He was brought back to life after Goodwin ' s defeat . He was last seen in Crash Town , where Kalin attempted suicide by Dueling in order to atone for his wrongdoing , only to be forgiven for them by his former teammates , Yusei Fudo , Jack Atlas and Crow Hogan . He later stayed behind to help rebuild the town along with West and Nico , which was later renamed Satisfaction Town to cherish his team ' s honor . Design . Personality . Originally , Kalin started as a cheerful and good person , who looked out for his teammates and gave hope to them . But after his team conquered the entire city of Satellite , Kalin became obsessed with protecting what they worked so hard to obtain , and grew paranoid into believing that any Duel Gang s not under his control were a threat to the order they had brought . This caused him to begin Dueling people recklessly including kids , which harmed them in the process , and which eventually lead him to challenge the city ' s security , which caused his downfall . Kalin was captured by them and sent to prison to die and blamed Yusei for his betrayal and capture . As a Dark Signer , his personality had become even more crazed , which resulted in him bursting out in insane laughter at his opponents ' and enemies ' pain and misery . He also showed great hatred towards his former teammates , Jack Atlas , Crow Hogan , and especially Yusei Fudo , to whom he would often call a traitor and exclaimed " You betrayed me ! " After his death and revival , he came to realize that all his pain had come from his own mistakes , and made him regret what he had done in the past . Depressed and guilty , he ventured out to Crash Town and looked for a place to die , and was uncaring of what befell him . His method of Dueling showed that as his monster ' s effects acted like Russian Roulette . But after seeing Yusei and the kids , West and Nico attempting to save him , Kalin regained his self - worth and kindness as he vowed to protect them and all the citizens of Crash Town . Abilities . When a Dark Signer , Kalin was able to project his " Earthbound Immortal " into fog as a purple image , which also caused Yusei ' s mark to react . Even after being revived as a normal person again , he was still capable of inflicting real damage to an extent , as the attack of his " Infernity Doom Slinger " was strong enough to fully knock out Lotten . Biography . History . Kalin was once the leader of The Enforcers ( Team Satisfaction in the original version ) , which consisted of himself , Yusei Fudo , Crow Hogan and Jack Atlas . He met with the trio for the first time when he approached them with the idea for the Team . He fought for his own ideals and unique sense of unity and gave his team a true glimpse of hope under the despairing circumstances of the Satellite . The team managed to conquer all the team areas in the Satellite by beating the other Duel Gang s . During the face - off with the final gang , one of them almost killed Yusei by pushing him off the roof , but Kalin saved him . After conquering all the zones in Satellite , Kalin got into a fight with a kid from Team Insect , something that prompted Crow and Jack to go against Kalin and leave the team . Later , when Sector Security began arresting Duelists in Satellite , Kalin decided to take action into his own hands and blew up a part of the Security base , and he seemed happy that he did it . At this point , Yusei left as well . The abandonment felt at the Enforcers ' dissolution caused Kalin to become obsessed with ruling Satellite forever and reuniting his group for their last Duel against Security . He was eventually pursued by Security until his former teammates came to his rescue . However , neither Crow , Jack or Yusei believed they could defeat Security , so Kalin confronted a Security guard on a Duel Runner and ended up driving through a bunch of crates , which severely injured the guard . Before he could finish him off , Yusei interfered and isolated him in a room . Yusei then decided to call himself the leader of the Enforcers in the hopes that they wouldn ' t arrest Kalin . But security found Kalin and arrested him for injuring a guard . One of the Security members had already figured out that Kalin was the leader and Yusei tried to convince that " he " was the Enforcer ' s leader ; Kalin saw Yusei trying to convince Security to let him go , and he mistakenly believed that Yusei had him purposely arrested . Kalin attempted to fight him , but was held back by Security and was arrested . In the Facility , Kalin was painfully imprinted with a criminal mark , and the prison guards constantly beat him up and intentionally withheld his food rations . Although he claimed that he could survive the abuse , his resistance was weakened when Security took his Deck , which was his most prized possession . After that , Kalin was seen in a cell , near death from starvation , when a voice spoke to him . It called itself the " Envoy of the Underworld " who came with a