QUICKSILVER

Quicksilver has the superhuman ability to move at great speeds. In most depictions, he is a "mutant", a human born with natural superhuman power. He is the product of genetic experimentation by the High Evolutionary. Quicksilver most commonly appears in fiction associated with the X-Men, having been introduced as an adversary for the superhero team. 

My Opinion - Quicksilver is similar to The Flash in DC Comic. They have same power and ability. Quicksilver is the fastest one in Marvel however I think The Flash is faster because he is fast until able to travel to other space.

THOR

As the Norse God of thunder and lightning, Thor wields one of the greatest weapons ever made, the enchanted hammer Mjolnir. While others have described Thor as an over-muscled, oafish imbecile, he's quite smart and compassionate. He's self-assured, and he would never, ever stop fighting for a worthwhile cause.

My Opinion - Thor is trained in the arts of war, being a superbly skilled warrior, highly proficient in hand-to-hand combat, swordsmanship and hammer throwing. I like him when he throw the hammer.

WOLVERINE

Born with super-human senses and the power to heal from almost any wound, Wolverine was captured by a secret Canadian organization and given an unbreakable skeleton and claws. Treated like an animal, it took years for him to control himself. Now, he's a premiere member of both the X-Men and the Avengers. Wolverine is a mutant who possesses the ability to regenerate damaged or destroyed areas of his cellular structure at a rate far greater than that of an ordinary human. The speed at which this healing factor works varies in direct proportion with the severity of the damage Wolverine suffers

My Opinion - . he can fully recover from an ordinary gunshot wound in a non-vital area of his body within minutes. So he just like Deadpool

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.
