#6 The Riott Squad

Much like the aforementioned Absolution, The Riott Squad made quite the dominant start to their main roster WWE careers, paralleling their Raw counterparts on the blue brand when they assaulted the SmackDown women's roster - beginning with Naomi and Becky Lynch backstage.
On the same show, the trio interrupted a SmackDown Women's title match between the champion, Charlotte Flair, and the challenger, Natalya - attacking both competitors.
The leader of the faction, Ruby Riott, has had the most main roster success, pinning Charlotte Flair and having a very impressive run in a Gauntlet Match on Raw recently, and the trio are still wreaking havoc on the brand.
While Ruby Riott shows the most promise here, and should arguably have been in line for a title run had Rousey not joined WWE, The Riott Squad holding all the gold may now be a pipe dream. Of course, The Riott Squad could always use the Freebird Rule.
