The premise is that she has an organic brain inside a synthetic body. The brain would need food, water, and oxygen to survive, but a greatly reduced amount compared to a full human body. These needs would also be regulated and buffered by the synthetic systems. A chemical oxygen generator and CO2 scrubber can be hundreds more efficient natural hemoglobin, allowing her to hold her breath for hours if necessary - although that would be uncomfortable as the brain is accustomed to breathing.

The brain would also still require sleep, although the requirement for the "slow wave" period where they body repairs itself may be reduced. So she may feel suspiciously un-fatigued at times.

A synthetic body would probably need to repair itself though. Think about it, how many times can you bend a usb cable back and forth before it stops working, how long do your clothes last? Anything soft is going to need to be self-healing or it'll turn into dust in a matter of months. And then there's the matter of expendable lubrication.

So I'd imagine she'd have some kind of digestive system and eat small specially prepared supplements. I had an idea for a little story page about this.

For power, she'd probably have to be nuclear. You just can't get enough power density out of chemical batteries and the charge anxiety would be too much. I had an idea where when she's first installed she's on battery power and feels cold and lethargic, then she goes down to the reactor room to have her permanent power supply installed and immediately feels much warmer and energetic.

Just playing around with the character a bit. Her familiar transforming back and forth is one idea.

Another idea is that since the bespectacled summoner has a talent for manifesting humanoid demons, she ends up serving as an ambassador of sorts.

I start with a general concept, then build up an outline with a few scene ideas, then move on to a specific page breakdown. The page breakdown will have dialog and actions written out, sometimes it's just [they argue] or [they fuck] and I fill in the details later.

I usually have the entire page breakdown written before starting a comic. For this comic I would sketch a few pages, do the dialog to make sure the page breaks lined up, then color that batch, then post and start on the next batch. If you're asking if I made this up as I went along, no - the loop was the concept from the beginning. When I got the the overlapping parts I massaged the dialog and action a bit to make sure things mostly fit with what I had already written.

For the next comic, Crossworld VR, I rough sketched the entire comic with complete dialog before coloring anything. Partially for efficiency but also since it was a commission I wanted the customer to approve the plot before I commit to a huge amount of work.

Worse!
