Yu - Gi - Oh ! - Episode 007 " Attack from the Deep " , known as " Sea God Leviathan " in the Japanese version , is the seventh episode of the " Yu - Gi - Oh ! " second series anime . It first aired in Japan on May 30 , 2000 and in the United States on November 10 , 2001 . Summary . Joey celebrates his two Star Chip s . Téa wonders if there ' s a time limit on how long he gets to crow , but Tristan tells her to cut him some slack , asking did she ever believe Joey would actually beat Mai in a Duel ? Yugi says he knew Joey could do it , and tells Joey he ' s proud of him . Joey ' s stomach starts to growl , and he asks if any of the others brought any food with them . Finding out no one did , Joey wonders , how will they get through the rest of the competition with nothing to eat ? Téa starts to freak out , saying they ' d better do something fast , saying that she ' s got to have her five basic food groups . ( In the Japanese version , Anzu ticks off the tournament organizers for not providing food for the participants . ) Tristan says he ' s got it covered , but in fact all he ' s brought is an outdoor survival guide . Tristan says it lists all the roots and berries they can eat . No one ' s impressed . But then Joey smells something cooking , and takes off . Téa thinks Joey ' s hallucinating , but Tristan reminds them it wasn ' t Joey ' s brain that beat Mai , it was his nose . They all follow Joey . At the edge of a cliff overlooking the ocean , they find three fish cooking over a fire . Joey rushes to dig in , saying they should eat first and ask questions later . ( In the Japanese version , Jounouchi says the gods laid that food there for them to eat . ) Téa protests , and Tristan says some people have no self - control . Then he takes off after Joey . Soon they ' re all sitting around the fire , while Joey and Tristan prepare to dig in , calling out , " Feeding frenzy ! " . ( In the Japanese version , they say " itadakimasu " , a typical statement made before eating . ) But before they can take a bite , the catcher of the fish rises up out of the sea , telling the fish thieves to enjoy themselves , this is their last meal . How dare they eat his fish ! But as he rails at them , a wave washes over the rocks and sweeps him away . Joey ' s wondering if they can eat now , when a hand rises over the rocks . The fisherman stalks over to them , and Joey tries to calm him down , but he goes on telling them off , shaking his fist . Yugi notices his dueling glove , and realizes it ' s Mako Tsunami , the top - ranked ocean duelist . ( In the Japanese version , Yugi says that Kajiki came in third in the national championships . ) He asks who they are , insisting he ' s not a " freaky fish guy , " as Joey says ( In the Japanese version , Jounouchi says Kajiki ' s a drifter ) , even as an octopus crawls over the top of his head . Téa giggles , telling him he ' s got company , and he snatches the creature off his head and flings it into the sea , to Joey and Tristan ' s dismay , they ' d have liked to eat it . Mako can ' t believe those two are here as duelists . Yugi introduces himself , apologizing about Mako ' s fish , and Mako is delighted to meet the duelist who beat Seto Kaiba . He says it will be his honor to duel Yugi , and invites him and his friends to join him for a meal , which they happily do . But as they enjoy the fish , Mako smiles to himself . When they ' re finished , the happy crew ask Mako how he learned to cook like that . Mako tells them that he ' s had to fend for himself since he was a tadpole . His father taught him how to fish and cook . Yugi asks him what brings him to the competition , and he says that his dream is to win enough money to buy his own boat . ( In the Japanese version , Kajiki says once he wins the competition and buys himself a great boat , he ' ll catch fish like they ' ve never seen before . Yugi asks if he ' s really going to buy a boat , and he says he ' d like to get one of the newer models , so he can go back out to sea . Then every day will be big - catch day . ) They thank him for the meal , and start to leave , but he stops them by throwing his harpoon to land at a frightened Yugi ' s feet . He treated them to dinner , he says , now perhaps they ' ll honor him with a Duel . Joey thinks he ' s nuts . Mako says he ' s not , but he is an expert fisherman , and they ' ve taken his bait . He laid out his fish and lured these three right in . But he never expected to catch Yugi Mutou . Joey tells Yugi to forget this crazy chicken of the sea . And Tristan wonders if they can ' t just give the guy back a few fish . Mako says a Duel against Yugi would be a true test . Yugi ' s Puzzle activates , and Yami Yugi takes over . ( By now , in the Japanese version , they don ' t show the whole transformation when Yugi ' s puzzle goes off and the spirit comes out to Duel — all we see is Yami Yugi appearing in a cone of light . But the US version continues to add back the entire sequence of the puzzle turning , Yugi ' s hair flying up , the magic circle spinning under a cone of light , and then Yami appearing . ) Yugi accepts Mako ' s challenge . A Dueling arena rises up out of the sea , its playing field half land , half sea . They each wager two stars , and Mako thinks that finally he ' s met an adversary of real merit . Mako ' s monster remain hidden under water . Yugi ' s a bit thrown by having to duel against monsters he can ' t see . How can he know which monster to play when he can ' t see what he ' s fighting ? When Yugi plays " Full Moon " to power up " Silver Fang " , the Full Moon also causes the sea levels to rise . Mako continues to flood the field with the help of " Kairyu - Shin " . All men give pause before the savage power of the mighty ocean , Mako says . Even the greatest of fishermen . Yugi realizes Mako is talking of his father , and Mako says his father was a great fisherman , who taught him his love of the sea — until one day , the sea took him . ( In the Japanese version , Kajiki says that now the fear of the sea is written all over Yugi ' s face , just as it once was on his . Yugi asks what he means , and Kajiki says his father was the best fisherman in their village , but he lost him to the sea . ) Mako says he used to love going out to sea with his father , just the two of them on their boat . In flashback , Mako ' s father looks out over the waves and tells little Mako there ' s a storm blowing in . Suddenly , Mako recounts , the calm , friendly sea turned into a raging maelstrom , pitching their boat as if it were a toy . Mako ' s father tied him to the mast to keep him on the boat , but a huge wave swept his father out to sea . Mako is convinced his father is still alive , and is determined to buy a boat so he can search the Seven Seas until he finds him . ( In the Japanese version , Kajiki says that after the storm , the boat had drifted back to shore , but his father was nowhere to be seen . Now , he has to take his father ' s place , and battle against the sea himself . Someday , he ' ll become the country ' s greatest fisherman , one who won ' t lose to any seas , no matter how rough . But he needs a boat for that — that ' s why he can ' t let himself lose . ) Yugi understands Mako ' s determination , and now Joey and the others also see that Mako is fighting for someone other than himself . Yugi eventually gets his " Giant Soldier of Stone " to attack the Moon . Once the Moon is destroyed , the field is dried up and Yugi uses " Curse of Dragon " combined with " Burning Land " to destroy Mako ' s monsters and reduce his Life Points to 0 , winning the Duel . Mako ' s disappointed , but accepts defeat gracefully , telling Yugi that destroying his own Moon was a brilliant and unexpected move . He laughs , saying it was a grand Duel , and Yugi tells him the Duel was not easily won . Mako ' s down to one Star Chip , but he intends to start over again . He and Yugi shake hands and part as friends , then Mako leaps back into the sea and swims away to catch some more fish . Tristan says he wishes Mako would bring them some more fish , but Yugi points out they ' d have to Duel him again . The four friends walk away together . Featured Duel : Yami Yugi vs . Mako Tsunami .
