#3 Bo Dallas (WWE SmackDown)
In October 2019, Bo Dallas and Curtis Axel lost a Tag Team Turmoil match against The New Day's Big E and Kofi Kingston at WWE Crown Jewel.
Almost two months later, the former WWE NXT Champion teased a character change when he tweeted that he was on a "life-changing expedition" and fans will witness "a Bo you've never seen" when he returns.
Fast forward seven months, Dallas is yet to reappear on WWE television and his B-Team tag team partner, Curtis Axel, has been released from his contract.
Looking through the WWE SmackDown roster, the one-time WWE RAW Tag Team Champion is someone who would definitely benefit from being given the hacker gimmick, especially now that his four-year association with Axel has come to an end.
From a storyline perspective, it would have made sense for Dallas to target tag teams in the same way that the hacker did. Now, with Axel gone, that storyline would no longer have worked, which might explain why we have not seen the hacker for the last two months.
