Here's another mecha, again adapted from David White's book. White's main style of mecha design is built from blocky squarish shapes, but depending on the technology a mecha could be curvy and graceful too. I think about what shapes would deflect incoming fire and move easily on the battlefield. Old-fashioned knight's plate armor would be a classic mecha design idea, and there are plenty of them around, but there are other models for battle robots, such as hard-shelled insects or crustaceans. Imagine a Fighting Lobster on your side, with lasers coming out of its giant arms. Or a Fire Ant, with a flamethrower as well as a sting. The possibilities are myriad. Note the mechanical "grinning skull" headpiece of this figure. The Warhammer universe designs are filled with skulls of all sorts, the bony skull seems to be a characteristic of many fantasy fighting figures.
