Between the time it took for him to get on the elevator alone and reaching the first floor, Clark had changed from his work attire to his Superman suit, loosing no time in rushing through the lobby and immediately flying high into the sky. He may have paused for just a moment outside Lois' office window, but that was pretty typical of Superman.
But this time, Lois looked concerned.
Clark continued his flight into the sky, thinking about the concern on Lois' face as she looked at him through the window of the Daily Planet. As the top reporter on Superman, Clark had seen Lois in scarier situations than this where she had never faltered, so he knew this had to be pretty big if it was shaking her nerve.
As he reached Earth's atmosphere, he used his telescopic vision to hone in on the meteors. They appeared to be some sort of shining green color, shining as if made out of polished emeralds despite their rough, rocky texture. They were fairly sizable, too; the smallest was about the size of a beach ball, give or take, and the largest looked like it was as wide as a football field, easily able to crush multiple buildings in one go.
This really was serious.
Continuing to rush towards the meteors, Clark started to feel a tingle on his skin. As he quickly got closer he felt the sensation go deeper, becoming less like goosebumps and more like a dull ache in his muscles.
It wasn't until he smashed his fist into the first meteor seconds later that it dawned on him.
Kryptonite.
As Clark blasted through the rock his fist suddenly cramped, a dull throb starting in his hand and slowly creeping up his arm. It quickly spread into his shoulders, from their branching out into his chest, his abs, his legs, his back and his other arm. Even his head wasn't spared the dull throbbing as he could feel the blood pumping in his ears.
That's when the painful throbbing changed into a strange sort of soreness, the kind that almost felt good. As if he had been working out and got a good pump. He felt all the muscles in his body tense as he suddenly felt his body expand, going taller by at least four inches. The sensation didn't last long, and the strangely good ache disappeared immediately. His suit, already designed tight, seemed to be doing its best at accommodating his new height.
Breathing heavily after the experience, Clark looked down at himself in shock. He'd never had that sort of reaction to kryptonite before. This had to be some sort of new, rare type. So far, his body seemed to be exactly the same save for the added height.
But Clark was so preoccupied with his sudden growth that he didn't notice the larger meteor hurdling toward him until it smashed against his back, immediately cracking and falling away into harmless fragments.
This time Clark recognized the dull throb that immediately spread over his back and shoulder muscles simultaneously. It spread through his body more quickly than before, and his breathing grew quick as that pleasurable ache seeped into his muscles and his bones.
He gasped as this time he felt his back lengthen independently of the rest of him, his lats and chest growing proportionately to the added length. He felt his head follow suit, and suddenly he realized that he wasn't just growing taller but was growing proportionally taller. If this kept up, he'd be a giant.
His arms quickly lengthened, and Clark watched as his biceps stained the cloth of his suit, stretching it as far as it could go. His legs both lengthened and filled out, and Clark groaned as the front of his suit was suddenly stretched too tight over his groin. It wasn't an entirely unpleasant feeling, Clark couldn't help think, but he knew that the suit wouldn't stand too much more growing.
Another, smaller meteor rushed passed Clark as the growth stopped, and suddenly he realized that in order to save Earth and the areas that would be hit by the meteors he would have to destroy each meteor one by one.
This didn't bode well for Superman's suit.
