Zoroark is a powerful Pokemon and he got a whole film to convince us of this. His shape shifting abilities won’t be very useful, but he won’t need them in this fight. He can easily overwhelm Bowser in hand to hand combat and he’s lethal from long range as well. Bowser has his Giga Bowser form, but it’s not quick enough to deal with Zoroark. The King of the Koopas is going to have to drop down the blog ranks with this loss. Zoroark wins.
