Samejima, Taiga

鮫島大牙

Taiga is a member of Team Shark Tooth, the team whose leader, Taiga's brother Gabu, challenged Sho to a battle. During the fight, he, along with the rest of Team Shark Tooth as well as Sho Yamato, Makoto Shido, and Kakeru Sakamaki, was whisked away into the mysterious X-Zone. In the X-Zone, he was ordered by Gabu to hire people within the X-Zone outside of X City to stop Sho and company from reaching X City, offering big rewards such as the position of second in command. He later went to stop Sho himself when all else had failed, and ended up failing as well when he was attacked by bats in the cave where he was racing Sho. After Gabu found out about Taiga's loss, he became angry with him and gave all his duties to Koei. He participated in the Idaten Tournament under Gabu's orders but lost in the quarter-finals to Arthur. In the X-Tower, Gabu accused Taiga of purposely losing so that Sho could win the tournament and fired him from Team ST. He was later found by Yuki and Sho and Co. while watching the match between Koei and Arthur. When Kiku, Koei's sister, was kidnapped, Taiga joined forces with Sho and company to rescue Kiku. When Kiku's rescue was a success, Taiga suspected that Gabu would steal the 10 Gold Emblems and battled Gabu to stop him. Even though the battle was not shown, Taiga was defeated and beaten quite badly and was even chained to a statue for days. After he was freed, Taiga knocked out and fainted, proving that he was exhausted. After the battle between Gabu and Sho, Taiga was one of the few to search for Gabu under the X Tower debris, from there, they were transported back to their world.
Taiga also aids in the search of Kyoichi Shido, who was left behind in the X-Zone. When Team X struck, Taiga stayed in X City to protect the area. He now shares the man-made X-Zone with Sho and company and the rest of Team Shark Tooth.
