#2 Killian Dain

Now, if we're going to choose a Viking partner for Erik and Ivar, surely Killian Dain has to be in the running. The man just looks like a Viking!
With SAnitY's Eric Young being moved over to the red brand, Dain put out a statement saying goodbye to both Young and Alexander Wolfe, their fellow SAnitY member, who's rumored to either be leaving WWE or moving back to NXT.
Look who just shut down all of Tony Khan's critics! More HERE.
Now, Dain has always been a spotlight star in WWE, having appeared at WrestleMania in the Andre The Giant Battle Royal not long after joining NXT - but it seems that his opportunities have been limited as part of SAnitY.
Now that he's by himself, Dain should either make a run at it as a dominant singles star - or unleash his inner Viking and join Ivar and Erik to establish The Viking Experience as one of WWE's most intimidating factions.
