Literally "combination" or "union," generally refers to the fusing of mechs.


The world gattai mean combination or fusion in Japanese, used when multiple robots or mecha transform to merge with each other. Most of time when the main characters' robots merge they become strong enough to take down their enemies, which is at this point considered as cliche of many mecha series. However this concept is not used in all mecha series, it is mostly used in super robot shows and not in realistic robot series.


  • Extension - The robots that are part of gattai formation transform themselves to become limb of bigger robot.
  • Armament - While one remains its robot form, the other robot that is part of gattai formation scatter and attach itself to main body
  • Weapon - One, or sometimes more, robot transform and becomes a weapon such as sword or cannon. This one can be questionable since they don't exactly combine to each other. However there are instances where the weapon robot and main robot attach to each other.
