Vampire or Hybrid?

If you'd read my previous posts for the last three months, I've been playing a werewolf character. I'm just been told now that I'm not just a werewolf. I'm either all vampire or a mix of the two. The story is that in the same month I got bit by a werewolf and a vampire(just my luck). Now I got bit by the werewolf first and this was before my first full moon. Now me and my friend Kenny have been looking some stuff up and we've realized that lycanthropy is a disease and that vampires are immune to disease. Now because I got bit by the wolf first and I'm not dead am I all vampire from that standard or am I a hybrid of both? Either way I'm good, I honestly like vampires better.

I'd say, according the RAW, the following occurred:
1 - You were bitten by a werewolf, inflicted with lycanthropy.
2 - You became a lycanthrope (werewolf).
3 - You were bitten by a vampire, inflicted with vampirism, gained immunity to diseases, cleansing current afflictions (of which lycanthropy is one).
4 - You became a vampire.

So, in short: you are not a hybrid, as no such thing exists (unless you're playing an Underworld RPG). You are a vampire.

Now, were I DM, I'd probably rule both as magical diseases, each granting immunity to the other. So, whichever you become first is what you're stuck with, unless through some sort of ritual you are cleansed of the affliction.

First of all, vampirism is not speareded by bites as such. It is contracted by being killed by vampire's blood drain or energy drain. Just being bitten by vampire does not make one a vampire unless it drained you dry.

As to the question itself - while lycanthropy is spread like a disease I would say that immunity to supernatural diseases would remove it only if gained within the first three days of being bitten, afterwards it is maintained as a potent curse. There are myths about people that were werewolves while alive and later rose as vampires after death (there are also myths of people who were sinners alive and rose as werewolvs after death but it's another story - time to brew some kind of undead werewolf).

Vampirism is not a disease model in PF; it's a negative material energy thing.

Whereas lycanthropy is a disease model, but laced through with curses and magic.

Personally, I wouldn't want to play either of 'em, myself -- too many well-known vulnerabilities for not enough power return.

The REAL power is the shade template (Forgotten Realms).

Lycanthropy is a template that may be applied to a humanoid creature.
Undead are no longer humanoids, if they ever were.
Vampire is a template that makes a creature undead.

I might think that invalid templates 'fall off'.

The DM has to decide if the Lycanthropy is a disease or a curse that acts like a disease.

If it is a disease, you are no longer a werewolf. Though, you could decide to keep some bestial qualities for RP purposes.

If it is a curse, you would probably still be a werewolf. Though, you could rule that an undead can not sustain the curse.

One thing to note, some of the Lycanthrope bonuses do not stack with the vampire bonuses. For example, as a vampire, your strength is probably high enough that changing forms would only grant you the +2 to strength and your DR is better than what you get from Lycanthropy. Add in the penalty to charisma reducing your HP and you might actually be weaker as a hybrid. If you want to be a hybrid, I would suggest getting your DM to agree to drop the Lycanthrope template but be able to shift to hybrid form for no mechanical benefit. That way you get the flavor without penalizing your character for a +1 CR adjustment.

I think that whatever you're trying to become is something completely different from a werewolf or a vampire.
