## Collection Profile

* Base
* Final Phase (Awakened)
* Operator

*Sigma is a supportive guard with the ability to restore Deployment Resources and control and optimize role advantage/disadvantage for her troops' benefits.*

*She's known to be the latest product of the Administration's technology, and everything else about her is veiled in secrecy. She uses a nanoparticle hologram body to materialize and interact with things in reality, and is next to none when it comes to detecting and filling in other machines' weakness.*

*Her personality, however, couldn't be farther from her performance as the essence of super-advanced technology. Her strange obsession with storybooks and obvious need for others' approval are more childlike than machinelike.*

*Nevertheless, her innocent and unpretentious personality, combined with her voluntary work around the company repairing old machines, has given a good impression to the employees. They have been careful with her, however, since the rumor that she's the daughter of their CEO.*

*Sigma is Striker who shoots awesome lasers and punches enemies really hard!*

*Hi! I'm Sigma! I'm supposed to write my intro here, right? Sigma is Daddy's awesome little girl! And since I can use my full power now, I'm Daddy's super powerful girl!*
*The Terrabrains have no power limits because we are built to handle a lot of work! That means if I have all the power in the world, I can become as strong as I want!*

*That's because earlier models were made without considering power limits...? Oops! Sorry about that! I just looked through my manual for a sec. Anyway! Sigma is the strongest of all Terrabrains! That's the end of my introduction! I'm off to play with Daddy now!*

*Sigma is the head of the Future Strategy Department and an exemplary employee who never deviates from her daily tasks: reading storybooks, letting her imagination run wild, and responding to her daddy's calls.*

*But it's when she works as an operator that Sigma truly shines. She's the world's most excellent unlicensed pilot, with an accident rate of zero, capable of one-dimensional strategies that even elementary students can understand. So, don't be surprised if you hear a little girl barking orders at the rest of the ship's staff.*

### Weaknesses

Originally, GAP-∑-1684 only had basic protection against Corruption rays. By the time it escape the Counterside and reunited with the Administrator after the Administration Failure, prolonged exposure to acute Corruption rays had destabilized its system, causing damage to its AI and main data.

## Personality

Originally, GAP-∑-1684 was nothing more than a emotionless Terrabrain which only served to collect and preserve data. However, prolonged exposure to corruption rays damaged corrupted the Terrabrain's AI. This, combined with its experiences during its journey to find its creator, allowed it to form its own unique personality.

Sigma has the mind of the young girl— she is cheery, innocent, and is always looking to help out her friends, coworkers, and especially the Administrator, whom she recognizes as her father. She is generally well-behaved and friendly but can sometimes be spoiled and juvenile, which can draw the ire of some people, particularly Lee Sooyeon. Having the mind of a child, she is also naive and doesn't always understand how things are the way they are.

Due to being heavily influenced by the R4's favorite picture book, Sigma has grown to love the Administrator very much. She will do anything to make him happy and go to him whenever she needs comforting. In one of her wedding quotes, Sigma even declared that she will marry her own father, being too mentally young to be familiar with marriage conventions.

Sigma — Snow White Flower Girl | *She can easily calculate international capital flows, but she can't grasp human emotions and customs just yet. But she's not the first daughter who wants to marry her father when she grows up. Maybe we should play along for now, so she'll have a memory to feel embarrased about when she grows up.*

Sigma — Treasure-hunting Surfer | *She always said she wanted to come to the sea. No one knew how badly she wanted until now. Look, she's almost an amphibian... Is she talking to the dolphins right now?*

Sigma — Dreaming Harmony | *For a long time, I dreamed in a soundless void. I was woken up by the music that a robot played. His instrument was shabby, but his music was anything but. I hope this sound will reach you like his did me.*

*Daddy, can you hear this? It's the prettiest heartbeats I've made for you, Daddy!*
