Quicksilver and Scarlet Witch but if i remember correctly they were the only two Marvel characters that were specifically stated to be shared by Fox and Marvel. And honestly, Quicksilver and Scarlet Witch have more business in an Avengers movie than an X-Men movie. While they have historically been known to be mutants (recent comics actually changed that…. they are no longer mutants and they are no longer Magneto’s children; apparently it was a lie all along), they are primarily Avengers and are more commonly associated with the Avengers than the X-Men. Given that, the likelihood of Fox also allowing Marvel to use Sunfire in their movies is incredibly low since Sunfire only recently joined the Avengers (within the past 5 years or so) and is much more commonly associated with the X-Men. So I highly doubt Marvel would be able to get their hands on Sunfire. Also, going by the logic that Sunfire is both an Avenger and an X-Man, that’d mean that Marvel would also have potential access to using Wolverine, Storm, Rogue, Beast, Havok, Cannonball, Firestar, Sunspot, X-23, and Namor in their movies too (I think there may even be more characters who have been on both the Avengers and the X-Men). I don’t think Fox would let a single one of them go over to Marvel easily.

  12. i just hope for the movie to come out and i definitely cant wait for tadashi to come back

  13. tadashi survived but the explosion gave him fire powers
    (Just My Imagination)
    Imagine it

  14. Stan lee OWNS marvel he can do whatever the hell he wants.

  15. sunfire that will be really weird because… of course maybe tadashi will get fire powers but it’s just fire why the sun? will if they really mean it that tadashi will return and he will be a super villain and tadashi will have fire powers i will bring some popcorn and his fire will pop them up! CAN’T WAIT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  16. i heard big hero 6 sequel will come in 2019. okay i better get my popcorn ready i can’t wait to see tadashi and everyone hiro and fred and gogo and honey lemon!!!!!!!!!!!!!!!!!!!!!!!! i can’t wait till 2019!!!!!!!!!!!!!!!!!!!!!!!!!!!

  17. I think we all know what’s comming now that disney bought FOX 😀

  18. Don’t know if anyone wants to know what the hat actually stands for it stands for the school’s name SFIT san fransokyo institute of technology

  19. I think that WOULD work, but now there’s a series on Big Hero 6 and so I’m not so sure anymore.
