(beastius arcanus)
Usually seen among the millions of people running around in Halo 3, the Arcane Beast can be distinguished by the purple stripes and patches it has strewn across its gray body and the large, sword-shaped protrusion on its back. The Arcane Beast, though usually a docile creature, may become aggravated and attack if provoked. (Common provocation methods include, but are not limited to, talking crap about his mother, teabagging and posting things on the internet to intentionally mess with him.)
