Draken is a lanky teenager who is exceptionally tall for his age. His head is shaven on the sides and back to expose his signature dragon tattoo. His blonde hair is longer on the top, but is kept neatly braided. He leaves a few strands of hair lose in the front. He is confirmed to be quite lean and has abs. Takemichi has remarked that his body does not seem like that of a teenager. He wears the standard Toman Toppoku while with the gang and his favorite outfit seems to be a patterned long jacket.
Like the president, vice-president Draken is also quite the wild individual. He loves a good fight and relishes meeting strong opponents.
Unlike Mikey, Draken the more mature and logical of the two. When Pah-chin decides to take the fall and responsibility for Toman by deliberately getting arrested, Mikey tries to get Pah-chin to run. However, Draken stops him, saying that it is the right thing for Pah-chin to do.
As Toman's vice-president, Draken's fighting prowess is incredibly fearsome. When he is hit in the head by a metal pole, he is still able to stand and defeat 20 opponents. His recovery is remarkably quick as he quickly heads right back into battle when reinforcements shortly arrive. He even survives a life-threatening knife wound.
His power is so immense that when healthy, he defeats a whole gang by himself, which is about 50 people, and is still standing after that. It would not be a stretch to say that his strength is comparable to Mikey's.
