Mr. Fantastic

Origin

Reed Richards was born in Central City, California and the son of Nathaniel and Evelyn Richards. Reed’s father was a brilliant scientific genius and Reed appears to have inherited that trait. Reed excelled in mathematics, physics, and mechanics and was enrolled in college by the age of 14. He went to multiple colleges including Massachusetts Institute of Technology, California Institute of Technology, Harvard University, Columbia University, and Empire State University. While attending EMU he met and became a roommate of Ben Grimm, the future Thing. They became great friends and Reed shares his dream of building a spaceship himself.

After EMU, Reed continued to go to school at Columbia University,  and he rented an apartment from a woman who's niece was Sue Storm, the future Invisible Woman. Sue quickly fell in love with Reed. Also while attending Columbia University, Reed met Victor Von Doom, who would later be known as Doctor Doom. Doom loved that Reed could rival his intellect. Eventually Doom became jealous of Reed and began conducting reckless experiments that scarred his face.

Next up was Harvard, which is where Reed earned his pH.D. in both physics and electrical engineering, at the young age of 22. After he was done with school he used his inheritance and government funding to finance his project. He began building his spaceship in Central City. Sue Storm would move to this same area and eventually found herself dating Reed again. Reed would ask Ben to pilot the ship for him. The government denied the flight into space so Reed, Sue, Ben, and Johnny decided to sneak onto the ship and they took the ship into outer space. Reed miscalculated and forgot the abnormality of the radiation from the cosmic radiation. The rays destroyed the ship and the crash-landed back on earth. Reed finds out he can stretch his body like elastic at will. Reed adopts the name Mr. Fantastic and convinces the 4 of them to use their powers for good.

Fantastic Four

Reed went on to create much of the equipment for the Fantastic Four. This equipment includes clothing that was made of unstable molecules, allowing the Four to use their powers without destroying the clothing and the Fantasticar. Reed was also determined to find a cure for Ben because he felt all the blame fell on him for causing Ben to become The Thing. Eventually the Fantastic Four would become some of  the Earth’s greatest heroes saving the world countless times. They would battle their greatest enemy, Doctor Doom, many times as Doom blames Reed for causing his facial scars and turning him into Doctor Doom in the first place.

After a long time Reed and Sue finally married and had a son, Franklin Richards. Franklin was born with powers that were unimaginable, leading to him being considered one of the strongest beings ever. When Reed decided to shut down Franklin’s mind so he could not use his powers to destroy the universe, Sue became enraged. She even filed for divorce, but they would reconcile soon afterwards.

During the crisis with Onslaught, Onslaught wanted to take Franklin Richard’s powers and add them to his own. The Fantastic Four and many Marvel heroes sacrificed themselves to defeat Onslaught. They all thought universe was destroyed until Franklin Richards pulled out the pocket universe he had created. Soon after, all reality was restored, but the Fantastic Four had lost their home. Reed would later become a member of the Illuminati and would not tell Sue about it.

Civil War

Reed worked with Iron Man on the pro-registration side and was one of the higher ranking individuals. The choices he made during Civil War would cause a rift between him and Sue, especially the incident when he unleashed his clone Thor, killing Goliath. Sue and Johnny would leave Reed and join Captain America’s group, the Secret Avengers. It was later revealed that one of the reasons Reed sided with the Super-Human Registration Act was because of his uncle. His uncle had picked a fight against the American Government and was imprisoned, ruining his career, reputation and ability to find work. He believed his Uncle was wrong for picking a fight that he could not win, which is similar to Reed not going against the Registration Act because it is impossible to win.

The other reason Richards joined the act was related to a mathematical equation he had been working on. In that equation he used theories to surmise that at the current path humanity was heading in, it would be a matter of time before they all destroyed themselves. He hid the knowledge from his family, and it wasn't until Johnny decided to visit with his brother in law in secret, that this information came to light. He enlisted the help of the Mad Thinker to check his work. The Mad Thinker theorized that the plan was flawed because he didn't include a person's decision, hence an improbable variable. The Mad Thinker's theory was proven when Sue made herself known. She had been there the whole time, and finally knew why Reed wanted the Registration Act to exist. Angry, she stormed off leaving Reed with the Mad Thinker.

After Civil War, Reed wrote a letter to Sue asking her to come back, and after receiving it, Sue returned to the Baxter building. In an effort to reconcile and fix the emotional strain their marriage had endured during the Civil War they decided to take a leave of absence. In their place, Storm and the Black Panther would take over.

