The ocean duelist Mako Tsunami was known for dueling with honor and using a deck that contained mainly sea creatures. He knew the fury of the deep firsthand. His father had been a fisherman who sailed the world's oceans and was lost to the seas. Mako entered the Duelist Kingdom Tournament so that he could win the prize money and purchase a fishing boat to continue his father's legacy. Mako included the card The Legendary Fisherman because it reminded him of his father.
