Hmm.... for one, I'd say that this story's plot sounds suspiciously like Glajummy's already written "Shining Nightmare" at this point. Shiny Pokemon with superior powers are created by the bad guys to take over the world. I mean, even the whole thing about the tackling making a hole in the wall occurs in that fic (which was written before this one if I am not mistaken). You'll have to be very careful to avoid ripping anything else off from it, intentionally or no.
As Hanako-sama said, you need much better grammar (on which there is a lovely stickied thread here). I mean, you've still got wonky sentences, like this one for instance.
"Well..., it's easier if i show you"Nick said while reaching into his coat pocket and taking out a poke ball. He pressed the white button on it and out came a beam of red light that materialized into a feebas, but this feebas was different it was purple and looked much stronger than any other Giovanni had seen before. "tackle" commanded the scientist while pointing at the wall. After a splashing head start, the feebas threw himself at the wall a few momments later there was a huge hole in the wall were the feebas had hit. "you see?" nick asked while recalling his feebas into his poke-ball.
Aside from the run-on sentences, you've got quite a few unfixed errors which I took the time to highlight (spelling and capitalization mostly). Your fic needs a bit more revision, I'd say.