He took Sue to one of the moons of Saturn to try and rekindle their love, as well as give her their first true honeymoon, since they never had one. While there Reed discovered a strange object and teleported back to Earth in order to gain information on it. Unbeknownst to him, the Frightful Four commandeered the ship with Sue still within and kidnapped her. They're only goal was to destroy the Fantastic Four.

World War Hulk

During World War Hulk, Reed Richards, with the help of Sue Storm and the new Fantastic Four, tried to stop the Hulk by creating a hologram of the Sentry to calm the Hulk down. The plan failed and led to the Fantastic Four's defeat and Reed's capture. When the Hulk built the Gladiatorial Stadium in New York, Reed was forced to fight Tony Stark to the death.

Secret Invasion

Prior to the events of the Secret Invasion, the Illuminati conveyed a meeting to investigate the corpse of a Skrull impersonating Elektra. It wasn't until Black Bolt voiced his opinion that things weren't looking good for them. Black Bolt then turned into a Skrull and attacked the Illuminati to retrieve the dead Skrull. After it was killed by Namor, the Illuminati separated, perhaps for the last time, because any one of them could also be a Skrull and therefore they could trust no one from now on. In his laboratory, Reed and Hank Pym were doing an autopsy together on the dead Skrull to find out why the Skrulls had become undetectable. When Reed finally found out, Hank shot him from behind and revealed himself to be a Skrull.

He was later being torture in a skrull ship in orbit, and was later rescued by S.W.O.R.D agent Brand, who later used the information to find out a way to discovered who was a Skrull and who was not. He and agent Brand travel to Savage Land, where Richards fires an odd  weapon, who reveals who were skrulls among the heroes there.

During the Secret Invasion it is revealed that a clone of Reed Richards is possibly the reason the Skrulls know how go undetected. Reed is first shown in a room meeting with the other members of the Illuminati. The members are discussing there escape from a Skrull ship, as well as if they could be hiding undetected. Once they find their powers seem to be failing, tempers begin to flair and it is revealed that the Charles Xavier in the room is a Super-Skrull and the rest of of the illuminati are just clones. The clone of Reed Richards is viewed by one of the Skrull scientists, by the name of Dro'ge, as having the key in his mind for what they wish to acquire. A second clone is subjected to physical and mental torture, which fails. A third clone is then placed into a recreation of his bedroom. The Skrulls then manipulate this Reed by looking like his loved ones, and manage to get him to write down some kind of equation that is hinted at being the answer to how they remain undetected. 

Powers

Reed can also change his appearance and even imitate an inanimate object. He can concentrate his elasticity into one area of his body. For example, it can all go to his fist, making it an effective offensive weapon. This can increase his strength and size considerably. Though he has many great physical feats, his intellect is also considered a power of his. He is one of the smartest in the Marvel Universe, showing himself to be even as smart as alien civilizations. Because of this, mind control is useless, though when it does affect him, it wears off more quickly than on an average human. He is not flawless however, as he has tried many times to revert the Thing back to his normal human form. He also indicates that he can not understand magic. Later in life, he also earned a Black Belt in Judo.

Reed, at one time, was the possessor of the Power Gem.

Alternate Realities

In the alternate reality known as the Age of Apocalypse, Richards attempted to evacuate a large group of humans from Manhattan when Apocalypse came into power. Along with Ben Grimm as the pilot and his friends Johnny and Susan Storm as crew, Richards used one of his prototype rockets to fly off the island. Unfortunately, an angry mutant sabotaged the launch and both Reed and Johnny sacrificed themselves to let the others blast off safely. Reed Richards did not have any powers in this reality before he died, as he never was bombarded with cosmic radiation in space.

Reed Richards of Earth-One Dimension Away

In this Universe, possibly either Earth-615 or Earth-617, Mister Fantastic and Jack Storm (The Human Torch) were a (presumably) happily married homosexual couple whose world was very different from Earth-616, the most notable differences besides the way Reed and Jack's lives turned out was that the Captain America and Black Widow of this reality were identical to their Earth-1610 counterparts. It all ended in disaster however when The Marquis of Death and Clyde Wyncham arrived in their Universe and within a matter of hours wiped out every living thing on Earth and beyond. As The Marquis explained how Reed's sister-in-law (Susan) and his best friend (Ben) died in detail, Reed demanded to know why they had committed this atrocity and with that The Marquis said "You Live. We kill...that's just the way things are" and then proceeded to tear Reed's heart from his chest and consumed it. It is not known what kind of powers Reed possessed in this reality but because of the mechanical gauntlets he wore one could assume that the Reed of this reality did not have stretching powers like his Earth-616 counterpart and had been given some other ability the day they all gained their powers that required the gauntlets in order to control it.
