Interesting theory...mmmmm...you got me thinking....
I defo think Dumbledore trusted Snape for a reason but I don't know if he trusted him of being on their side or to use him for something...

Well, snape being fawkes, i wouldnt say its not possible, but it doesn't really make sence as to where the story is going. to mee it doesn't seem something that rowling would do. and im not entirely sure if snape is good or not. think hes bad first off because he made the unbreakable vow with dracos mother.

i love snape by the way

but snape can't be fawkes because what about alll those times harry was in dumbledoore's office and fawkes was there snape couldn't have gotten past him without harry seeing him . And what about the times when snape and fawkes were in the office together. besides i hate snape and he is a good for nothing COWARD.

If you can both tell me where Snape and Fawkes were in the office together in the book, let me know. Becuase I see no times when they were together.

And also, the movies don't count.

Wow.I don't know what to think now. It makes me wonder.
No, wait.
Fawkes got into the Chamber of Secrets, so if Snape was Fawkes he must of known where the Chamber of Secrets was.
So if he was oh so good, why didn't he tell DD where the chamber was?
Oh!
What if he was bad but he was Fawkes?

You sir are not looking in the right direction i am sorry to say. Yes Snape may have saved Harry and killed Dumbledore, but i am fairly certain that he is not an Animagus and definitely not Fawkes.

that is a really good theroy but i dont believe in it

No way Snape can't be.....oh well....i hate him

Good Theory..but I'm not sure if I can believe it

i dont think this would be true because snape has been in dumbledores office when fawkes was i there to im sure of it!

I most say that's sounds good but, I don't believe it the only occurs to me that the only way Snape has saved Harry's life through out the books because he didn't want to be expose and he was remiend in Howgarts as a spy, he truly respect the Dark Lord and he wouldn't touch Harry under any circunstances if wasn't order by the Dark Lord.

There is no way snape could be Fawkes is impossible!!!!!!!!! that's all I have to say

Nope, I've checked the whole series. They are never seen together.

Wow! What a theory. I'm not saying that it's bad, or even that it's impossible, but it is extremely unlikely. Even though no evidence exists that dismisses this theory, one should always look for the most obvious answer, because the obvious answer is usually right. It's probably a sheer coincidence that Snape and Fawkes were never in a scene together. Also, there is the matter of complications regarding Fawkes' immortality. This would mean, and correct me if I'm wrong, that Snape could turn into an immortal creature. Therefore, he could be immortal if he really wanted to. Others have commented on the age complications, too; which certainly weaken the integrity of this theory. One more point is that Fawkes is usually seen in Dumbledore's office. He may not always be there, but Snape would have to be missing very often in order to be Fawkes. All of this aside, though, this is quite an amazing theory. I applaud you just for coming up with it; I probably never could have. So while I'm not exactly convinced, I am impressed.

Hrmmm... I did think at some point Snape was an Animagus, but I never considered Fawkes... that is, indeed, a fascinating theory! I dunno if I believe it; a lot of things don't make sense, but some other things do. o_O I think it's far-fetched, but then again JK does have that special talent of pulling off plot twists. X3

Hold up, now that I think about it... during some interview or another, didn't JK say that Snape's Patronus would reveal too much? Do you think that, if your theory were true, that would have something to do with it? I dunno, just throwing ideas around.

Great theory! <3

i think its really interesting and i think your onto something.. personnally i think that Snape is good because Dumbledore the greatest wizard of all time would trust him unless he was very confident he was good or maybe he knew he would have to sacrifice himself in orrder to make Snape realize something. I think in the end he will somehow save Harry by sacrificing himself because James saved his life also to pay back his sort of dept for killing Dumbledore.. I dont know but interesting theory!

You think Snape is an Animagus then? We know that there are at least 6 other registered Animagus and who knows how many are un-registered (Sirius, James, Peter & Rita are all unregistered).

But I thought the choice of animal is not up to the user, but instead reflects something of one's inner nature. The same is true of the form of one's Patronus.

So if we assume that a wizard's Animagus form and Patronus will be the same, wouldn't DD change into Fawkes and not Snape?

This is very interesting and entirely speculative. It will great to find out what Snape's Patronus be (maybe book 7 will let us know). And no Animagi have yet conjured Patronuses any of the books. I wonder it that is for a special reason?

well,I must admit that Snape is the real mystery,but we all don't know the true fact,I think I'd better wait for the next book.

I don't Snape can possibly be Fawkes. LV has a wand powered by one of his feathers. He got this wand long before Snape came on the scene.

Good theory! But I really don't think Snape would turn into a phoenix. He might be a animagus, but I don't think he's Fawkes... Here are some reasons,

: I really really really don't think Snape would cry and heal Harry. Crying+Snape just don't mix..
: Snape doesn't like Harry. I feel that Snape has not a scrap of good feeling towards Harry. He doesn't hate him enough to kill him.. but the hatred between the Snapes and Potters will go on.. and on..
: Fawkes is sweet. Snape isn't. (Not a real reason but anyways/.)
: I believe that Snape saves Harry, only because he is not a murderer(besides when he killed Dumbly, but that might be on Dumbly's orders so.) so he wouldn't just stand there staring at Harry as someone was about to use the Avada Kedavra on Harry.. Nope.

So.. This theory is very good, but more creative. ^^; But I really don't think this is right. So.. ^^;; But if this is right............................ OMGOSH SNAPE CRIED!!!! Lol.. Anyways, this is my opinion.. So don't take any offense if you take any.. Wait.. What? Confusing myself.. Ugh.

Thanks all for the feedback. Every day I have to reconvince myself of this theory, there is so much against it, but I think it would be awesome as well.

Thanks for the feedback!

AHHHHH!!!! YOU CAN'T APPARATE INSIDE THE HOGWARTS GROUNDS!!!!!!!!!

No doh. He ran outside grounds.

That's what he did in the book and that's what I was talking about.

Good theory...but I don't believe it. Why? well it's like this: if Snape was really Fawkes why wasn't there a reaction when Harry attacked him (strong stunner in PoA) after all Fawkes is the source of Harry's phoenix feather. I think the out come would be like Priori Incantatem. Please feel free to debate this.

Yeah its a good theory .it seems u have worked hard but its a bit difficult to beleive it.I think Snape killed Dumbliedoor on his order bec i think DD wanted to save Malfoy's and Snape's life as he was very generous .Or its possible that Snape killed DD to save his own life as he was under unbreakable vow .Its difficult to decide on what side Snape is as J.K rowling has not clearly described his faith.
