He doesn't really have a dark side per se....he is plagued with insecurity since his battle with Kyoya and that is how L Drago's dark energy is able to start to mess with Tsubasa. It is later revealed that LDrago's energy flowed into him during battle bladers and is using his insecurity and painful memories to get him upset in order create negative energy and increase its control over him. But he has finally figured out how to disconnect from it with Ryuga's help. I wonder if it'll be an issue again in 4D?
