#1 Putting the Universal Title on The Fiend

WWE introduced fans to The Fiend in 2019 and while the character has absolutely set the world on fire since then, it didn't start out all that great. Now that's not to say that the vignettes weren't cool to watch or that his surprise attacks weren't scary to witness, but his Hell in a Cell match with Seth Rollins almost killed all that momentum.
Of course, a lot of that had to do with how badly the WWE Universe wanted The Fiend to win the Universal Title and the fact that they ended the match by referee stoppage, but it was clear that the fans weren't happy. Interestingly enough, WWE quickly reworked on their decision and had The Fiend win the belt the very next month.

Maybe it was because of the backlash from the fans, or maybe it was WWE's plan all along, but the company finally put the belt on The Fiend was a firm sign that the company was indeed listening. It also showed that WWE was willing to do whatever is needed to make sure that fans are happy.
