Power Rider Medal Scrambler (OOO adaptation/expansion) - First draft
 

There’s a lot to unpack. Shingo is genderswapped and doesn’t die, but Ankh has a full humanoid body from the beginning, which means he can assume a human form without needing to take a human host. The now-sisters both gain Rider forms using the pachinko machine-based Mutation Driver.
