Actually, it's more like Jyggalag has multiple personality disorder. Sheogorath and Jyggalag share the same body (As shown in Shivering Isles. At one point Sheogorath raises into the air and morphs into Jyggalag) until the Hero defeats Jyggalag in the Greymarch, effectively "removing" the multiple personality disorder. Then the Hero becomes the new Madgod. Either way, Daedra have no true form (Mehrunes' true form would be more like his most powerful form.), so anything about a form is generally rendered invalid.
