The truth of the matter is very different, however, since Reed Richards is actually the farthest thing from an egotistical genius. The Mister Fantastic title has actually been the subject of decades of debate among fans, because, although they know Reed isn’t that arrogant, the name itself does feel larger-than-life. The comics offer many explanations, since Reed has been around ever since Stan Lee and Jack Kirby created the Fantastic Four in the 1960s, and the Mister Fantastic name has had many explanations ever since, and they all fit the character like a glove.
The Comics Give Many Explanations for Mister Fantastic’s Name
A man choosing to be known as Mister Fantastic does seem to be full of himself, but, in Reed Richards’ case, that’s just not it. Over the decades, Marvel has explained the origin of his hero name a few times. The most widely known came in 2002’s Fantastic Four #489. While telling his daughter Valeria a bedtime story, Reed reveals that he doesn’t like the name Mister Fantastic, but it helps the public see the Fantastic Four as heroes and not freaks, evidencing his guilt about the accident that gave him and his family their powers.
Finally, another great explanation is in Chip Zdarsky‘s Captain America #1. Steve Rogers (Chris Evans) meets with Reed to gather intel on Doctor Doom (Robert Downey Jr.), but they are interrupted by fans who recognize Mister Fantastic. Reed immediately changes his facial features to mislead them, and then explains that he chose Mister Fantastic because “people expect someone bigger than life with a name like that.” “I can walk around and, with a little ‘self nip and tuck,’ I just disappear.” Now, those three are very Reed Richards reasons for a name like that.

Jack Kirby, Stan Lee, and the Original Meaning of Fantastic
Among fans who do understand the character, however, there has been a long debate about the usage of the term “fantastic” by Reed, with some even arguing that the original Fantastic Four comics may have even changed the whole meaning of the word. “Fantastic” comes from “fantasy,” and some argue that the success of the original comics could have started to change its meaning into the positive superlative that nearly everyone uses it as nowadays. Marvel itself released the Amazing Fantasy anthology at the same time, which could hint that their intentions with naming the Fantastic Four (and, therefore, also Mister Fantastic) could be just to allude to fantastical powers.

Reed Richards Would Never Choose a Name Like Mister Fantastic Out of Ego
If there’s one thing we can be sure about Mister Fantastic’s title is that Reed Richards didn’t choose it out of ego. In First Steps, Pedro Pascal does a great job of portraying Reed’s character as someone who is immensely intelligent and, as such, feels responsible for protecting not just everyone he loves, but the whole world. Although his “fantastic” powers aren’t seen that much, Reed’s true superpower is his intellect, and, yet, he never uses it to promote himself, but rather to focus on the Fantastic Four the task of keeping the world safe.

In the comics, there is indeed a hint of pride in his achievements and intellect. Otherwise, he wouldn’t like being called “the Smartest Man in the World,” or have created a whole council with multiversal variants of himself to solve problems. If he truly wanted to feel superior, he would probably have thought of something different, like “Doctor Fantastic,” since he has countless academic achievements. His nemesis, Victor Von Doom, is just as smart and certainly likes his own villainous name, Doctor Doom, for example.
