Making A Horrifying Hybrid?

I've been working on a supernatural adventure/romance for a number of years. In the story the vampires and werewolves are portrayed in a mostly straightforward—the vampires are graceful sun-sensitive and diabolical Beautiful Elite while werewolves are have the whole "rugged but sexy men and women with explosive tempers" thing going on.

However there is a villain who, in a serious case of From Nobody to Nightmare, goes from a vampire's human slave/captive to being the first and only vampire werewolf hybrid in the world. They are regarded as an "abomination", and "true monster". What I want to know is this:

The hybrid can shape-shift similar to a pure-blood werewolf, but this second form is hideous and distorted. What sort of deformities or "quirks" would make this "werewolf" body absolutely monstrous and give a clear indication that it is an aberration? I had a similar question about the "human form" of the hybrid, but I'm starting to come up with ideas, but remain stuck on the werewolf aspect of it.

I imagine it would inherit a lot of unsettling vampiric traits. Maybe it could have a lamprey wouth, or lots of bone spikes jutting out of matted, bloody fur. Heck, the fur itself could have blistered bald patches like an irradiated wolfman.

Bat wings; either vestigial or lopsided.

Maybe make it hairless and bat-snouted? Or maybe more behavioural, like this aberrant werewolf form would kill its prey viciously, and then not eat it; werewolves hate that he's wasteful, vampires hate that he's sloppy. Or maybe there's something slow-moving and dolorous about it. Werewolves are creeped out that he's apparently passionless, vampires hate that he's ugly.

Have the werewolf form look dead. It's the rotting corpse of a wolf, rather than the wolf itself.

Two suggestions going off what people are saying. I'd actually love to know what you end up coming up with!

1.) Make it a were-bat. 2.) Have him be something of a mutated in-between thing—not quite a human but not quite a dog either. Werewolves technically are this, but that's not what I mean: imagine someone literally smashed a human and a dog together. He could be sort of the wolf version of the Jeff Goldblum fly monster...this tangled but threatening mess (sort of corpse-looking too, as the other troper mentioned).

Uh...bump? I'd just like a little more ideas or suggestions on this, please.

When it doubt, make it a cannibal.

Oh, and here's a thought. A vampire with wolf like trait.

A vampire...who forms a pack!

I apologize for the second bump, but I really would like some more feedback on this, if it isn't too much trouble. I have the the "human form's" appearance down and the exploits of the beast form mapped out but I just can't get that second shape's appearance right in my mind.

Turn it into wolf version of Uncanny Valley. Nothing big - maybe its eyes look dead, or it moves a bit stiffly, or its legs are more slender, or it just flat out doesn't mesh well with a pack.

IMO, the unfortunate problem of creating horrifying things is that you can't really terrify everyone with appearances. So perhaps rather than have it appear odd, have it act odd - like mentioned above, werewolf that doesn't eat its prey, or maybe vampire that kills its victims in very brutal or animalistic manner. Have him stalk the shadows, get uncomfortably close to people, that kind of things that just creep people out.

Or maybe research how real wolves act, have your hybrid act in other way and describe how other werewolves are creeped out by this.

Genius.
