Here is Yellow story of how he came to be. . . That will probably get my ran out of the Fandom for the reasons behind it, But Hey, I got Kusaka covering my back so bring it!
Any way, when I just barely got the internet back in summer of 03, I went to various PR board since I was still intrested in it then (I hadn't heard/seen much of Sentai so I still had no clue there was anything more than PR, God I'm GLAD that changed.) But I wanted a PR related name without being "[Insert Color here] [insert random word here] Ranger" or worse one of the "Forever[insert color here]" names. Then suddenly in a brain fart, I remember the Wild West saga from MMPR and the "White Stranger" and named myself "Green Stranger" for a while. And it was all going good until I ran into a poll at the main board I was browsing (Long since gone sadly) that covered the ranger colors in user names and was shocked suddenly that Yellow had NONE. (Ninja Storm was airing and Dustin was my favorite ranger).
Since that board allowed the users to change there names freely, I suddenly changed my name to Yellow Stranger. I orginally intended it to be a short while, but over time I grew fond of my Alias and continued to use it when that board merged with PRN(Now Ranger-Power). I changed it for like a half year during DT cause I found the concept behind the Triassic Ranger/Abaremax to be awesome. But thanks to the "Hyper Kabuto" of PRdom, and my fondness of YS, I changed it back for SPD and keep it as my online alias since (Expect for a few forums where I knew I wouldn't be posting much anyway).
So yeah, That's my story, and I'm sticking to it!
