Miscellaneous derivative model of the Reaper synth, mouthline suggests Teratochoran-issue, or perhaps an imitation.

Attrition, possible Teratochoron markings.

Unnamed Gelidan, someone from Flocke's past. Heavy hybrid cyborg. Black facial marking and gold eyes standard to ice workers.

Attrition, humanform agent system. Not sure about the look. Trying to make her appear slightly old, huge, and not too pretty, as befits a humanoid warship. Keeping her hair and dentition the same as dogbot form. Her expressions are less cryptic without a doggy smile contaminating the signal.