proposition : If Kalin had some sort of unfinished business , he could come back to complete it as a Dark Signer . Because of his grudge against Yusei and his wish to fight the last battle with Team Satisfaction , Kalin accepted , died of starvation and was reborn as a Dark Signer . At some point after that , he escaped prison and eventually joined up with the other 3 Dark Signers : Roman , Devack , and Misty . They were all under Roman ' s leadership . Dark Signers . Kalin was waiting for Yusei who had been accompanied by Crow , and as they both entered the B . A . D . area , Yusei and Crow were both shocked to see him . He jumped on his Duel Runner and created a shadow barrier in the process , which suddenly formed , and separated Crow and Yusei . The barrier began to take the shape of his mark , the Giant . Kalin then exclaimed that he would take down Yusei , as their Shadow Turbo Duel was about to begin . Before the Duel started , Jack appeared in a helicopter , Kalin exclaimed that the Enforcers were together again . The Duel began with Kalin gaining total control and him telling Yusei to suffer . Throughout the whole Duel , Kalin laughed hysterically when referencing their past together . Yusei pleaded with Kalin to stop , and reminded him how he had saved Yusei ' s life years ago . Yusei still didn ' t understand why Kalin hated him . Then after Kalin ' s direct attack , he remembered . Yusei had stopped Kalin from escaping arrest after he almost killed one of the Sector Security ' s squad members . Yusei Summoned " Stardust Dragon " , but Kalin countered by Summoning his " Earthbound Immortal " " Ccapac Apu " , which nearly ended the Duel . However , before he could claim victory , Yusei ' s Duel Runner malfunctioned , and critically injured Yusei . Upon seeing this , Kalin laughed and ended the Duel without a victory , and told Yusei to suffer the same pain that he had endured . When he returned to the headquarters of the Dark Signers , Roman Goodwin asked him why he did not kill Yusei . Kalin replied that he would do so if all Dark Signers were present . He also said that he would let Yusei live in fear after he witnessed the power of his Earthbound Immortal . He was present along with the rest of the Dark Signers when they all confronted the Signers right after Yusei ' s and Roman ' s first Duel concluded . He tried to degrade Yusei by calling him weak , however Yusei ' s opposite reaction to that comment surprised him . After Yusei finally arrived at the Giant tower , he and Kalin began their rematch and told him that this would be the Enforcers ' last Duel . He continued to use his Handless Combo strategy . He eventually Summoned his Dark Synchro Monster " One Hundred - Eyed Dragon " once again and assaulted Yusei with its effect . After Yusei destroyed it , Kalin revealed to him the horrible incidents that occurred to him while being a prisoner before he became a Dark Signer . As Kalin said to Yusei that by accepting his fate , he could return to show Yusei the fear that he had felt at the time . Intending to do this through his " Earthbound Immortal " card , he then Summoned " Ccapac Apu " once again , and tried to finally defeat Yusei with it . However , as Yusei managed to fend off the Immortal ' s assault , the Immortal itself began to trash the ground where the Duel was taking place . As Kalin began to have some difficulties with this , Yusei extended his hand to offer his help , which symbolized the occasion where Kalin risked his life to save Yusei . However , Kalin rejected it , and stated that it was too late and that it was completely pointless . After this , Yusei Summoned " Majestic Star Dragon " , and it ultimately took down " Ccapac Apu " . By this , Kalin lost , and in the end , not only did he make peace with Yusei , but also reveals to him that he had another purpose besides revenge when he transformed into a Dark Signer ; Kalin also wanted to carry out the Enforcers ' Last Duel . Following that , Kalin finally turned to dust . Kalin was the third Dark Signer to be defeated . When Rex Goodwin was defeated in the final battle , and the King of the Netherworld was destroyed , Kalin was restored to life , along with the other Dark Signers except for Roman and Goodwin himself . After these events , he was gone on a trip , according to Luna . Crash Town . Following the events of the Dark Signers , Kalin resided in a town that was ruled by Dueling . His appearance had gradually changed over the course of time ; his hair was much longer than before and he wore a trench coat . He also carried around a harmonica around his neck ( which he often played ) and his personality showed no emotion ; when he did show any emotion , it was of sadness , concern , or pity . He followed the gang leader Radley , and a bunch of Duelists that dominated part of Crash Town . Barbara told Yusei that Kalin had come to this town to die . Kalin said that he had forgotten the meaning of words such as satisfaction . He Dueled