The prefix "ultra" is due to the name of giant Japanese superhero Ultraman, whose size ranges from 40 to 50 meters. It is also the most popular size of the tokusatsus, whose kaijus and mechas barely exceed 100 meters.
Because there are many (and very strong) disagreements within the GTS community about when a giantess should carry the prefix "ultra" (some conisderan well when they are larger than planets, others place them at an intermediate point of the mega-GTS and giga-GTS, and others relate them to the size of Ultraman).
In this wiki will opt for the definition given at the beginning of the article, since the prefix "ultra", to most people, reminds them more to Ultraman. On the other hand, it would be unnecessary to define ultra-GTS with other sizes when there are already other terms that already cover such sizes.
