Seth Rollins is on the verge of turning heel soonOnce upon a time, Seth Rollins defeated Brock Lesnar to become the Universal Champion and was the most beloved babyface in the whole WWE roster. And then, whether it was because of a disconnect between him and the WWE Universe, or just because of poor creative, the WWE Universe began to turn on Seth Rollins.Currently, he is involved in a storyline with The AoP where the brutes choose to leave him be but unleash their wrath and fury upon Kevin Owens. It is amply clear that we're headed for a huge heel turn from the 'Beast Slayer' very soon.But then, Seth Rollins is also arguably the best pro wrestler in the whole wide world and there will be a huge gulf with regard to who can carry the brand on his shoulders if the man chooses to embrace his dark side very soon.I will try and answer the question by naming 5 potential contenders.#5 Rey MysterioLegendary moments!! https://t.co/a1YwgvJ1zn— ♛Rey Mysterio❔ (@reymysterio) December 1, 2019Let me preface this article by saying that I'm not including Becky Lynch in this list and before you come at me with pitchforks, it's because she will effectively not be filling the Seth Rollins 'top babyface' void. She is already at the top of the food chain and is featured in the most prominent storylines for the women, so the question of replacing Seth Rollins does not even arise.But on the other hand, Rey Mysterio has a world of goodwill. He is someone who should have been featured more prominently than he has since his return to the company. And he can work with younger heels like Andrade and Drew McIntyre, and in turn, elevate them greatly.Mysterio already had crowd support heading into his match against Brock Lesnar at WWE Survivor Series. He can certainly use the momentum to become the face of RAW when Seth Rollins finally turns heel.
