Serina (AI Serial Number: SNA 1292-4) was a second-generation "Smart" A.I. that was assigned to the UNSC Spirit of Fire, a modified Phoenix-class colony ship commissioned by the UNSC Navy. Serina's avatar was a young woman with long hair and she spoke with a distinct British accent.

History
The history of Serina is the same as his mainstream counterpart.

Personality
Serina had a very sarcastic and detached nature. She frequently seemed to disregard the lives of others, even her own ship's crew - such as when the Spirit of Fire was slowly being pulled inside the Shield World - almost always responding to their peril with some curious remark or dark joke. Although prone to sarcastic comments and exhibiting a seemingly uncaring attitude, she was more compassionate than she seemed.

She also appeared to have a fascination with human relationships. Knowing the crew of the Spirit of Fire may be on a one-way trip, Serina manufactured and delivered fake emails from family members to the crew celebrating Valentine's Day. No one ever suspected her of this deception.

Serina also had several fragments of memories from her donor. Several of these memories include food, the smell of flowers, the feeling of grass on her feet, and a lot of other little moments. Relating to this during her free time, she tried to remember what chocolate tastes like, with little success. She also ran detailed simulations based on the memory of when her donor kissed a boy.
