As the leader of the world's most famous super-team, Reed Richards--aka the one and only
Mister Fantastic--is arguably the face of the Fantastic Four and front and center in the FF's dealings with both heroes and villains as well as the general public and the government. And so taking account of the fact that the PPC has already thrown a spotlight on Ben Grimm, the Thing, by profiling our favorite
"Clobberin' Time" moments, Mister Fantastic was an easy choice for this sort of post which takes him out of that lab of his and lets him stretch his legs. (Ha ha! Get it?)
In addition, since we only rarely get to hear Mister Fantastic's action name in use when in the field (we can say the same for the Invisible Girl/Woman), we're only going to refer to him as Mister Fantastic for the duration, just to get an idea of how that might have looked and "sounded" in print. We may all become tired of it before long--probably because it's hard to imagine someone as level-headed and unpretentious as Re... whoops, Mister Fantastic to have chosen "Mister Fantastic" as the name for himself right out of the box. Let's also hope that it wasn't Mister Fantastic who coined his team's name*, since it conveys the disturbing implication that he wanted it to be "Mister Fantastic's Fantastic Four."
*It had to be one of the team, given that no one in the general public recognized the name when it appeared in the team's first flare which signaled that it was time to go into action for the first time. Michael France and Mark Frost, writers of the 2005 film, seem to think that person was Johnny Storm.
To cut to the chase, if I had to pick my favorite Mister Fantastic scene, it would be when a so-called monster was roaming the streets of New York, forcing Mister Fantastic to interrupt a critical experiment that involved returning the Thing to his human form in order to deal with the crisis. In this scene we get the complete Mister Fantastic package--decisively acting to save lives, assessing the situation, multitasking when one of his team is in danger, and setting his priorities on how to handle things from here.
