Kastelan Robots are probably my favorite model in the Adeptus Mechanicus line of Warhammer 40,000 models. They're big stompy bots, which aren't cyborgs and need to be controlled by a handler in order to operate on the battlefield.
They also are very old, in 40k terms, older than the Imperium of Man. That gave me plenty of ideas to go with.
For my army, I knew that I wanted to have the robots in diffferent colors than the green that is seen across the rest of my army. The idea being that these guys collect robos and use parts from other fallen robots to rebuild two downed robos into one operational robo.
The first of many Kastelan Robots, this guy was my test run on painting them as much as he was also my first one for my army. His eyes were also the subject of my tutorial on painting glowing eyes.
Let's take a look.
