The 'brute' mech from my Mobile Frame Zero company based on the 90's Lego UFO theme. The full company is visible here
I call it a 'brute' because it just looks vicious. This is despite the fact that I always figured the black-armored alien figure was the commander. I think I like the looks of this one the best out of the three that share the same design.
The "chainswordchucks" it uses are sort of an inside joke with an IRL friend of mine. And yes, those are transparent orange chainsaws. It's not very visible in this shot, but the shield it uses is actually made of a bunch of transparent orange skis. Yes, I had a lot of Ice Planet sets as well.
