He is later seen in The Ark where he is shown destroying the Milita squadron of Crows with his customized Northstar Titan.
Viper returns later 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 Vanguard Titan in his grasp. They land aboard the hull of the IMS Draconis and engage in a frantic melee. BT tackles Viper, who activates his thrusters and plows BT back into the ground. He rips off BT's left 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 Campaign 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. It is possible this Ronin was simply a stand-in for Viper, as to not spoil the boss fight in a trailer.
Viper has references and influences from Top Gun and Aliens.
His line "Viper's got you in the pipe, 5x5" is similar to a line said by Corporal Colette Ferro in the film Aliens, as the UD-4L Cheyenne dropship enters the atmosphere of the planet LV-426.
His mention of 'Voodoo one' is a reference to Top Gun, as is his callsign. In Top Gun the character Viper is played by Tom Skerrit, who also appeared in Alien.
Viper also makes reference to The Matrix by saying "Dodge this!"
Viper is the only member of the Apex Predators who never shows his face with the exception of Ash - who is a Simulacrum and does not have a face. He also is never called by his real name, unlike the other Apex predators.
His helmet was based on the original female Pulse Blade model during the tech test.
Viper's custom Northstar was the only one of it's kind which could fly for extended periods of time, such as an aircraft would.
