Always have an editor. Grammar isn't really your strong suit, and it's probably the most important aspect of writing. Your character has no posessions or family, except the family that took his posessions... what? Why doesn't he just live with them? Go into that a bit more in a prologue, or ignore it entirely. If it's not relevant at the time, don't prattle on about the past.
If this is supposed to take place in the real world, it's very unlikely that Jack wouldn't know what Pokémon are, unless they died out long ago, in which case Smith probably would not have heard of it.
What kind of first name is Smith, anyway? Your names all sound like you thought about them for 12 seconds. Jack is a name that should only go to badass characters, and your Jack is hardly badass.
The "machine teleports-you-to-TV" makes no sense and is imposssible.
Develop things a bit more. How does NotJack know he has amnesia?
At least you didn't tangle Tracey and Misty in the party, but why are they there in the first place? Don't bastardize existing characters, make your own. It's more interesting.
‘Prepare for trouble…’ (You know)
Never do this. For that matter, I really hope TR don't attack in every chapter.
Planet Town isn't really a good name for a town, and why is Professor Oak there?
Also, you have bigger issues to worry about, but it was far too short.
