E4-XX

"*feminine-sounding beep* (I wish I didn't have to work for Jedi...)"

- When E4 was in her second body.

Details
E4-XX is a skinny, and tall feminine pink droid. E4 was a mimic droid, but also used as an assassin droid.

History
E4 was either created before, or during the clone wars (or an era close to it, which could be the Civil war-and-Alphadroid war). "Her" creator is unknown. E4 was a drone prone to forgetting things. When E4's first body was controlled by the Darkside (somehow), E4 was put in a floating pink sphere-shaped body. When E4 beeped in that form, the beep sounded somewhat feminine. E4 was a droid, at this time, used by the Jedi, even though 'she' had a distrust of Jedi, she didn't voice it. After her Jedi owner died to a Sith, E4 switched owners quickly until she got into one-of-the-Daughters-of Makshakel-Fury's. E4's original, first body was coincendently found by the Fury legacy, and she helped E4 get back into her old body. E4 only really trusted her, but she disappeared. E4 then wandered around, mimicking a female Twi'lek. E4 randomly found a bunch of droids, and she hated them. E4 had switched to a Female human Jedi, and decapitated the droids. E4 stayed in this form, but had an internal fight with her own systems. E4's body had looked like her mimicked female Twi'lek, except the Twi'lek had a Lightsaber. E4 had then, flew to another planet. On that planet, Sharra used her to assassinate Sith lords.

Personality and traits
E4 didn't really trust Humans that much. Also said, around her first years, she was prone to forgetting things.

E4 also didn't like to stay in her droid form that much.

Behind the scenes
Since E4 was a Mimic droid (in her first, and normal body), she had many weapons at her disposal.
