Gigantor Mk-II is the more powerful successor to the original Gigantor. It resembles the original Gigantor except it had a red "V" plate on the chest like Great Mazinger. Unlike the original Gigantor, which was remote controlled, Gigantor Mk-II is piloted from inside. Gigantor Mk-II can only be powered by either a super powered being or someone from the Gurren Lagann-verse who has Spiral Power. Gigantor Mk-II functions similar to a Lagann as it can be activated by a Core Drill. Gigantor Mk-II can combine with the FXA-06D Super G-Defenser to form Super Gigantor. Gigantor Mk-II was eventually succeded by the more powerful Zeta Gigantor.
