Damian Hart

He is the captain of Team Star Breaker, a Beyblade team that represented the USA in the Beyblade World Championships; Big Bang Bladers. Being the one and only owner of Hades Kerbecs BD145DS, Damian is one of the strongest bladers in the world, having undergone the highest level of arrangement. When he was discovered by the HD Academy, his strength was enhanced through the Arrangement System developed by Hades Inc.

He was a ruthless and fierce Blader in battle who only wished to send his opponent's Beyblades into the dark and despair of Hades. As well, he was loyal to Dr. Ziggurat, the coach of Team Star Breaker and the man responsible for the creation of Hades City.
