I liked how you played with the changing fic formats and had them affect Florestan. That was definitely a unique problem to this fic, and it's good that you focused on that. (It might have been fun to have both the agents get sick from it, to underscore how bad the shifting was.)

But speaking of Florestan's reactions, you have him getting angry frequently here, and a lot of the time I don't really understand why. He keeps reacting to the fic quotes we see by calling them stupid, but it's better to show the audience why Florestan finds them stupid, rather than just labeling them as such. This is especially important in a chaotic crossover like this one, where it's pretty much guaranteed your audience won't understand at least one of the continua involved. You did do this well with Viper, explaining how her fic-given backstory completely contradicted her canon one. But something like Tails being an orphan with no family is something not everyone would know.

Also, you've made a mini-Darkside in your charge list: it's Organization XIII, not Organization 13. (Another fun thing you could have touched on: only Nobodies are part of the Organization. Is the replacement!Tails in this fic a Nobody?)

...Owch, talk about your bad fics. At least your agents took care of this one. (Seriously, how do all those different series go together?!)

First off, I really like how you handled the shifts from prose to script and back. Good job on that.

I have to say, however, that I did not really like the mission. There were several problems:

1) Almost everyone is a character replacement. While I agree that Tails definitely was a replacement, there was no evidence that Sephiroth was, except for the CAD saying it. Viper's altered backstory was also not enough to make her a replacement, in my opinion. I don't know about Shifu, as I am not familiar with the character, but I would guess that he was also not a replacement, just very out of character.

A replacement has to have more than just superficial changes. Like Tails. He had uncanonical powers, was out of his world, answered to his given name (which, I seem to recall, he hates) rather than his preferred nickname, and bore no resemblance to his original characterization. He was a replacement.

1.5) Why kill three replacements, but neuralyze the fourth? Whatever the method, keep it consistent.

2) Some of your grammar is off. For instance "When the shift ended, Florestan found himself leaning against a nearby house as he shook his head." That is a very awkward sentence. We don't need to be told that the house is nearby; it would have to be if he is leaning on it. How is it that he found himself doing these things? Did he not know that he had leaned against a house? It would be better written as "When the shift ended, Florestan leaned against a house and shook his head."

This is not the only example, it is just the one that came most readily to mind.

2.5) Never use the term "soon after" ever again, please. You are trying too hard to tell us the order of events, when the narrative already does that for you. "He opened the bottle and took a swig of the Bleepto-dismal soon after." That is a clear example. The order of events is clear from the sentence, making the "soon after" redundant.

Also, you used "soon after" eight times in thirteen pages. That includes where you used it twice in one sentence. "Both agents closed their eyes soon after, with Florestan activating the neuralyzer soon after."

3) The assassination was anti-climactic. It just kind of happened. Tails stood there while they read the charges, Eusabius pulls out the pikestaff, and then Tails is dead. Why didn't he fight back? He has shown that he is not afraid to kill people without a second thought. I think that this was a major missed opportunity.

4) That's it for my specific notes on problems.

Like I said earlier, the way you handled the shifts was excellent. I would also add that you did a good job of explaining why Viper's new backstory was so wrong. I don't know anything about Kung Fu Panda, so I had no way of knowing that they had completely reversed her backstory. I didn't feel lost at all in regards to what was happening in that continuum.

How can someone even manage do that? As usual, the mission was a highly entertaining read :D Can't wait to read more on about your agents.

That was painful just to read snippets of. I'd hate to actually be there, living through all of that...shifting.

Have a chocolate cake, as congratulations for killing this abomination of formatting. It was spawned by Weaselcake himself, so it's naturally delicious.

Now, you say there's an even worse fic? Do you mean one with worse formatting or just worse in general?

Good job getting rid of that fic. I really like Kung Fu Panda and it was awful to see what it was doing to the story.
Also a good mission. Eusabius might want to look into getting one of those advanced CADs that can block tense shifts.

I enjoyed reading this. Good job!

Although, what about Axel? Was he actually in the fic? Or was he not because he was never shown?
