User blog comment:GSFB/Giant Short Faced Bear vs Zombies/@comment-379205-20120706073153

I'm going with the Giant Short Faced Bear. It is capable of taking down Pleistocene megafauna, so it should have little trouble dealing with a group of slow, dumb, unarmed zombies. Also, as per the issue of infection, In some zombie movies and games, one will notice non-zombified animals such as birds, dogs, cats etc. This suggests that these animals may be immune to the zombie virus, and indeed, science backs this up as many diseases effect only an individual species or a small typicallly closely related group of species. And even if the infection does effect it, the bear could take out the entire horde before it succumbs, as seen in the zombie vs vampire fight.
