The Silver Surfer is one of the more powerful super heroes, though he wasn't born that way. His home world is Zenn-La, and while young, he hungered for a more exciting life. Within time, an alien entity known as Galactus, an evil planet eater, was approaching his home world. Galactus agreed to spare their world, only if Norrin Radd (his real name) would search for other worlds for the evil giant to engulf.
Galactus then transformed Norrin's skin into a silver colored material, and crafted a board which Norrin would be able to use to trek the universe in search for planets. Galactus also made it to where the Surfer wouldn't care for life, and thus when the Silver Surfer found planet Earth, he notified his master.
Once he arrived on our planet, he noticed that others, most notably the Fantastic Four, were filled with benevolence toward each other. Not only that, but he also saw their courage, and how they wished and did good to save others. Once this happened, his emotions that he felt prior came back, and vowed to do good. However, Galactus was already coming to devour Earth. Thankfully, Reed Richards, also known as Mister Fantastic of the Fantastic Four, created a weapon that scared Galactus off, though not before trapping the Silver Surfer on Earth, never allowing him to leave.
Despite being safe on Earth, the Silver Surfer desired to once again travel through space. Knowing this, Richards found a way to allow him pass the barrier that Galactus had made, and he was once again able to travel the universe. On many occasions, however, he has returned back to our planet.
While this isn't the last Fantastic Four comic, this is the final one written by the series' creator Stan Lee, who hasn't made a FF comic in ages. For some more preview images, click the link below -

The Thing is part of the Fantastic Four, and has incredible strength. During the drastic crash that would change all four people's lives for ever, Ben Grimm (the real name of The Thing) seemed to have had the most dramatic change in appearance - While everyone looked virtually the same in their regular form, Ben Grimm always looks like a large orange walking rock mass.
Susan Storm Richards is one of the most valuable Fantastic Four members as she can 1. Turn invisible, 2. Generate a force field around her or others, and even 3. Fly through the air by projecting force fields underneith her. She became the Invisible Woman after, along with her brother Johnny Storm, her husband Reed Richards, and friend Ben Grimm, got exposed to cosmic radiation while trying to travel to different solar systems. Ultimately their plan failed, though they did obtain amazing powers which would greatly help them save humanity.
The Human Torch (Johnny Storm) is one of the members of the Fantastic Four, and is the brother to Susan Storm Richards. He has the ability to engulf his body in flames by will without being burned, and can also fly by using his fire as a boost.
Mr. Fantastic (real name Reed Richards) is one of the first super heroes that Marvel created in the sixties when they decided to create superhero comics once again. He's the leader of the Fantastic Four, and has the ability to shapeshift - most notably being able to stretch to great lengths.
