Suggested by Sonic Hikaru is one of those characters who is a real blast from the past since Dragon Drive was one of the first ever manga that I read. He’s a skilled fighter and his dragons are very powerful. The reason he loses here is more a battle of numbers. Kai has dozens and dozens of dragons at his disposal and the higher end ones are incredibly powerful. There isn’t a way for Hikaru to combat them all. I think he would take most down for the count but ultimately he would not be able to win. Toshiki Kai wins.
