I built Erkebala back in December 2012, out of assorted pieces from Master Builder Academy, Mars Mission, Ninjago, and Hero Factory.
About this creation
The robot came in a series of four stages, but the second and third ones are the most important.
In the second stage, I built the robot in three directions that I could take, each using pieces from a particular theme.
After building the prototypes and receiving some feedback on them, I set to work on the next version. None of the three prototypes had as much white as I wanted, but the combined version would fix that. I also didn't want to make the fins on the shoulders too long.
Here he is without his grappling hook. I originally wanted him to have a mace, but I just couldn't get it the way I wanted.
And here's a close up of the head:
I have a newer backstory in the works, but it's not ready yet. For now, let it suffice that he is powered by a frozen energy core, and fights on the side of the good Confederation.
