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.



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.[1]

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 digits on each hand. His origins and real name are also unknown, leaving the character shrouded in mystery.

As revealed in the "Ask Dr. Tannis" Section of the Pandoran Gazette, included as a scrap of paper in the Diamond Plate Loot chest, Zer0 is not his true name. The remaining piece of scrap containing the name and gender of Zer0 were not included, but the part that does remain suggests that Patricia Tannis is aware of Zer0's origins.


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.
