The only comment saying where you actually get this companion has, at the time of posting, been voted down to -24, so I'm reposting to preserve the data in case of purging.

You get this companion on Belsavis.

SCORPIO has the following proficiencies:

Weapon Proficiency: Techblade
Weapon Proficiency: Techstaff
Armor Proficiency: Droid
Armor Proficiency: Heavy
Armor Proficiency: Shield Generator
Armor Proficiency: Power Generator

• Despite the main post, she can not use Electrostaff

SCORPIO is one of my favorite personalities; she's just delightfully evil! She's a beefy melee tank and mild dps, below is a transcribe from the Codex:

Name: SCORPIO
Gender: None (identifies as female?)
Species: Droid
Age: Unknown
Likes: learning and gaining new tech, selfishness, killing threats.
Dislikes: Self-sacrifice, duty, wastefulness

Primary Stat: Aim
Secondary Stat: Endurance

Primary Weapon: Electrostaff
Secondary Weapon: Shield Generator

Background (Summary): Claims to have been designed for heuristic self-improvement by unknown parties. Current chassis is of recent design, suggesting multiple precursor bodies or independent database.

Over a century ago, SCORPIO became involved with the Star Cabal organization and accepted guardianship of Belsavis Megasecurity Ward 23. In return for rare technology, SCORPIO willingly acted as the Star Cabal's security system until application of control codes by Cipher Nine. Currently unable to directly harm Cipher Nine without provocation or depart Cipher Nine's presence on a long-term basis.

Personality: Application of Wreyn-Tsatke Cyper-Psychology Scale results in 9-NIX rating for SCORPIO (Level 9 intelligence, non-human, independent, unknown) with 22% accuracy. These preliminary results match anecdotal experience-SCORPIO places no inherent value on biological or cybernetic life and is interested primarily in self-iteration through rapid experience. If given appropriate challenges and upgrade opportunities, SCORPIO may prove cooperative for limited periods. She appears to value others who share her traits -intelligence, amoral self-interest and curiosity.

Similar cybernetic personalities include Mentor (10-NCM) and GO-T9 (8-HSM) -both considered galaxy-level threats. Recommend full application of Wreyn-Tsatke Test at earliest oppurtunity.

Notes: this profle is a work in progress and should not be considered definitive.

Special: By order of the Minister of Intelligence, access to this profile is restricted.

For those who haven't played Knights of the Old Republic 2: The Sith Lords, G0-T9 is most likely a reference to G0-T0. An AI that was Republic made to oversee the rebuilding of Telos after it was destroyed by Malik (in KOTOR1) and was given an order that made it go insane. I don't remember exactly but the gist of its order was "to protect the Republic" or something like that, which made it turn into a Nar Shadaa based crime lord.

It seems that after crossing Revan's path and following him to Malachor V, G0-T0 went on to become a psychotic AI..... I always knew there was a reason to love that bastard.

Do be aware: Can't rename companions... and it's a female personality in that droid.

She also wants to kill you, but can't due to the obvious restraining bolt.
