Mini IMC Atlas Titan with a Quad Rocket from Titanfall. Built for TBB's Chibi Micro contest, but unfortunately I don't think it'll count since it's not a full minifig and it's a mech :/ Oh well, had a lot of fun with this build.
Standard hardsuit, provides full protection for pilot being cheap and maintenance-friendly at the same time. This is largely based on one of my favorite hardsuits by Chewk. I just made the proper articulation and added some guns))
