Zer0

Zer0 is the playable Assassin class character in Borderlands 2.

He was revealed on February 21, 2012, in the Borderlands 2 Launch Date Trailer. His (gender presumed) origins, his nature, and even his real name are as of yet unknown. He is simply called "Zer0" because when he dispatches an enemy he displays a "0" on his faceplate. Other emotes, such as a "smiley face," pop up on his faceplate during different actions.

Known Skills
Action Skill: Deception

Zer0's Skill, Deception, grants him the ability to deploy a holographic decoy of himself and enter an invisible "stealth mode." While cloaked Zer0 can maneuver about the battlefield dealing critical strikes to enemies. Special vision while cloaked shows enemies' critical hit locations highlighted in blue. The longer Zer0 stays cloaked the more damage he can inflict to enemies. Zer0 does not enter a separate dimension, like Lilith when she Phasewalks, and can still take damage from grenades and other forms of splash damage while cloaked.

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

Undetermined skills


 * Killer
 * ??? - Kill Skill. Resets Zer0's Action Skill cooldown?
 * Many Mustfall? - Summons holographic clones to distract enemies?

Melee Weapon
Zer0's basic melee attack uses his sword. The sword is not an equippable item but its effectiveness in combat can be enhanced. The sword's hilt "exists" but the blade digistructs when the hilt is pulled from its sheathe.

Trivia

 * Gearbox concept designer, Scott Kester, credits Zer0's inspiration to "loner characters" like Snake Eyes from the G.I. Joe animated television series and Grey Fox from the Metal Gear video game series.
