Three androids that I use on a MUCK regularly and all from a common story. I decided to draw them all to scale with luggage and a soda bottle as references for their sizes. Joule is the youngest and was engineered by Faraday for the greater part. The massive tails on the others are energy skimmers. Mostly light antennae and such in there, and typically used to power them on their homeworld where excess RF and microwave energy is abundant.
