Titanfall 2 Edit
He is first seen in the campaign mission The Ark where he is shown destroying the Milita Fleet with his customized Northstar Titan. He nearly kills Jack Cooper by throwing him off the side of a Militia-hijacked IMC ship.
Viper returns to finish Cooper aboard the IMS Malta, but is shot down in the ensuing battle. Just when BT-7274 and Cooper think he's dead, he returns and tackles BT and plummets through the air with the Titan in his grasp. They land aboard the hull of the IMS Draconis and engage in a frantic melee. He rips off BT's arm, but BT destroys his hatch. The exposed Viper is killed by Cooper with small arms fire. There was originally a second Ronin Titan involved in this hectic exchange as seen in the E3 2016 Titanfall 2 Canpaign trailer. Instead of BT tackling Viper after recovering from the fall, he would tackle a Ronin Titan, although the scene changes before anything else was revealed. What became of this Ronin is currently unknown.
