Now here are the main tropes related to War of the Gargantuas:
 * Axe-Crazy: Gaira is just one big, bloodthirsty brute.
 * Behemoth Battle: The brown Gargantua is a good guy who likes and protects humans. The green Gargantua is violent, savage, and eats people. They are brothers who were raised separately.
 * Berserk Button: Realizing that his "brother" eats humans appears to be Sanda's berserk button.
 * Cain and Abel: More like Abel and... bad Abel, since Gaira is just a wild clone of Sanda. The reference is still made by the film's characters.
 * Daylight Horror: On a cloudy day, Gaira makes landfall, and again when he attacks hikers on a mountain when it's foggy and cloudy.
 * The Determinator: Sanda is determined to stop Gaira's rampage, even while suffering from an injured leg.
 * From a Single Cell: Like their predecessor, Frankenstein, both of the Gargantuas can regrow into whole beings from just a piece of flesh, as Sanda undoubtedly was grown from the hand that Frankenstein lost in the previous film.
 * Gentle Giant: Sanda, much like his progenitor, Frankenstein, is generally kind and compassionate, even going so far as to try to reason with Gaira during their fight in Tokyo. Gaira, however...is a different story.
 * Giant Equals Invincible: Subverted. Gaira is generally impervious to most weaponry at first, thanks to his healing factor, which he inherited from Sanda and Frankenstein, but continuous fire does appear to affect him, even if only for a short while before he gets used to it. He is, however, vulnerable to maser fire and electricity, especially when there's an electric current flowing through the stream or river that's he's standing in.
 * I'm a Humanitarian: Gaira, for some reason, decides that humans would make a better meal than the giant octopus that he just defeated. It's a bit worse when one takes into account that Gaira and Sanda are born from Frankenstein, and essentially mutated humans, making Gaira a cannibal.
 * Motherly Scientist: Akemi was this to the young Sanda, like her predecessor, Dr. Sueko Togami (also played by Mizumo) was to Frankenstein.
 * Nature Vs Nurture: Gaira is Nature while Sanda is Nurture.
 * No Pronunciation Guide: Gaira was oddly romanized as Gaillah and pronounced as Gaiya in the export dub and all versions based on it.
 * Recycled Soundtrack: While this was common for Ifukube, especially with his tight schedules, here it seems almost deliberate, as both Frankenstein and Baragon's themes are reused as a way of reinforcing the connection between the two films.
 * Sibling Rivalry: Gaira and Sanda's differing views of humans is what leads to the titular war between them.
 * Weakened by the Light: Gaira, but subverted in that he can still walk around when it's cloudy outside, although he prefers the dark.
 * Worf Had the Flu: Interestingly, both opponents are not at full strength for the finale. Gaira has numerous maser burns while Sandra is having trouble moving from a broken leg.