one of the members of another gang led by Malcolm and ultimately won against his opponent . After the Duel , Yusei tried to talk to him , but he gave no reply as he rode off with Radley ' s gang . After the Duel Kalin was in the gang bar , but left so he could be alone . Kalin still had memories of the time when he was a Dark Signer ( how this occurred was unknown ; it was possible that he remembered because he became a Dark Signer willingly , like Rex and Roman Goodwin , and that unwilling transformations like Carly ' s resulted in memory loss ) . Being left with the guilt from what he had done to hurt his friends , he struggled to end his life through the only thing that once mattered to him : Dueling . The next day Kalin challenged Yusei and revealed his intentions , and pleaded with him to defeat him so that he could die in the mountain . Kalin fought hard , and refused to simply throw the Duel , and even resorted to Summon his " Infernity Doom Dragon " . Ultimately , however , he was defeated by " Stardust Dragon " again . After the Duel , Yusei and Kalin were double - crossed by Barbara , who was secretly a member of Malcolm ' s gang . They were apprehended by the undertakers and taken to the mountain along with Radley after losing to Lawton , Malcolm ' s brother . Kalin went to work with no second thought ; even Yusei couldn ' t convince him to escape otherwise . Yusei then punched him in the stomach and left him unconscious . He took Kalin and escaped , and as they did , they ran into Nico and West . Soon after , Lawton and Malcolm ' s gang members found them , Yusei went and Turbo Dueled Lawton , while Kalin was running away with Nico and West in a miner cart from Malcolm ' s gang members . Kalin managed to steal a Duel Runner from one of the members of Malcolm ' s gang , and used it to get to the Duel between Lawton and Yusei . In an attempt to get rid of them , Lawton threw dynamite at them , which caused the mine to collapse and left Kalin and Yusei in a crevice , while West and Nico were taken as hostages by Lawton . After visiting the graves of those who went to the mountain , Kalin vowed to fight for those either still working in the mountain or had lost their lives because of it and to save West and Nico , and called himself a " Death God " . Returning to Crash Town , to the shock of Lawton and the others , he and Yusei engaged in a 2 vs 1 Duel with Lawton , to free the town from his horrid rule . Though their Duel was coming to an end , Lawton ' s men interrupted and proceeded to stop Yusei and Kalin . But the members had a change of heart and decided to hold back . Lawton and Barbara attempted to make a final getaway but were stopped by Crow and Jack . In one last attempt , Lawton detonated the explosives in the city , which created a diversion . Kalin gave chase on Yusei ' s Duel Runner and caught him in order to finish his last turn . Lawton , knowing his top card was a spell card that would render Kalin ' s " Infernity Doom Slinger " useless , agreed to finish the Duel . But Kalin used the effect of " Infernity Climber " to draw this card instead of his spell card , using the effect of " Infernity Doom Slinger " , and finished off Lawton ( In the dub , Kalin , after catching up to Lawton , restrains him until Sector Security arrived as Kalin believed he didn ' t deserve to end the Duel properly for being a coward ) . After that , Kalin stayed in town to watch over its reconstruction , and to watch over the kids , West and Nico . In honor of his team , he renamed Crash Town , Satisfaction Town . Ark Cradle . In episode 150 , he was cheering on Yusei . Two episodes later , Kalin reappeared and was seen being defeated by Jack in Satisfaction Town as Jack was self - training himself to once again regain his crown as the King of Turbo Duels . Kalin told Jack that he had become a lot stronger since the days of the Enforcers but he was still not satisfied , with Jack agreeing . Manga biography . Kalin appeared in the " Yu - Gi - Oh ! 5D ' s " manga as an eliminator within the D1GP . Decks . Ground . Past . While the nature of this deck is unknown , Yusei noted that Kalin ' s main aspect of it was constantly keeping his hand full to keep his options open . Turbo . While being a Dark Signer , Kalin used an " Infernity " Turbo Deck centered around his " One Hundred - Eyed Dragon " . He used cards such as " Depth Amulet " and " Limit Impulse " to reduce his hand size while also filling his Graveyard with his " Infernity " monsters , which he then copied the effects of with his " One Hundred - Eyed Dragon " . If this strategy failed , Kalin used the effect of his " One Hundred - Eyed Dragon " to add his " Earthbound Immortal Ccapac Apu " from his Deck to his hand , which he then easily Summoned through cards such as " Infernity Necromancer " and " Damage Translation " , also supporting it with cards like " Brilliant Shrine Art " and " Wicked Trample " to lock his opponent down and inflict large amounts of damage .
