#2 SAnitY

Alexander Wolfe, formerly of the SAnitY faction, has returned to NXT to help boost the budding UK roster, but his fellow SAnitY members, Eric Young and Killian Dain, are rarely used on main roster TV.
The SAnitY group was heavily advertised to make its much-anticipated main roster debut before being called up, but almost immediately after they debuted on the main roster, they vanished from TV and were quietly broken up.

It's possible the SAnitY group too closely mirrored the Wyatt Family during their heyday in NXT, but with The Wyatt Family disbanding, there is room once again in WWE for a stable such as SAnitY.
Should all the members of the group, sans Nikki Cross, who is currently in a program with Alexa Bliss and Bayley, return to NXT, the faction could re-establish purpose in WWE and define what exactly makes them such a unique and edgy group.
