We’ve featured a lot of Gundam mecha over the years, but this is the first time we’ve seen a mech from the anime Big O. A humongous, lumbering titan, Big O wields vengeance upon his enemies, and it’s no surprise that builder Moko, whose builds frequently grace this site, has excellently captured the mech’s hulking frame in brick form with this amazing minifig-scale version. Big O even features his O Thunder guns hidden in his arms.
