The third part of the characters belongs to appliance/mix robots.
They are robots assembled from parts of household appliances or electronic and even more complex devices. Their special ability is to
'switch on' and provide extra resources to the player. In the world we are in, the resources for building robots are 'scrap'.
The design of these characters should contain a yellow color.
Each character took me about 8 hours of work, including searching for sketches, line work, color selection, and rendering.
