Who is the biggest being in Marvel? It’s a super interesting question. Not least so because the answer is not who you might think it is. Big shout out to @sir_superhero on TikTok for the idea. So, without further adieu, lets get into it.
Technically, Eternity is the biggest being in Marvel. He is a living manifestation of the Universe. It really doesn’t get much bigger than this guy. Here’s the problem though. He’s a metaphysical being, meaning he doesn’t really have physical form. Therefore, he and all other metaphysical beings are automatically disqualified from this list. It just wouldn’t be fair.
Next up in the disqualified category is The Annihilation Wave. The Annihilation Wave is a huge army made up of an uncountable number of of insects who all share a single hive mind. Technically, this could be considered as one organism but in the spirit of the question, The Annihilation Wave is also going to be disqualified from this list.
The Biggest Being in Marvel
Now that we have the cheaters out of the way, we can get to the real contenders. The most popular answers that come to mind when thinking of physical size in Marvel is usually either Galactus or Ego the Living Planet. Surprisingly, neither of these characters are even close to being the biggest being in the Marvel comics.
The first REAL contender is The Black Winter. The Black Winter is a character who eats Universes in the same way that Galactus devours Worlds. And he actually does have some sort of physical form. Although it’s said that he “eats” universes, he more absorbs them rather than eats them. Still impressive stature nonetheless. If you want to get a sense of how big this guy is just look at the image below.
See that little glowing guy at the bottom? That’s Galactus. The guy that eats planets. Looking like Antman. So yes, The Black Winter is definitely ONE of the biggest. But he’s not the biggest.
Yes, you read that right. The Cancerverse. There is an entire universe in Marvel comics called The Cancerverse. It is absolutely horrifying. In this universe there is no more death. Nothing can die. Every organism just keeps growing and reproducing at an exponential rate until eventually all life converged into one unified organism that was the size of the universe itself.
And yes, The Cancervserse is indeed classified a singular organism. Making it the biggest being in Marvel. Probably not answer you were expecting when you clicked into read this article. But now you know. You are burdened with glorious knowledge.
Biggest being in Marvel (MCU)
In terms of the Marvel Cinematic Universe, our heroes haven’t really crossed paths with with anybody on the kind of scale mentioned above. The largest would be Dormammu (Doctor Strange) but again, he is not someone that has a physical form so is disqualified from this list.
The biggest being we’ve seen in the MCU to date is Ego the living planet (Guardians of the Galaxy Vol.2) but this will no longer be the case once we’re introduced to The Celestials in The Eternals movie this summer.
