Suggested by iKnowledge Oberon is surprisingly powerful. He’s got a large array of abilities including super speed, strength, energy barriers, flight, and much more. He’s a jack of all trades who will keep Wonder Girl quite busy, but ultimately I believe that she surpasses him in the stats that really matter. She is strong enough to simply overpower him and fast enough to make it happen. It won’t be an easy fight, but definitely a very winnable one. Wonder Girl wins.
