In the S02E14 of Marvel's Agents of S.H.I.E.L.D., Coulson took Skye to a secret seclusion retreat facility of S.H.I.E.L.D. which was built by Bruce Banner.

In the next episode, a fist dent on Vibranium-lined Honeycomb wall was shown:

fist dent

Whose fist dent is this?

I debated about this in comments of this question. I believe that the fist dent was made by Captain America (others believe that it was Hulk's) because Coulson told Skye that Rogers spent a few weeks there after he was defrosted. It doesn't prove the dent was made by him, but punching in anger is his style (it again proves nothing). The facility was designed to withstand Hulk-size force, but it can be generic specification to deal with strange guys. It doesn't prove that Banner stayed there. And, even if he stayed there, it's possible he didn't go haywire to create dents all over the place. Also, it's not Hulk's style to punch on wall. He just cries, throw objects, and run here and there when he is angry.
In short, we can't conclude the answer logically with verbal data. Or, if you can, please answer.

Can you compute and prove using graphics that that fist dent was made by Captain America or Hulk or some other guy?

    It's clearly a Hulk-sized fist print. We know Hulk's alter ego built the cabin. Why is this even a question? If it walks like a duck and talks like a duck... (And like phantom42 said, if you think punching a wall is somehow out of character for the Hulk, you clearly need to watch/read more about the Hulk.)

  • Episode details and dialogue indicate the Hulk tapped the wall. And it isn't vibranium neither.

  • @Ihor Give me the dialogue which indicates that. That can be answer.

This discussion should refocus to answering - Why isn't it the Hulk? Are really big hands an allergic reaction spreading amongst the players in the MCU? Oh no, Capt. Kirk had them in Star Trek after the injections given by McCoy! And his tongue swole too. Maybe there are big lick tracks somewhere in the cabin. Maybe the maid punched the wall because the tip envelope was light. Discuss.

There is no way a normal sized human left the dent there with their fist.

Consider the size difference of Skye's fist versus the dent in the wall.

Skye holding her hand up to the fist dent in the wall

Skye has her fist on a slightly odd angle/bend, but even if we assume that her fist is as big as her entire fist and wrist, her entire fist still fits in just a few of the finger joints in the dent.

Same image as the previous one now with red outlines!

A normal-sized human (e.g. Captain America) with immense super power could conceivably punch hard enough to dent the Vibranium, but the force behind the punch would only affect how deep the impression was, not the length/width of it.

So, given that a normal sized human could not do this damage (even if he's wearing "punching gloves", who left it?

I asked Maurissa Tancharoen, one of the head writers and producers of the show.


@MoTancharoen Any chance of settling this for us? Is the fist print Hulk's? Who else could possibly do it?

While not 100% explicitly saying, "Yes, it was the Hulk", she does say that my conclusion is "astute".


@phntm42 Seems like an astute conclusion...

So, to sum up:

  • The fist print is too large for a normal human
  • The house is described as being built for/by (at least in part) Bruce Banner
  • Coulson mentions the place being built to withstand Banner
  • The head writer/producer says that the Banner theory is a good/accurate assessment.

The fist print is from The Hulk.

  • You are assuming that Captain America punched bare-handed..

    @SS-3.1415926535897932384626433: as opposed to punching with gloves. Metal gloves, presumably. That are shaped like big fists. Apr 16, 2015 at 20:54
  • @PaulD.Waite Vibranium gloves maybe..

In the next episode when Alternative SHIELD finds out where Skye is they say:

The one that Banner built?

This cabin was constructed by Bruce Banner, and it is assumed that as the Hulk he is the one who punched the dent in the wall. This makes sense particularly when you consider how large the dent is. It is much larger than a normal sized fist, which is what Captain America has.

Here we see Captain America's original steel shield after being punched by Red Skull (who basically has the same strength as him). You see it is a normal sized fist print.

Red Skull's fist dent in Captain America's original shield

After Banner abandoned it, the cabin apparently became a safe house for people with powers who may not have total control over themselves yet or were initially feared by SHIELD.

The only other person I could conceive of making an impression this large would be Abomination, but I highly doubt SHIELD would allow him to stay at a cabin somewhere.

    Another point: Rogers is strong, but are we really saying he's strong enough to put an impressive dent in a wall specifically designed to contain the Hulk? Apr 15, 2015 at 17:06
  • I have mentioned in the question that the cabin was built by Banner and it proves nothing. Banner could just have assisted S.H.I.E.L.D.

    "Hulk just cries and run here and there when he is angry" I'm not sure you've ever watched anything with The Hulk.

    @SS-3.1415926535897932384626433: “1. He stayed there. 2. Punching in Anger is his style.” And 3, HIS HAND IS NOT THAT BIG. Apr 15, 2015 at 20:36

Look, not only is the dent big enough that I'm reasonably certain that Hulk left it, when I examine it more closely, something else becomes pretty pro Hulk.

The diameter of the fingers in the dent are at least 1 1/2 inches wide. Hulk or others like him are the only beings with digits that massive coupled with that much raw power.

  • You're assuming that Captain America punched bare-handed. There are things called Gloves in the world..

Obviously it was Hulk's. It can be seen by the size of the fist and it is mentioned in the conversation that was between agent Weaver and another agent in the same episode where one agent informs agent Weaver that Skye's location is "The Retreat". Her reply gives us the answer as she says;

Why would Coulson take Skye to a place built by Banner?

That is Bruce Banner: The Incredible Hulk.


I believe that The Retreat is the same cabin we see at the end of The Incredible Hulk, except with a few modifications. When I first saw the dent that Skye uncovered in the wall, it immediately reminded me of that cabin. Bruce Banner could have possibly made contact with SHIELD and Fury had the place built. Whether it was to contain him if he got out of control, or if it were a place for Banner to learn to control his anger, I don't know. I suppose it is also possible that Banner built it then Fury added some modifications to it so it would be more like a safe house, like it is now.

  • ...but whose fist dent is it?

In the Agents of S.H.I.E.L.D. episode 2x15 - One Door Closes at time index 27:50, Barbara "Bobbie" Morse was discussing Skye's whereabouts with the governing counncil of the Real Shield.

Agent Weaver said about The Retreat, that Coulson was

... taking her to the house that Banner built ...

indicating that Dr. Bruce "The Hulk" Banner built the hut, and it can be guessed he caused the indentation in question.

  • This does not really seem to provide much of an answer to the question. What information can be found by watching the video that you mention?

    Sep 29, 2016 at 9:42

I think it's the cabin that we saw at the end of The Incredible Hulk, when it was still Edward Norton playing him. Therefore, it is probably the Hulk's fist.

  • I have taken the liberty of explicitly stating what your answer appeared to be here. If that wasn't the case please edit your post to clarify exactly whose fist you believe this to have been.
