So I was supposed to do this like, six months ago. Saw Entropy on my shelf and decided to finally do it!
The build is almost entirely simple stuff so this shouldn't take too long.
We're gonna start out with the easy stuff: His legs. These are really just basic Piraka leg frames with some Technic for the thighs. The small System build fits into the back of the leg using the clip to fill out the back without hindering articulation.
Next up is the head. I've included the scarf here since it's so important to his visual, but it's a very simple piece of black cloth with a hole in it to loop back on itself. Otherwise, everything else should be simple enough.
Combine the builds, squeezing the two System constructs inside the handguard of the two middle wing pieces to link them together with pressure. Last, grab one of those little System bits as shown, or find something else to finish out your flair.
Hopefully this was insightful and/or useful to you. Designs are all just designs, feel free to use them but I highly appreciate being credited for my work. Thanks!
See ya round.
