Or, you might consider the mythical swamp creature, Bunyip.
Personally, I prefer the magpie (magpie press) or the hyena (vicious beast, laughs as he does his dirty work)
Ha, ha! Lots of good suggestions. Like the Bunyip.
Then, of course, there’s the most feared Honey Badger, who Bannon took as its mascot.
