The RegionGame's name comes from another kaiju's name in Gamera 2: Advent of Legion, Legion (レギオン?, Region), and Game which comes from Gamera's name.
Detail[]
The RegionGame suit is similar to the previous suit, but has some minor differences. The RegionGame suit's arms now have extensions on them which would lock into points on the suit when it was being used for flight scenes. The RegionGame suit's head is also slightly different to the HeiseiGame suit, and the bones of its skull are more defined. The suit's tusks are also slightly longer. The pattern of plates on the belly were also made larger so that the Mana Blast attack could be animated. This suit, alongside the IrisuGame suit, was made with softer materials in some parts, so that it could be damaged realistically by the Queen and Symbiote Legion suits and puppets during filming.
