More problem-solving
"Oh crap!" Lex exclaimed as his body was lunged across the room. He tried to resist the force of the shockwave, but it came too quickly and without warning. For a moment Lex felt his heart drop. There were time fractures right behind him and he couldn't afford to touch them.
He turned his hands into claws and dug them into the air, grabbing onto space itself! Even if he could not teleport, that did not mean his space affinity was useless. After all, he was still surrounded by space.
Using pure physical strength, Lex resisted a shockwave he suspected was more powerful than the one produced by nuclear bombs. Fortunately, it did not last long.
In truth, this was not enough to hurt him, and if he hadn't been caught unprepared, he would not even have been blown away. But he had been taken by surprise.
Nevertheless, he had saved himself.
