The Blaster! While the Senkaishu faction was basically the 'first' because the first few units ended up in it, I didn't quite solidify its design language until a bit later on in the project. This design was at a point where I ended up quite happy with the contrast between sleek paneling and exposed mechanics, heavy duty weaponry, and color breakup.
