Fun Fact:
Rain was my very first OC that I made back in 2012, being Tails' older brother even though he's mostly a Tails recolor with pants. After a year, I ended up forgetting he existed as I was into anime a lot. It was thanks to the Sonic Movie that brought me back to the fandom. I ended up making Zack and he was remade as Zack's brother. Left side was his design back in 2012, and the right side is his glow up now.
