I think I've still got writer's block, and I am so, so sorry for making you wait so long! I came up with an idea, though, so the writer's block is going away soon. The Raving Maiden will be a repurposed Warp Fighter, a relatively small vessel designed for about 3-6 crew members. Made up entirely of SEED, Warp Fighters are a form of artificial life, complete with a brain and central nervous system. This gives them a tremendous amount of survivability and autonomy, at a cost of computational performance and reliability. Their substantial individuality is both a blessing and a curse; it can make them supremely capable or unfortunately stunted. The Raving Maiden is among the latter, designed as a combat ship, but with little of the mental capacity for one. Thus, she was robbed of her Q-Core (Quantum Singularity Core - a black hole, basically; an immensely powerful reactor) and turned into a civilian vessel.
These features are not broadly known, however. Warp Fighters are better-known for their transformation abilities (which the Raving Maiden lacks, due to not having a Q-Core), and are rather famous for their sleek and powerful humanoid forms. When the troops needed heavy armor and firepower on the ground, the Warp Fighters filled that role. Their designers wanted them to take on a more tank-like appearance for ground combat, but the humanoid form was the Warp Fighters' own choice, and the designers had little say in that. :P
In short, the Raving Maiden is a character all on her own. ;)
Our first mission: Locate the Raving Maiden's Q-Core!
