Cyan had a normal childhood. His first Bakugan ever was a Darkus Laserman. He found that Bakugan, while was returning home from school, hardly damaged, and almost alive. His father, Mr. Tohiro, was a scientist, and a doctor, so he repaired that Laserman. From that day Cyan and Laserman were best friends. However, one day a stranger challanged Cyan and Laserman to a battle. The stranger won by cheating, and in the battle destroyed Laserman entirely, leaving from him only dust. For Cyan, that was the saddest day of his life, and he promised himself, that one day he will avenge the lost of Laserman. Two years after that, while he was returning from school, he found a strange-looking closed Bakugan . When he got home, that Bakugan would not open or say something, but just remained as a closed ball. On the next day, Cyan was woken-up by something, which said to him to wake up. That was that Bakugan, who seemed very friendly, and said "Hello" to Cyan. The bakugan introduced himself as DarkShine, a Cyber Bakugan that battled a unknown evil in New Vestroia, but in the process got roughly teleported to this world. From the rough teleport, he was quite shocked, so he couldn't open or say something. Cyan and DarkShine became friends, and DarkShine became Cyan's Guardian Bakugan.
Later in an attempt to defeat the Neutral Core, he was sent in out of any dimensions and removed from any time. He was there for Infinity, thus his mind evolved and he transformed into Strike.
