William Manton / The Suit
William Manton is an incredible intellect, in more ways that one. He has often been said to be one of the universe's greatest polymaths, having dabbled in every area of science, from astrophysics, to quantum theory, to chemistry, to biotechnology, and many more fields, some having even been begun by him himself. One of his greatest achievements is working out a way to suppress nearly any kind of energy, and turn it into power, with the right machine.
He was born a normal boy save his enormous intelligence, but upon his sixteenth birthday, he was changed forever. These changes included him being rendered invisible, even to a thermal camera, his presence only defined by a gap in air molecules. He can still interact with the world, but in an unusual way. His own body cannot properly touch anything solid, in fact it can only even be harmed by things non-solid, such as gases, liquids, lasers, et cetera.
The way he does interact through the world is the Suit. It is that which through which he speaks, and it is fully able to touch and interact, with one small difference - to put it simply, it is both the unstoppable force and the immovable object. Its strength is immeasurable - it has before pushed two planets apart, with aid from its other ability, which is its utter invincibility, and ability to spread that invincibility to anything it touches, such as the ground upon said planets. Normally, its maximum size of invincibility spreading is around fifty metres, but that day The Suit's ability to share was augmented a thousand-fold by a complex setup of power-multiplication loops set up by The Suit / Manton.
If you're wondering, this character was inspired heavily by the character William Manton and the Siberian, from the webseries Worm, by WildBow.
