FF3SE 2.14

Is there a way to edit the first 3 forms of the final boss? Can't find their sprites in any of the versions of FF3SE. Only the very last God Kefka. Thanks to everyone in adv.

That's because they aren't sprites; they're part of the background image, as you can see here https://www.ff6hacking.com/wiki/doku.php?id=sprite:bgs. Probably the easiest way to edit them is to use Everything's FF6Tools.
