Both WWE and AEW have an immensely talented roster. They are rival promotions, and their feud is getting fiercer by the day.WWE has signed several names from All Elite Wrestling over the years. Names such as Penta, CM Punk, Cody Rhodes, Jade Cargill, Rusev, Stephanie Vaquer, Blake Monroe, and more were once under the Jacksonville-based company's banner. Interestingly, Tony Khan has also signed many former World Wrestling Entertainment names since the promotion's inception.It is unlikely that the above phenomenon will stop anytime soon. The two companies will keep signing each other's stars. However, some AEW stars will probably never join WWE.Here are three such names and why they will never sign with the Stamford-based company.#3. Former AEW World Champion Kenny OmegaFormer World Champion Kenny Omega is the heart and soul of the Tony Khan-led company. He is a modern-day great and has been signed to All Elite Wrestling since 2019. Additionally, he is one of their executive vice presidents. Before AEW was founded, he wrestled in New Japan Pro Wrestling, where he held multiple world titles.It is unlikely that the Cleaner will ever join World Wrestling Entertainment. The Stamford-based company reportedly tried to sign him in 2019 after his NJPW contract expired. However, All Elite Wrestling offered him the opportunity to change wrestling forever. His heart beats for AEW, and it seems like he will stay with them till his retirement.#2. RicochetAEW star Ricochet was signed to WWE from 2018 to 2024. He was moderately successful there, winning the Intercontinental Championship, the United States Championship, and the NXT North American Championship. Unfortunately, he failed to reach his true potential. The Lightskin Kingpin signed with AEW last year, and he has been on a roll.The 37-year-old is currently one of the most over acts in All Elite Wrestling. He is the leader of The Demand, whose members, apart from him, include Bishop Kaun and Toa Liona. He seems to be enjoying his time in the Jacksonville-based company, and it is unlikely that he will ever rejoin WWE.A few months back, he admitted that World Wrestling Entertainment ruined his love and passion for wrestling. However, AEW has restored it.#1. MVPMontel Vontavious Porter (MVP) was once a popular WWE star. He is currently signed to All Elite Wrestling, where he is the manager of The Hurt Syndicate. This faction, apart from him, consists of Bobby Lashley and Shelton Benjamin. Under WWE's banner, they were known as The Hurt Business.It is safe to say that Porter will never return to WWE if Triple H remains at the helm for the foreseeable future. The former United States Champion has admitted that he has zero respect for the Game. In a recent interview with Bet Ideas, he did not hold back."My issues have to do with him as a person and our personal interactions and things that he said and did that caused me to have zero respect for him,” he said.Only time will tell if MVP and Triple H will resolve their disagreements. Unfortunately, this looks unlikely to happen.
