Milsha's weapon is pretty high technology. I wouldn't really say it transforms. It's a bigass sword that's hollowed out on the inside so that a variety of other weapons could be installed, like a flamethrower and harpoon launcher.
I figured, dimensional pocket technology (which is the only kind of science I think can explain things like Pokeballs) existing in this world allows for really high levels of technology, such as androids like Wilhelmina, the RDPAs, and the advent of human/Pokemon hybrids.
