One of my favorite little quirks of TVTropes is that the people covering the Godzilla have a deep moral revulsion towards Gigan. Like, seriously, just search for Gigan and they have him in the same "Complete Monster" category as Anton Chigurh and Judge Holden.
"The freedom of giant cyborg chicken things is an insult to me. I'd have them all in zoos. That would be a hell of a zoo."
First of all, in Godzilla vs. Gigan, he was just a poor space dinosaur surgically mutilated and forced to be the mind-controlled slave of alien cockroaches. So no moral culpability there.
And in Godzilla vs. Megalon, the seatopians are pissed that people keep nuclear testing in their oceans, so they send out a giant beetle god (actually kind of feel like these last two movie's kaiju should have been switched, but that's beside the point). And once the beetle gets his ass kicked because he's stupid and drill hands aren't actually that productive, the Seatopians radio the alien cockroaches for help, drawing on some Ancient Atlantean-Blatta Accord that apparently exists in the same continuity as Gojira (1954). And so Gigan comes back to earth. To save the oceans' indigenous people from the ravages of nuclear weaponry. And he's automatically chummy with Megalon, who clearl needs assistance because somethings not all there.
Gigan is an environmentalist hero, and has empathy towards people in need, no matter how aquatic or chitinous. He's like Captain Planet if he locked the fuck in.
"OH, GIGAN IS SADISTIC, HE TORTURES HIS FOES."
Uh, so does Godzilla, all the time. He just toys with motherfuckers.
"OH, GIGAN IS A COWARD, HE ALWAYS RUNS AWAY WHEN HE'S LOSING."
Yeah, it's called a strategic retreat. Gigan is smart enough to know that once you get your HP wrestled down to 10, Godzilla's going to atomic breath you in the face. You're not a dirty coward for not wanting your head to be the next Trinity testing site.
I am become breath, destroyer of latex.
"OH, GIGAN SLOWLY DRAGS PEOPLE INTO HIS BUZZSAW."
Uh, yeah? He had his viscera forcibly ripped out and replaced with a buzzsaw. You expect him not to use it in his kaiju death battles? Excuse me? He lost his duodenum for that. He has to use colostomy bags. He has hooks for hands, the boy cannot wipe, let his use his one goddamn thing without moralizing about it.
Godzilla has atomic fallout for breath. You know what that shit does? You think using that in Japanese cities isn't problematic? The boy is a metaphor.
