BayleyBayley’s actions during the No Disqualification, No Countout, Last Chance Match between Lyra Valkyria and Becky Lynch for the Women’s Intercontinental Championship at this year's SummerSlam suggest a potential heel turn. She interfered but accidentally hit the challenger Valkyria, costing her the title. The frustration due to her miscalculation and previous misfortunes inside the ring could lead to her becoming a villain again.Further, her feeling of being overlooked in WWE’s women’s division could also trigger the aforementioned character shift.#3. Could Asuka turn heel following SummerSlam?Asuka’s loss to Jade Cargill in the Queen of the Ring Tournament final at this year’s Night of Champions could be one of the reasons for the former’s potential heel turn.The former champion has been absent from major title contention, which could also fuel frustration. She and Kairi Sane may have re-formed The Kabuki Warriors at Evolution, but a heel turn could see her betray Sane or target other female superstars to get even. She could also sway Kairi into turning and put WWE’s women’s roster on notice.#2. Randy OrtonRandy Orton has faced significant failures in major matches that he has competed in, which include his losses to John Cena for the Undisputed WWE Championship at Backlash, Cody Rhodes at Night of Champions, and Drew McIntyre and Logan Paul at SummerSlam, with singer-songwriter Jelly Roll as his tag partner.There were already not-so-subtle hints of him turning heel during those matches. A case in point was when he removed the protective padding of the top turnbuckle during his match against Rhodes at Night of Champions.Another thing worth noting is McIntyre’s taunts about his fading legacy, which could push him to unleash The Apex Predator in him once again.#1.

Her near-pin using her Jaded finisher, only for Stratton’s foot to reach the ropes, could leave The Storm feeling bitter. Frustration over being outshone by Tiffany could push her to adopt a more aggressive persona.A heel Cargill could unleash her powerhouse style even more and rain it down on fan-favorite babyfaces, further solidifying her as one of WWE’s top female superstars.
