5. Iron Man
HAL 5 is an acronym for Hybrid Assistive Limb ... 5. HAL is an artificial powered exoskeleton. In other words, a technological wonder of a suit that is capable of allowing the user to carry five times the weight they could normally carry.
"When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneuron, moving the musculoskeletal system as a consequence." We just copy and pasted that from the official HAL website because it sums it up well enough (apparently just saying, "When you move, this thing moves HARDER!" is too simplistic for the type of people who know how to make cybernetic suits).
Unlike Tony Stark's "Mark VI" Iron Man suit, HAL was not invented for tearing-ass through a war zone, leaving behind a trail of men slowly realizing they just got their limbs torn off by a robot. On the contrary, HAL was designed for factory work, disaster relief, assisting disabled people, and, as the website states, "the entertainment field" which we're sure is code for "Superhuman Endurance Sexbot."
3. Spider-Man
When a young loser named Peter Parker gets bitten by a radioactive spider he becomes endowed with the powers of an arachnid. He can crawl on walls and, just to round out the whole "Spider" gimmick, he invented his own web slingers. Furthermore, he has a spider's ... precognitive abilities? We must have missed that day of science class.
Spidey holds the honorable distinction of being the only character on this list that has two real life technologies currently being researched that can one day bring us a step closer to being riddled with bullets after trying to stop a bank robbery.
First up is carbon nanotube technology, which will basically be Velcro for the "What the fuck is Velcro?" societies of the future. Like Velcro, carbon nanotubes can be formed as a series of hooks and loops that interlock, thereby creating a clinging effect. Unlike Velcro, these hooks and loops are microscopic and can latch on to nearly any surface imaginable, even while underwater.
The second Spider-Man tech that will revolutionize the way we as a society approach cosplaying is more of a theory, but it's a very promising one at that. This theory is based around something called nanoglue.
A group of Rensselaer Polytechnic Institute scientists working with nanolayers (molecular chains of carbon molecules with elements such as silicon, oxygen or sulfur) accidentally found that heating nanolayers of commercially available glue sandwiched between copper and silica, it created a bond that one researcher called "As strong as a motherfucker."
