[Walrus]

For wrestling and other grappling effects one should buy Lifting ST, not Striking ST, IIRC.

Also, his Night Vision is more a feature (normal vision at -5, not at 0), as in Fantasy.

I'd say he has some sort of Social Stigma: Savage or even Monster. It's Frodo's Xenophilia and Gandalf's knowledge to save him from being shot at sight.

And he has some Weakness or, more likely, Susceptibility to "Strike Evil" effects, like elven rope or bright sun. Or Delusion that he has one. Or this may be a feature balacned with that Resistance. Something like "counts as Evil creature for supernatural effects".
