The Sniper Robogirl, named Heartstopper is the creation of icemonster. This Lego mech features a full range of motion, thanks to all the balljoints. She uses a lot of Bionicle pieces, which blend in well with all the other Lego bricks. Check out the visor/binoculars and those hands. The pink highlights help the design stand out too.
