I like to imagine Drumbot Brian as a multitool. Tim forgets his amp? Oh, just plug into brian. Ivy's food got cold while she was reading? Brian, the microwave's all the way over there---could you hold this for a minute? Nastya's making parts for the aurora? Brian's got impeccable spacial reasoning bc ai brain; that's why he's pilot.

On the other hand, he's a tool. In a body where his choices are invariably externally influenced, he has so many add-ons designed to serve. His crew treats his preferences like an inconvenience and his body like a tool.
