The Marvel World will never be complete again. After suffering pneumonia for almost one year, the man who created the world of X-Men, the Hulk, Iron Man, Black Panther, and Spider-Man, finally succumb to the battle. He was 95 years old.

Due to his deteriorating health, Stanley Martin Lieber, or Stan Lee as we all know him, was confined in Cedars-Sinai Medical Center on Monday, the place where he eventually died a few hours later. His daughter, JC Lee, confirmed her father's death to Reuters.

Aside from pneumonia, the creator of the legendary comic book also suffered from vision issues. In fact, according to Independent, about two years ago it was revealed that he was already having difficulty reading the comics he once created.

Born on December 28, 1922, in New York City, Lee was known for being the man behind the top-grossing multi-billion film franchise in Hollywood, which is the Marvel Cinematic Universe. This franchise involves 20 highest grossing movies and Avengers series. Lee shared how he always becomes so happy and excited whenever his comics were created into movies especially that he gets to see his creation come alive through them.

Lee's career started in 1939, at a time where comics were only created just for kids. That was when he was accepted as an office assistant at Timely Comics. According to him, he never really have that passion for working and creating comics. He just applied for the position since he was so desperate to have a job to help his parents earn money. He even saw the opportunity as temporary and planned to look for a new job soon. He said, "I had never thought of writing comics."

Several years after, he finally fell in love with what he does. This became his basic reason why he decided to pursue his job and not to leave the company. In 1960's he created the Fantastic Four along fellow artist Jack Kirby. Years passed, other characters such as Doctor Stranger, X-Men, Spider-Man, Incredible Hulk and Black Panther were born.

His daughter JC Lee shared how incredibly dedicated his father was to his fans and for the things he does. "He loved his life and he loved what he did for a living. His family loved him and his fans loved him. He was irreplaceable," she said. She also added how even during hard times his father still shows his passion in creating comics saying, "He felt an obligation to his fans to keep creating."
