A warm up sketch I did this afternoon that ended up being Kamen Rider Deimos related so I went along with it. I decided for the setting to be in Mars and it's many colonies.
Extal Veida, a well-known underground Shadow Courier (Think of the movie 'Transporter') is hired by someone to deliver a briefcase to an android named Phobos living in a nearby Martian colony. Upon reaching his destination Extal and Phobos are attacked by monsters that claim to embody the spirit of Mars. To Extal's surprise, Phobos transformed into Masked Rider Phobos. Phobos ordered Extal to equip the belt contained within the briefcase and transform into Masked Rider Deimos.
