(Kidding.)
I do have a question, though. Is this missionable? It's a crossover between Forgotten Realms and Lord of the Rings.
On one hand, its SPaG is pretty much OK, and so far (I've read the first two chapters) the heroine does not look like a Sue. On the other hand, it copies LotR almost word for word (Rose Potter springs to mind), the main heroine is rather OOC, and the fact that she was inserted into the story does not change it at all save in some minor ways, a la In Spite of a Nail.

There's options other than killing a fic. Maybe some of them would make sense.

PPC doesn't kill fics unless they're irredeemable, and even then they might rescue bit characters. This is because every fic has the potential to strengthen a continuum and every Author has the potential to become a goodfic author.

Option one: Send the author to an OFU. Is there one for MLP? If so, you could invite the author to submit a fanbrat. In the Real World, you simply teach him what you know about writing, and he gets better at it; problem solved.

Option two: Send in Intel. If there's not too much of a problem, they watch and wait until they know for sure. Allows for an in-character review without killing the fic.

Option three: Fixing glitches. When a fic isn't bad enough to be killed, but there is an error in it that could cause problems, a team of agents may be sent in to fix it. This works for fics which, other than a small number of mistakes, are good stories that will strengthen the continuum.

Option four: A non-lethal mission due to a clerical error that sent a moderately good fic to the Action Departments. Agents could go in expecting to kill a Sue, but realize the Sue has potential or the grammar is fixable. Maybe the more homicidal partner gets annoyed s/he doesn't get to kill anything, or maybe they both get annoyed with the Flowers or with their Console. In either case, they might get to explore the fic without touching it, or perhaps fix small mistakes as with the "Glitches" option.

I know, I'm a newbie and probably not as qualified as most to say this, but the fic doesn't seem as bad as the ones we typically do missions on. There are a few punctuation and organization problems, but not much that's really notably charge-worthy aside from Kirby suddenly learning to speak understandably(and I've never played Return to Dream Land; he might be able to talk there regardless).

Like Phobos said, a badfic that Agents are sent into would contain bad characterization, a strange or ridiculous plot that it thinks makes perfect sense, often terrible spelling, etcetera, and is deemed "bad" by a group of people that serve as impartial analyzers.

Antithesis of Harmony is more "first draft" than "badfic". Almost everyone is acceptably in character, and the ones that aren't either are only slightly deviated from their regular persona or their OOC moment has precedent in one of the two canons. The spelling is fine, aside from a few typos, and the grammar is only distorted due to the aforementioned organization problems.

I'm not sure what he "desperately needs help" with. If it's problems with working up the motivation to write, I don't know what a sporking could do for him, aside from making him reluctant to write again, and that's not what we'd want at all.

It seems to me that what you want is not a mission. If the writing is not that bad, and your friend really just needs a self-esteem boost, then a mission is far from an ideal way to achieve your goals.

A mission takes a piece of bad writing and puts it through the wringer. It makes jokes at the expense of the bad spelling, punctuation, and grammar. It satirizes the bad characterizations. It usually involves totally dismantling the story to return the canon to normal. It focuses, almost exclusively, on what was done wrong. And that really is not what you need here.

I just want to make sure you know what you are asking. These terms have very specific meanings around here.
