fighting us twice to a draw (both times he really didn't 'win' as more simply walk away from boredom in the first fight and the second third parties showed up and evened the stakes, again making him withdraw out of spite), and only 'defeated' us by using some random plot coupon for instant victory. But he lost points by scaling up with Shinryu, which opened him up to a fatal weakness - we're the 'Eikon Slayer' after all, so he basically lowered himself in a way at the end, Shinryu's own immense power notwithstanding.
