I'd also add that ロック for 六 is not a connection that comes up a lot in Japanese. There is a subtle difference in the way the words are pronounced.

The number theory kind of bugs me because a lot of the arguments seem like basic pattern recognition - our brains are hardwired to find patterns in things, even when there aren't any. (this is why sometimes pictures of rocks from Mars look like faces and bodies) I think it's a case of people finding false positives and wanting something to be true enough that the most minuscule thing serves as justification. Hey, the Shift Cars look like a seven when flipped (they...really don't?), hey, that one Drive form that shows 777.

People use the fact that there are hexagons in Ghost as justification or that Mugen has the infinity symbol all over its body. They wanted Ex-Aid to be a continuation of this being thing rescue = kyuukyuu = 9.

So, what does "RX" of Black RX mean? I can't seem to find a good reason why they went with that lettering? I feel like it's suppossed to be a play on "Resurrection", but don't quote me on that!

The only thing even remotely close to being sourced I've ever found was a supposed quote from a radio program that says R stands for Rider while X stands for "unknown quantity", which is a reference to his multiple forms.
