No, it's not Fedor of MMA or Bruce Lee. It's Morihei Ueshiba, the founder of Aikido. He was said to have: -Been shot at and gave out a loud yell which caused the bullets to stop and drop in front of him. (not saying I believe that but........ reports say he did). - Showed real ninjutsu skill by disappearing and appearing somewhere else. It's been said that nobody else, not even another ninja and not even the best ninja ever, could actually do this. - Was able to throw people and even 'pin' them without touching them. People claimed they always felt something, but Morihei never touched them (apparent video of this). - Was able to throw a dozen men down to the ground at the exact same time (apparent video of this). - Was attacked by several american troops at the same time and yet not one of them could touch him. It ended with the american troops getting tired and calling it quits. Morihei did not try to hurt any of them and just let them keep trying to get him. Oh, and he was not ready or knew about this attack. It was planned by the americans as they heard Morihei was undefeatable and nobody could touch him and beat him, even in groups attacking at the same time (apparent video of this). - Was attacked by several high ranking kendo swordsmen at the same time. All were defeated without even touching Morihei even once with their wooden swords. - After some deep spiritual meditation and supposed talking with a spirit of a founder of a specific weapon, mastered the weapon overnight so as to teach a student the weapon (as the student had asked Morihei to learn the weapon). - Claimed to see red lines just before an attack so that he always knew the attack a split of a second before the attack. - Claimed that God's spoke to him warning him of an attack (so he was always ready). An example that a student gave was that when he and many others were training with Morihei, he was planning on doing a sneak attack on Morihei and just when he was about to attack Morihei, Morihei's eyes grew wide open and Morihei looked at the student knowing his intentions. The student obviously never attacked Morihei. - Once he reached a certain level at around age 40 or 50, it was said nobody was ever able to touch him again unless he let them. Even in a crowded shopping district or train, he would somehow never bump into anybody (and nobody bumping into him). Probably why the kendo swordsmen, the american soldiers, and even his own students (among everybody else) couldn't lay a hand on him. - He was able to disarm any attacker with any weapon. - Had people, even the police, and in groups, pin him any way they wanted and to try and keep him pinned. Morihei always broke free instantly. People described it as some type of power they just couldn't resist. There are other things as well such as Morihei defeating top Judo fighters instantly (many who became Morihei's students afterwards), and so many other things. Again, I don't know what is true and what isn't, but there are stories with Morihei that I just can't find with any other martial artist that if they're true, even just half of them, then Morihei is, in my opinion, the greatest martial artist of all time. If you think somebody else, please mention who.
