It will most likely be a version of the Arkon Preist, on steroids, with a giant gun, a sword and rockin a Chuck Norris T-Shirt. He will have an Arc Overshield, Void Undershield, & a flaming arkon roundhouse kick. Randal the Vandal up on a balcony in the backaround doing the awoken dance. All six members of your raid fire team will have to snipe him at the same time with Icebreakers to kill him and unlock the 4th secret chest. [spoiler]the chest will only have shards[/spoiler]
