Aftermath
WWE released a statement on Cesaro's medical condition, stating "Cesaro's teeth were pushed up into his upper jaw by about 3 to 4mm... the next step is most likely removing the teeth and then having some implants made".[23]
Immediately after No Mercy on Raw Talk, John Cena said that Roman Reigns had earned his respect and it was now up to Reigns to continue his momentum forward. He also confirmed that he would be taking some time off. The following night's Raw opened with a segment of Miz TV with Reigns as The Miz's guest where Reigns also said that Cena had earned his respect. Miz said that despite Reigns' victory, he was the one with a championship as he retained his Intercontinental Championship against Jason Jordan. After some arguing, a match between the two was scheduled where Reigns defeated Miz, but after the match, Miz and The Miztourage attacked Reigns. Also that night, Jordan teamed with Matt Hardy in a winning effort over The Miztourage.[24] Dean Ambrose, Seth Rollins, Cesaro, Sheamus, and Braun Strowman were then intertwined in this new rivalry between Reigns and Miz, resulting in The Shield reuniting and taking on the team of The Miz, Strowman, Cesaro, and Sheamus at TLC: Tables, Ladders & Chairs in a 4-on-3 handicap Tables, Ladders, and Chairs match.[25] Kane returned and was added as the fifth member of The Miz's team at TLC.[26]
Enzo Amore had General Manager Kurt Angle sign a no-contact clause, which meant that if any cruiserweight laid their hands on Amore, they could not challenge for the WWE Cruiserweight Championship. Later, Amore's championship celebration was interrupted by the entire cruiserweight division. Amore claimed that he made 205 Live relevant, supported by the fact that they were being featured for the first time as the main event of Raw. Neville said that Amore had made a joke out of the entire division and attacked Amore in spite of the no-contact clause.[24] Immediately after Raw on the WWE Network, Braun Strowman came out and powerslammed Amore and let the entire cruiserweight division each take a shot at him. On 205 Live, Amore said that due to the no-contact clause, none of the cruiserweights could challenge him for the title. Neville also explained that he knew that he risked his title rematch, but did not care and would do it again. Neville then faced Ariya Daivari, who tried to befriend Amore, and Neville won by disqualification after Amore attacked Neville with his crutch and continued to attack him after the match.[27]
Also on Raw Talk, Alexa Bliss said that she had retained the Raw Women's Championship against the entire women's division with the exception of Alicia Fox and Mickie James, who she felt were not worthy to be considered title contenders, especially James, who she said was too old. She also said she looked forward to ending Asuka's undefeated streak. The following night on Raw, James confronted Bliss about her comments on Raw Talk. After Bliss restated her comments, James attacked her and a Raw Women's Championship match between the two was scheduled for TLC.[28] Also in the women's division, Sasha Banks and Bayley teamed up and defeated Emma and Nia Jax.[24] Emma then earned the right to face Asuka at TLC.[25]
Finn Bálor was interviewed backstage. He thanked Bray Wyatt for their No Mercy match and said he would now focus on regaining the Universal Championship. However, later in the show after a match with Goldust, as Bálor stood in the center of the ring celebrating, the lights went out and a child began singing Wyatt's song, "He's Got the Whole World in His Hands".[24] A rematch between Bálor as his newly created demon and Wyatt, embodying "Sister Abigail", was made for TLC.[26] However, Bray was pulled from the match due to a viral infection, and was replaced by SmackDown's AJ Styles.[29]
Following WrestleMania 34 in 2018, brand-exclusive PPVs were discontinued, resulting in WWE reducing the amount of yearly PPVs produced, thus No Mercy was discontinued.[30] After six years, however, No Mercy was reinstated in 2023 for WWE's developmental brand, NXT.[31]
