In 2007, an assortment of Mecha from the Gundam franchise were reelased in construction set form thanks to Mega Bloks and Bandai. Three different Gundam inspired sets were released by Mega Bloks in Japan, each featuring roughly 800 pieces. The Gundam Mega Bloks sets included the iconic RX-78 Mobile Suit as well as the MS 06F and 06S units. Unfrotuantely, the Gundam Mega Bloks sets are no longer available, but for a experienced builder, re-creating these Mobile suits should be no problem.
