It's a bit odd to combine the idea of this post with the one on paralyzed people sending texts with their minds. Paralyzed people controlling other creatures via their minds. Sort of a cyberpunk familiar / spirit animal.
Reminds me of the rat thing security cyborg dog in Snow Crash. Powered by a small nuclear device, it runs faster than the speed of sound to stay cool and resides in a liquid nitrogen cooled hatch when not moving. Completely ridiculous of course. But fun.
We got the cyberpunk future, and we also got... Animorphs.
