The Block Chest design started with this version.
I wasn't exactly happy with the way it looked and the one stud connection from the chest to the waist was way too fragile. I did like the way the legs looked though. So I worked a bit more and it became this.
It has the same essential shape, just smaller. He has a brother.
After a building spree I added a few more to the lineup and modified the Prototype into something I was happy with. Here's the squad together. (It's not the greatest of pictures.)
Here are a few specialized versions.
This is another picture of the first Block Chest mech in a more limber pose.
You can see it's a fun little frame that can be modified into multiple variants. I should have a few more pictures to share with you soon.
