Added spoiler tags. Just so that it wouldn't look too messy.

1st Place Vote: 2nd Gen, #13 - Ranger

I'm liking how the core and the orange detail on the head show off a nice contrast from the rest of the parts; it has a very clean look. The rifle and radar match the whole color scheme too, so I'm guessing it was prolly built around the two. Reminds me of general purpose ACs, with this one configured to conduct reconnoiter.




2nd Place Vote: 1st Gen, #8 - Master Of Integer

Kind of the same reason with Ranger. The pattern seems to match the launcher's color, nicely revealing details of the AC's bulky parts while also avoiding unnecessary details/wild colors. It gives off the impression of a well-armed, customized machine. It's as if someone retrofitted the thing with some reactive armor plating to cover the legs from explosive projectiles.




3rd Place Vote: 4th Gen, #5 - Cosmonaut

There's uniformity, and it does look like some kind of cold war-esque humanoid drone. Even the parts look like they've been built to operate in space. Could also be some kind of power suit that cosmonauts use for heavy duty tasks.
