I could go for an Alien wearing a torn up Nostromo space suit, one with kill marks scratched into its dome, a "Jeri" model with all sorts of wires hanging out, one wearing a boater hat, one wearing a teeshirt with a human baby bursting through, one with the smart ass nose art sprayed onto its dome, a zombie version with the hole in the back of its head from Hicks shotgun... all sorts of goofy stuff but a dog collar?
Its not even clever.
