That's kind of the idea with the Doxi-series. They're creatures that are virutally impossible to kill just because of how they're physiology is (though, in the games, you'd be able to take them out with special ground moves pretty easily due to all of them having low Sp. Def. stats). I think the mother colony that spawned Doxisite and its siblings would be far more difficult. But, that's why they're all legendary fakes.
But, eh...I haven't made a whole lot of progress in my fics either, and I was thinking about revising them too. But, as for your story, you know what they say, rushed work heralds no fruit; so don't go hurrying to finish chapter two on our account. I mean, it really is high quality work!
