Lycanthropes and Possession

[Revengeance]

"All lycanthropes have three forms—a humanoid form, an animal form, and a hybrid form. Equipment does not meld with the new form between humanoid and hybrid form, but does between those forms and animal form. A natural lycanthrope can shift to any of its three alternate forms as a move-equivalent action. An afflicted lycanthrope can assume animal or hybrid form as a full-round action by making a DC 15 Constitution check, or humanoid form as a full-round action by making a DC 20 Constitution check...

"A natural lycanthrope’s bite attack in animal or hybrid form infects a humanoid target with lycanthropy."

Suppose that a wizard contracts lycanthropy. He does not cure it, and becomes capable of changing shape at will. He then successfully casts a possession effect (Magic Jar, Parasitic Soul, etc) on a creature (let's say a dragon).

Can the dragon body change form to a humanoid? To an animal? Can it change back, so that there are now 4 forms available (for the duration of the Magic Jar)? Does the wizard lose the lycanthrope template's effects while the possession is active?

"You keep your Intelligence, Wisdom, Charisma, level, class, base attack bonus, base save bonuses, alignment, and mental abilities. The body retains its Strength, Dexterity, Constitution, hit points, natural abilities, and automatic abilities."

I don't think that ability to change shape is transfered when you possess another body.

[Revengeance]

That's the most logical, but it's supernatural - and I was under the impression supernatural abilities move along with possession.

It's a magical disease of the body - it will not follow you when you possess another.

The body retains its Strength, Dexterity, Constitution, hit points, natural abilities, and automatic abilities. A body with extra limbs doesn’t allow you to make more attacks (or more advantageous two-weapon attacks) than normal. You can’t activate the body’s extraordinary or supernatural abilities, nor can you cast any of its spells or spell-like abilities.

The Spell says that the host body retains its own physical based Abilities and it later confirms that Supernatural Abilities can be bodily based. Additionally, the possessing Creature carries over its Class - this is how you see possessors utilize (some of) their own Spell-Like and Supernatural Abilities. From this I would concur with others here that you cannot transform into Werewolf forms during possession; even if your Lycanthropy is caused by a Curse Effect it still manifests as a bodily affliction - the body gains the Shapechanger Subtype, working alongside Change Shape (Su) for taking Werewolf form. Also note that Lycanthropy can be passed onto descendants as natural Lycanthropy or as the Skinwalker Race. If argued that the Curse Targets "you" the soul/mind I would say that it still remains with the original body targeted - if I Cast a Polymorph Spell on my original body and then Cast Possession to take control of another's body, I would not expect the Polymorph Spell to "follow" me.

EDIT : It might cause interaction problems when possessing a non-Humanoid - would the possession remove the Curse as you were no longer (bodily) a valid Humanoid Target? Would it count as having it for purposes of your soul/mind but simultaneously not for your (hijacked) body?
