The reason why I support this couple is because this is the very first reason why I joined this club. My first Sonic game was 'Sonic Rush.' I started to grow addicted to it, epically Blaze. When it came the end of the game with Sonic and Blaze floating to each other, my first thought was that they were gonna kiss,(I wish) but instead they shook hands. When they started to separate from each other they held to each other tightly until both of them let go. So after that I was a Sonaze fan. So here are my reasons:
1- Sonic is the one that taught her friendship. (besides Cream)
2- They both saved each others world, twice.
3- Blaze (or Percival same person, but different life) blushed when Sonic's sword said "Save the hugs and kisses for later." So that means she has something for him.
4- They both shook hands at the end of their adventures.
5- Sonic was looking at Blaze after he defeated Dr.Eggman at Sonic Rush. But he said nothing when Tails asked him what was wrong.
6- They both seemed to be drawn together por the Chaos Emeralds and Sol Emeralds in Sonic Rush Adventure.
So there are my reasons (and some other people's reasons). If you don't like what I put then don't comment. (Although you still are, I'm just saying before you do.) It may be worded weird, but oh well you know what I mean. If you're a Sonaze fan, you can put some other reasons why you think they go together.
