Sam was losing. He'd come to terms with that a short while ago. Livingness's sheer inability to die was proving to be far more formidable than Sam had predicted, and he was running out of tricks. He started fishing around in his bag for something that might be of use:
A sniper rifle (no good),
A gunblade (somewhat familiar, but still useless),
A Mika CD (how'd that get in there?),
A gold pocket-watch...
Out of sheer desperation, Sam pulled the watch out of his bag and tossed it at Livingness, who just swatted it out of the air. The watch landed on the ground and sprung open, and
Sam remembered...
"Evening." Sam dropped his bag on the ground. "It looks like the plot has, for one reason or another, warranted the requirement of my full powers. If that's the case..." He pointed at Livingness, and a hole opened in his stomach.
"What... the hell...? Why aren't I... healing...?" Livingness coughed and blood came out.
"Because I say so. As a matter of fact, "because I say so" is a pretty good grasp of what my powers are. Anything I decide to make happen, happens. For example:" Livingness caught aflame. "Being an author avatar, anything I write essentially comes into existence. Granted, that makes me undoubtedly the most massively overpowered character in the history of fiction, but sometimes the plot calls for complete overkill." Upon saying this, Sam blinked, and Livingness's body turned into dust. "Begone back to where you came from, you unoriginal character clone."
With all said and done, Sam walked over to the watch. "A stupidly powerful main character would just be horrendously boring; hence the watch. I'd probably better hide it slightly more securely this time..." And thus, Sam sealed his powers and memories (and his glorious bastard personality) in the watch once more, and cast it into the void that marks the edge of the universe. And then he passed out.
