Zer0

Zer0 is the playable Assassin class character in Borderlands 2.

Zer0 was revealed on February 21, 2012, in the Borderlands 2 Launch Date Trailer. His nickname comes from the "0" hologram sometimes displayed over his faceplate when he dispatches a target. Other emotes and text appear on his faceplate - and on enemies, using the B0re skill - during different actions. Most of Zer0's phrases are spoken in haiku.

Background
Zer0 is an assassin for hire. According to his wanted poster and his personal ECHO recordings, he performs both political assassinations and common hits. Following a particularly unsatisfying assassination where the target fails to fight back, despite being encouraged by Zer0 to do so, the assassin starts to look for a more challenging environment. He travels to Pandora after hearing of the Vault from a bartender, deeming the hunt as worthy of his skills.

As his face and body are completely covered by his suit, a certain amount of mystery surrounds Zer0's true appearance. In an ECHO recording, Angel remarks that she's not even sure if Zer0 is human; both in-game and promotional material show that he has only four fingers on each hand. His origins and real name are also unknown, giving the character the full mysterious background. It was confirmed in a Gameinformer article that he is actually a robot of some kind [Citation Needed].

Skills
Action Skill: Decepti0n

"Decepti0n" grants Zer0 the ability to deploy a holographic decoy of himself and enter an invisible "stealth mode." While cloaked, he can maneuver about the battlefield dealing amplified damage on his next attack. The longer Zer0 stays cloaked, the more damage he can inflict to enemies; however, the shorter Zer0 stays cloaked, the sooner he is able to use the skill again. Zer0 does not enter a separate dimension like Lilith when she Phasewalks, and can still take damage from all sources while cloaked.

Decepti0n has a base cooldown of 15 seconds and gives up to +650% Melee Damage or +200% Gun Damage and +250% Gun Critical Hit Damage.

Trivia

 * Gearbox concept designer, Scott Kester, credits Zer0's inspiration to "loner characters" like Snake Eyes from G.I. Joe and Gray Fox from the Metal Gear video game series.
 * Most of Zer0's dialogue is spoken in haiku, which is noted once by Handsome Jack in an ECHO recorder.
 * Zer0's version of the "Slayer of Terramorphous" Class Mod was once bugged, providing a bonus to one of another playable character's, Salvador, the Gunzerker class, skills. It has since been fixed in a patch.
 * When using the Handsome Jack Voice Modulator, Zer0 will become far less talkative. Many of his lines are replaced with lines that are cut short as though Zer0 was about to say something, heard his own voice, and decided against it.
 * Zer0 stands at 6'4"/1.93 metres, which stands him as the tallest playable character in Borderlands 2.
 * Zer0's wanted poster has the code 000 000 000 HSP, the joke being that the entire numerical code is just 0s, as part of a running gag Zer0 has with the respective number, along with other jokes in other areas.
 * Sometimes a Glitch can occur where (if) Zer0 leaves a multiplayer game while making a Faceplate Projection, the image will still float there, until shrinking away as if Zer0 was still there.
 * The line, "This is the story / All about how my life got / Flipped, turned upside-down." from killing an enemy by running them over is a reference to the Fresh Prince of Bel-Air's intro song.
 * Zer0's line when entering Decepti0n, "How hilarious / You just set off my trap card / Your death approaches." is a reference to Yu-Gi-Oh, where a trap card would be used in response to another player's actions.
