VS, 90s or Heisei series (1984-1995)

The VS series is in the era known as the Heisei Period wherein, when not only did Godzilla return after more than a decade's absence, but marked a transition between the reign of the Showa Emperor Hirohito to that of his son Akihito, now dubbed the Heisei Emperor.

The following films showed mankind's efforts to defeat Godzilla while also being challenged by other monsters such as Mothra, Rodan, and SpaceGodzilla. This series featured a specialized organization of monster-combating soldiers and engineers called G-Force. Several of the ways ways G-Force planned to stop Godzilla included the construction of two "mecha-kaiju", MechaGodzilla (who would do battle with both Godzilla and Rodan) and M.O.G.U.E.R.A, also called Moguera (vs. SpaceGodzilla).

Like in the previous series, Godzilla eventually adopts a "son" that is discovered by scientists in Rodan's nest, this time simply called "Baby Godzilla", "Little Godzilla," and "Godzilla Jr," simply referred to as "Junior." It is never stated that Godzilla birthed (asexually) the monster itself, or even made clear whether Godzilla had any knowledge of the creature's existence before it was born. Both Rodan and Godzilla had a natural drive to want to be close with the monster, much to the tactical benefit of G-Force.

Ultimately this Godzilla would meet his end in the finale of the versus series, Godzilla vs. Destoroyah. Everything comes full circle when Godzilla is faced with a monster, Destoroyah, created by the Oxygen Destroyer, which was used to kill the first Godzilla in 1954. (Burning) Godzilla's end came when his internal radiation became too intense for his body to control, and he finally succumbed to a total nuclear meltdown. This was not the end of Godzilla's legacy, however; the previously wounded Godzilla Junior (who was killed by Destroyah earlier) absorbed all of the radiation from Godzilla's meltdown and fully matured into an adult Godzilla.
