Scorponok(Beast Wars)VS Fenrir Greyback(Harry Potter)

My next battle has Scorponok, the Predacon second in command from Beast Wars Transformers, taking on his Harry Potter counterpart, Fenrir Greyback, the werewolf wizard! Both are Beast Wars/Harry Potter counterparts, given the fact they are both covered in grey, don't show much in terms of personality throughout their respective series and have a lot of power but not nearly as much intelligence, though Scorponok's got more than Greyback. Both are also predatory animal themed(scorpion and wolf)and appear to be both brutish and quite loyal to their respective leaders(Megatron for Scorponok, Voldemort for Greyback). So, the fight takes place on the roof of a technology center in a forest. No prep or morals, bloodlust is on and the fight is to the death. Scorponok is in robot mode and has his weapons ready to fire, while Greyback has his wand drawn and is ready to pounce like the werewolf he is, as well as cast a spell. Which one wins? The stinging Predacon or the snarling Death Eater?
