Firstly, I feel offended you reduced the giant mecha vs a dragon cinematic to robot vs a doll army :P

Ff9 did the “all powerful god” but it is really a wtf out of no where momement that can feel jarring with the themes of the game - a ludonarrative narrative dissonance, unless I missed some obscure reference to it somewhere

I would argue that ff6 wrote a less jarring “kill a god” fight:

Although pulling ideas from christianity, it has a psychopathic clown ascend to godhood, shatter the world and sit a top his “heavenly throne” shooting god rays from the sky on a whim The fight then is a series of killing his “angels” before finally destroying him and shattering his “heaven”
