The Hulk

Bruce Banner worked as a scientist on the gamma bomb project when he heroically saved a young man from exposure to a nuclear blast. Unfortunately, the exposure to gamma radiation changed Banner's cell structure, causing him to transform into a raging green monster (known as the Hulk) when he became angry.

My Opinion - The Hulk, the most powerful super heroes, can't control himself so he will harm everyone around him that's why Bruce Banner tries to stop being the Hulk by testing many medicines to his body but it doesn't work.  

Ant-Man

Though a brilliant electronics expert, Scott Lang had made his share of bad decisions. Having served time in prison for burglary, Scott would return to his life of crime in order to save his terminally ill daughter, Cassie. Stealing the Ant-Man suit from Hank Pym, Scott would use the suit to save Dr. Erica Sondheim, the only doctor capable of saving Cassie from her heart condition. Once he realized that Scott was only trying to do the right thing, Hank Pym not only let Scott keep the suit, but gave him his blessing as the brand new Ant-Man.

My Opinion - Ant-Man is the only one in Marvel who had the power to shrink himself to the size of an ant and return to normal . He can also shrink to sub-microscopic size, and thereby enter the countless "subatomic universes".

Deadpool

Wade Wilson received a healing factor that prevented his cancer from killing him. Wade soon escaped the program and became a freelance mercenary using the name Deadpool, working for various criminal organizations. At times he has teamed up with heroes as well, but these attempts at "being a good guy" rarely stick for long.

My Opinion - Deadpool is the most hilarious character in Marvel Comic. His ability is undead even you cut his head off. you can watch him in the movie on 10th February this year.

IRON MAN

Wounded, captured and forced to build a weapon by his enemies, billionaire industrialist Tony Stark instead created an advanced suit of armor to save his life and escape captivity. Now with a new outlook on life, Tony uses his money and intelligence to make the world a safer, better place as Iron Man.

My Opinion - Iron Man is kind like a robot but the man is inside it. This character is very important to the movies because he is going to fight with Captain America in Civil War Movie.They both are the main characters.

CAPTAIN AMERICA

Vowing to serve his country any way he could, young Steve Rogers took the super soldier serum to become America's one-man army. Fighting for the red, white and blue for over 60 years, Captain America is the living, breathing symbol of freedom and liberty.

My Opinion - Captain is just a human so I don't like him much because when compared with Iron Man in The Avenger Movie he would seem like a normal people, and helpless.

SPIDER-MAN

Bitten by a radioactive spider, high school student Peter Parker gained the speed, strength and powers of a spider. Adopting the name Spider-Man, Peter hoped to start a career using his new abilities. Taught that with great power comes great responsibility, Spidey has vowed to use his powers to help people.

My Opinion - Spiderman is the best superheroes in Marvel for me. He is strong ,smart ,fast. and also his web could do many things.

Nightwing

Nightwing (Dick Grayson) was the son of John and Mary Grayson. The family was a circus act that performed at Haly's Circus. One night Dick sees his parents murdered by a mafia boss who wants revenge on the circus's owner, Haly, and coincidentally Bruce Wayne, (a.k.a. Batman) witnesses the terrifying act and offers to take the young orphan by his side remembering that he was once like Dick in his current state. Dick had keen detective skills already and soon figured out that the billionaire playboy Bruce Wayne was the Dark Knight himself. Bruce agreed to take Dick under his wing as the first Robin out of many. Many years passed and Dick became too old to stay under Batman's care and soon took a superhero name of his own, Nightwing.

My Opinion - I prefer Batman to Nightwing because Batman is original and was the guy who taught Dick to fight. By the way Nightwing once was Robin before. Then he changed his name to Nightwing.
