Mega Man RPG Prototype Community

Ever since 2017 (Technically 2015 because somethings were removed), we had 15 Other Robots Presented in MMRPG Prototype before the final product in 2018. They are: Shark Man(.EXE), Blossom Woman, Desert Man, Zephyr Woman, Target Man, Hallow Man, Prism Man, Portal Man, Shield Man, Laser Man, Planet Man, Cosmo Man, and the 3 Dark Frags (Dark Frag, Dark Spire, Dark Tower). The First 10 have a PCR Number (which I don't know what it stands for), while the next 2 Have a Continued EXN Number (which I would like to know and there is only X and Y). Lastly the Dark Frag, Spire, and Tower have a DRK Number continued with 4 Letters of it's Last Name (FRAG, SPIR, TOWR). I would just like to know if you are planning to let these be used in MMRPG World or just to be placed aside from the game
