It's a symbol of hope and justice - and the idea that those with superpowers and special skills alike are still working for the good of mankind. There have been a few different versions of the shield after a decade of movies, and it's even changed hands a few times, which leads to even more questions about the iconic piece of equipment.
Remember that vibranium is the incredibly rare and powerful metal that Wakanda is built on a mountain of.
Enough was discovered by the U. In Marvel comics, there might be variations of the shield's appearance depending on the artist or the storyline. That's very much true in the MCU as well. As Captain America's story changes, he gets different shields. His first shield in the MCU is a prop during his tour to promote war bonds, though he does take it into battle. Captain America's next shield would be the one he used in most of his movie appearances, creating the iconic circle with a star in the middle in his red, white, and blue color scheme.
That shield would eventually be left behind for a time , and he got a pair of retractable shields in Wakanda before getting his original shield back in time for his big battle with Thanos. Though Tony Stark did work on a new shield for him, that one was never used. That means Captain America has only used four different shields in the MCU, though it might have looked like more to the audience.
Unlike Thor's hammer, anyone can pick up Captain America's shield. The question is whether or not they know how to use it the same way. Several allies of Steve Rogers have been able to pick up the shield in the middle of a fight and successfully wield it. In some cases, the allies that use his shield aren't allies yet. Now for the reflection. This is trickier and my method only works in 2-D so the shield moves in the x-y plane.
If I create a wall in VPython Glowscript , there are some properties of this object which is technically a "box. Here is a diagram showing the shield colliding with the wall.
The two important vectors are the velocity and the axis. You can find this angle by first finding the dot product between these two vectors and using the following relationship:. Finding the dot product for vectors is simple if you know the vector in component form the x,y,z components.
It's also simple to find the magnitude of these vectors. So, in the end you get the angle between these two vectors. Oh, it's even easier since both the dot product dot and the vector magnitude mag are built in functions in VPython. Now that I have the rotation angle, I need to rotate the vector. I can use the rotation matrix in 2-D. Here is the xkcd version of the rotation matrix. It's funnier than the actual matrix. So, that's pretty simple.
Now let's put it all together. Actually, this is sort of like a video game. So I made a video game. Just drag the arrow to pick the direction you wish to aim the shield. The goal is to bounce the shield off the wall and hit the blue circle. If you successfully hit the circle, it turns yellow. If you miss, just press play and try again.
The code is a little messy but you can check it out here. I'll probably make a screencast in which I go over the different parts of this program. Cap has even used it to absorb the impact of falling from a skyscraper and absorbing the energy of his landing with the shield escaping serious injury. The shield has also taken blows from Thor and Mjolnir with Captain America's fighting skill allowing him to roll with the impact escaping serious injury. The nigh-indestructible shield has been broken five or six times, in continuity, by the Molecule Man, Doom, imbued with the Beyonder's powers, Thanos, wielding the Infinity Gauntlet, Thor using the Odinforce and by the Serpent, brother to Odin.
Its breaking is usually a monumental event and when its replaced or repaired it is often by the same force that destroys it. There are numerous retcons in the Marvel universe where the shield was thought to be broken and found to be a replica instead.
When the shield is thrown, edge on, the vibranium alloy allows the shield to resonate and continue bouncing from object to object when struck on the side. The shield will continue bouncing, if thrown properly until it is either caught amid flight or strikes an object not capable of resisting the shield well enough to continue on its way.
With sufficient training, Captain America has learned to be able to throw the shield so it returns to his hand, apparently effortlessly.
Technically, it is to be assumed the Taskmaster could do it since he can photographically copy the reflex actions of any trainable skill. Though it may appear that Captain America's shield returns to his hand via magical means, it does because of his highly trained and finely-honed skill at throwing it. Coupled that skill with his enhanced superior agility and mental acuity as well as the unique metallurgical properties of the shield itself and you have the unique defensive and offensive properties of Captain America's shield.
Nearly indestructible, it can be used defensively as a protective device and offensively only in the hands of a skilled user. Few on Marvel's Earth have the capabilities and experience throwing the shield of Captain America. From the Wikipedia article:. The vibranium in the shield grants it unusual properties, allowing it to absorb virtually all of the kinetic impact from any blows that the shield receives without injuring Rogers in the process.
The vibranium is also a factor in the way Rogers throws his shield: he often uses it to ricochet around a room and strike various opponents with little loss of velocity in its forward movement after each impact. Given his enhanced strength and intelligence, he can calculate where he needs to hit something and the ricochet paths in order for it to return to him. No on the Captain America glove there is a magnet that is so strong.
The magnet can only attract the shield. So that's why the shield come back to him. Sign up to join this community. The best answers are voted up and rise to the top.
