I mean, while Showa Gigan is truly iconic, I just love how FW Gigan looks so over-the-top edgy, and I feel like it better captures his sadistic personality. Overall, both are great designs IMO.
Also, if I had used Showa Gigan for the animation it would have looked too similar to the Gigabash Godzilla DLC trailer.
Funny how back then we thiught robots and ai would take care on household chores so we could focus on more important stuff, but now it’s the ai who’s doing work, art, music, and basically everything else because a lot of people are just lazy
