Viper is one of the Apex Predators in Titanfall 2, the 2016 first-person shooter from Respawn Entertainment, and the pilot of the Northstar Titan. He acts as a recurring antagonist in the game's single-player campaign, taunting the player before their confrontations and becoming one of its most memorable boss characters. Clips of his dialogue later spread through gameplay videos, edits and soundboards, where fans reused his lines outside the campaign. He remains popular because his calm confidence makes him instantly recognisable to Titanfall players, even years after release.
