First off, did you seriously just Google me? That is insanely creepy.
Secondly, CoX ended in 2012. Kamen Rider Drive, and the official character Mach, did not exist until 2014. So unless you want to argue I'm clairvoyant or a time traveller, then the fact is I happened to pick a name and theme loosly similar to something Bandai eventually did afterwards.
I googled your screen name, because it looked familiar. Not exactly the same as googling YOU, as a person. THAT would indeed be creepy.
As for Kamen Rider, that franchise has been around since the 70s. Hell, as old as I am, it's older than me. So please, spare me the idea that your character is a completely original concept. There is nothing wrong with remaking characters, whether completely or using costumes, etc. I have 2 toons that do so, in a sea of original characters.
