Steven Gets CORRUPTED?! How and Why! Steven Universe Future FINAL Villain Theory!
The Roundtable
A popular theory going around for Steven Universe Future is the concept that the giant beast looming in the background of the villains crowd shot is none other than Steven himself, corrupted. How and why could this happen? How would this impact the Crystal Gems, the humans of Beach City and the Diamonds? Let's break down the original theory and spin it into how it could work organically into the story!

    Do you guys think Steven could get corrupted into the giant beast in the theme song? We have another theory on who this creature could be, but it was really fun throwing our two cents into this one! ORIGINAL THEORY: THUMBNAIL ART BY JANKYBONES:

      Here's a theory maybe ccorrupted Steven is controlling white like he did with the Lars, and the watermelons Stevens. then using white power combined with his i controlling multiple gems at once

      Impossible, he’s the main character, the number one rule of a tv show is that the main character of a show doesn’t have anything bad enough that happens to them that it changes the character entirely (aka a main character can’t be completely changed in every single way)

    • Kire Gore

      yes I think that it is steven corrupted. Maybe he was forced to fuse with a corrupted gem? Just maybe...

    I think Steven tried to heal someone that's REALLY hurt them he got corrupted because he was stressing out

    If you see the cactus type of thing with multiple heads, doesn't it look like a type of Steven plant like the watermelon Steven except something bad happened to make it evil?

    With the “Steven has a physical body” thing, It could be like his body being sort of... trapped in the bigger hologram with mass that is gem forms. Like being trapped in jelly or ice or something. Or piloting a giant robot

    one thing that could save him The Rose Quartz Healing Fountain with the diamonds

    Am i the only one that thinks that Its Pink Steven got out of Steven’s body and reformed as a corrupted gem, this makes Steven a normal human without powers.

  • Jawbreaker The Hyaenodon

    Maybe his corrupted form will look similar to Jasper’s except his is pink and has a long neck. Like a giraffe.

  • Hoih2

    That would mean steven would still have horns or something like jasper

  • břiãńńã_ťĕrrøñěś

    is it bad that I kind of want steven to be wormy boi💀

  • voomee or woomy

    I was thinking that Steven would be PHYSICALLY corrupted, but not MENTALLY because of all of his changing.

    I don’t think it will be Steven because the worm is so big! If you saw Jaspers corruption she was almost the same size as she was before as original Jasper before her corruption.

  • Angel Guevara

    Steven can't get corrupted because no one else is corrupted that he can fuse with and why would the diamonds corrupt Steven.

  • Arista Dyan

    I reallllly hope this doesn't become a thing because of how heartbreaking it would be, but if it does I just hope he can be saved.


    nah, i think this is the gem that comes out of the earth after all of the injector juice from the movie

  • ItsUnicornPlayz

    Okay let me explain some more. Okay Steven is corrupted. They need all the diamonds to save him. But wait! Steven is a diamond!!! Okay let’s rewind to Steven running. Wait is that a black shirt I see? So if your not on the same page as me what im saying is in Steven Universe original series Steven had a red and yellow shirt. In Steven Universe the movie Steven has a blue shirt with a yellow star and a pink (I forget). So in the original Steven universe Steven has a yellow star on his shirt. Maybe that meant yellow diamond...? Then in Steven Universe the movie he has (already told ya) so the blue might mean blue diamond and pink might mean pink diamond. Okay now onto Steven universe future. He has a black shirt. Black diamond? Will the black diamond save Steven? Okay onto another theory. Okay so Steven helped centipeedle. Maybe this is the time centi will help Steven. Not much stuff to backup this idea :/ What do you think?

  • Dr Wrecker
    Dr Wrecker

    My theory is that Steven trained himself to live without his gem over the 2 year time skip

  • Shadow

    I really hope Steven gets corrupt and if he does then I *NEED* to see the centipedle help Steven just like Steven helped Centipedle

    what i think is after fixing the earth (smooching it like a million times) he picked up poison on his lips and when he gets emotional he goes corrupted until something calms him, i say this because he could partially heal corrupted gems, so why not heal himself in which he cant do it for very long thats where the emotional part i added comes in, seeing corruption is seen as a tear in the mind his mind could become sensitive to emotion, so yeah thats my theory.

    One of the episodes said that corruption was caused by white diamonds light radiation

    Even gets corrupted by either chipping his gem or it is have to deal with that pink version of white diamond

    Technically, if Steven gets corrupted, there is almost no possible way to bring him back. You can’t really bubble him because he is half human, and if you were to take out his gem, he would become even more dangerous and normal Steven would most likely die instantly because of the corruption.

    possible explanation for Pink-White Diamond and "Corrupted" Steven: White Diamond tried to ruin literally everything in one massive assault on Earth, and therefore Steven did a thing which caused corruption. Therefore Pink-White Diamond. But, it backfired somehow and therefore Wormy Boi

    If This Is True, Then I Think It Would Be Because Of Spinel’s Gem Rejuvenator Because Of All Of The Times He Was Struck With It

  • PikaGamer 0519

    That thumbnail is a cursed image

  • Nannd

    I thought that the rejuvenator could restore corrupted gems, because (from the episode Monster Reunion) the corruption kicked in again when Centipeetle remembered what happened.

  • Kire Gore

    I DID RESEARCH!!! The Worm Monster is a former corrupted Gem that first appeared in "Bubble Buddies". As of "Change Your Mind", the Worm Monster has been uncorrupted, along with the rest of the Corrupted Gems, when Steven and the Diamonds combined their powers at Rose's Fountain. (I just looked up who it is so yeah...)
