The missile-toting heavyweight Virtuaroid in Virtual-On: Oratorio Tangram.
About this creation
Simple back view.
Took about a week to make. The shoulders were surprisingly easier to do than expected, although they still caused some issues. I put the Orange Transparent Chainsaw there for luck. This was based off of a Japanese Dia-Block creation, which I attempted to modify to be makeable in LDD. The biggest issue is getting around spacing, since Dia-Block's plates are thicker than Lego's plates.
