What are some mecha that are confirmed to be in the public domain outside of Jules Verne stuff? Just saying, it wouldn't be hard to make some mecha stories with pre-established legacies a d put it on Amazon Kindle.

Air Fighter Comics from the 30s through the 50s never renewed their copyright so there's a bunch of comic planes and characters from those that would be PD. Pretty sure you can find Nazi robots in there too.

The Wizard of Oz books are in public domain and they have a hot-blooded warrior king who has a belt that lets him transform.
I am deliberately leaving details out of that description.

Also Oz does have multiple living automatons ranging from robots to cyborgs to sentient piles of junk.

Quite a bit of “Mechanical men” silent films, you can easily find them on YouTube, they’re some of the earliest movies to feature “Robots”

I'm pretty sure these guys are public domain

There's a fair bit of public domain floating around out there, the problem is that very little of it has a "legacy" outside of Verne and Wells. Like yeah you can take whatever you want from the Edisons that were all over the 1890s, but they're from the 1890s.
