And so I made this, inspired by both trees and Splitface's half-and-half armor design. His chest armor has even been used there.
Backstory: This is an experiment at half-organic mecha by war machines designers in the Sigma Sigma area. It turned out as a half-plantlife half-mechanical, sentient, intelligent drone made out of scrap. It fought in the Last Great Mecha War alongside the Museum Mecha and other battle drones. Now it's just a piece of junk in the War Museum of Sigma Sigma. But it is set to awaken and drain energy to get an upgraded form soon.
Behind the scenes: It's REALLY made out of scrap. I managed to find good uses for some not often seen system pieces such as trees, leaf, Avak's minifig weapon and that basketball piece in the left upper arm. C&C welcomed.
