You've got to hand it to Henrik Pilerud, creator of this seven-foot-tall Blood Angel Space Marine armor from Warhammer 40K, because if he tries to hand it to you he might crush you with his massive, articulated fist.
Pilerud basically took over the 2013 installemnt Swedish gaming convention Lincon wearing this amazing suit, which took him 400 hours to build over a period of ten months. You can get an overview of the process here, along with additional pictures of the amazing costume build.
