The second prototype body for Matrix had to be toned down after the higher-ups in the lab started to get nosy. Matrix didn't really mind too much as the new, improved and less bulky body allowed her to interact with the public for the first time.
The only real issue she had with her body was this time around she didn't look female at all, which was the sex she preferred to identify with. To add insult to the injury, they let her keep the male parts, albeit significantly downsized to keep the questions of the general populace down.
Later models became modular, with interchangable parts, but this AI never got over the loss of her favorite body parts and finally rebelled completely, kidnapping the scientists responsible for creating her and forcing them to gather parts to build her a new body under threat of being shrunk and swallowed to provide power to her circuits.
There isn't really much to say about this one.... Just wanted to make Matrix look a bit less awkward than the first time around... Drawn with people looking over my shoulder, so teh sexy was left out this time.
