Who is the heaviest superhero in the MCU?

Question

Including all technology, weapons, etc., which MCU superhero weighs the most (on Earth, just to simplify things)?

Is it:

• Iron Man, with his mechanical suit?
• The Hulk, with all of his muscle mass?
• Black Panther, with his vibranium suit? (A question about the weight of vibranium can be found in How heavy is Captain America's shield?)

• Thor, with either his Uru hammer or

  Stormbreaker
  

  along with the armor he's always wearing?
  

• Or is it someone else?

Do not count spaceships, huge turbolasers, etc. Suits count, but not vehicles.

Answer 1

Purely based on speculation on size and "apparent" weight, I'd go with:

1. Huge Ant-Man a.k.a "Giant Man"

Ant-Man has shown that he's capable of increasing his size, and apparent weight, he grows to some ridiculous proportions of > 70 ft tall, hitherto known as "Giant Man". It seems that his apparent weight changes and increases with him. I'd put him at at least the 100 tons range. A behemoth by any measure and a definite winner for our category.

2. Bulker-Buster

The Hulk/Bruce Banner duality in my eyes should be considered, one. Therefore, at all times, their weight should be technically combined. Now, based on The Hulk's size and bulk, I'd put him at the 200 kg mark, minimum. Couple that with Mark Ruffalo's approximate 1.73 m measurement, I'd put him at roughly 75 kg (similar build to myself). So, he's definitely around the 1–2 ton range when in the Hulkbuster suit.

Others

The following will fit in a similar category and range:

• Tony Stark + Hulkbuster
• Tony Stark + any other suit
• War Machine
• etc.

3. Groot

"Why don't you make like a tree, and leaf?"

^sorry

Our old tree friend, Groot, is definitely large, and heavy. I'd put him in a naturally high level, since just walking around he looks and sounds like he's at least 200 kg. Coupled with the ability to extend himself and increase his size (and apparent weight), I'd say he has a huge potential to become one of the heaviest superheroes.

4. Peter Quill?

Ok, I'm gonna start stretching this, since for the most part, I don't think we'll get a more accurate answer^*.

Peter Quill is part Celestial, and has access to supposed Celestial powers, namely the white-glowy-power-thingy. Now, as evidenced by Ego in Guardians of the Galaxy: Vol 2, Ego was able to use this power to manipulate the very space and matter around him, to manifest himself as a moon-sized planet, fully-equipped with a shape-shifting body and interplanetary travel ship. Theoretically, and potentially, Quill has the ability to become endlessly big (and heavy). Coupled with his huge ego (lol, yes I did), he's definitely humongous.

^{why stop there?}

Let's see how far we can stretch this thing^@

5. Colossus^#

As far as superheroes go, Colossus is one mega-super-ukulele. Able to manipulate his body to become pure metal. Coupled with his massive size, this dude's definitely a contender for this title. Exactly how big and heavy? Well, I'd put him in the 0.5 to 1 ton range. (Based purely on my minimal ability to judge weights).

6. Beast-mode heroes

Look, I'll make a separate category for heroes that will probably be in a similar category that I'll call "The Beast Modes". These are characters that have a natural... bulkiness. Large enough to beat most humans in size-weight ratio, but not quite big enough to make a dent in the floor as they walk:

• Thor
  • Thor wearing, or holding anything
• Drax
• Cpt. Steve Rogers
  • Cpt. Steve Rogers holding, or wearing anything
• T'Challa
  • T'Challa wearing, or holding anything
• You get the point...

Let's put them at the 100–120 kg range.

@ That's what...

# Hey, you didn't say we couldn't stretch it to the Fox franchise, since Deadpool is somewhat in the middle, I'll happily include this.

Answer 2

Vision. He is able to change his mass at will as shown in Civil War when Scarlet Which forces him to gain mass until he sinks through the floor and when he headbutts antman at low speed to knock him over.

Ant man's ability supposedly works by changing the distance between atoms but that is not represented in the films consistently as his weight is anything from body weight to a feather to fit the choreography. When he is big he always acts as though he is massive. But even in his heaviest it is unlikely to be more than vision.

Thors hammer isn't heavy it is magically unable to be lifted by anything other than Thor. But either way, Vision can lift the hammer so I guess Vision holding the hammer wearing the ant man suit would be the correct answer.

Answer 3

I'm originally thought the heaviest might well have been Tony Stark in the Mk. 2 suit -- that was the first iteration after he was back from Afghanistan, the one built in actual steel. Heavy enough that it crashed through the (seemingly helipad or parking capable) roof of his underground garage when he landed it after the maiden flight -- just before replacing it with the seemingly lighter gold-titanium alloy Mk. 3.

It was pointed out, however (thanks, @OrangeDog), that Rhodes, as War Machine, originally wore the Mk. 2 suit with heavy machine guns or aircraft cannon and missiles added, so that version (War Machine 1.0, Mk. 2 suit plus added weapons) ought to have been heavier than the version that crashed through Tony's garage roof/helipad/patio.

Don't recall any of the other heroes being heavy enough to crash through a concrete surface that can support a Rolls or a helicopter...

Answer 4

I'm just going to throw a few more in here.

First, these two guys don't include armour or growing. These two just go around town weighing this much.

• The Blob (976#)
• Juggernaut (900#)

And the one (or rather the ones) that may weigh the most:

• Celestials (520,000#)

Answer 5

Pretty sure it's Galactus. Anything that consumes planets and is described as "the physical, metamorphosed embodiment of a cosmos" is going to be very massive.
