Iron Tager, designate TR-0009 (Red Devil), is a playable character and one of the supporting protagonists in the BlazBlue series. He returns as a playable character in BlazBlue Cross Tag Battle.
TR-0009 "Iron" Tager was once the leader of Bullet’s mercenary group who got mortally injured on a mission by Azrael; he was rescued by a female Beastkin scientist from Sector Seven named Kokonoe who modified and healed him with cybernetic implants and demon genes. Since then, he has become Kokonoe's main field operative, performing missions to assist his new master on her scientific works. However, he tried to keep his existence of being alive a secret from Bullet, telling Kokonoe not to reveal to his female subordinate about this.
Tager is one of the designated "slow grappler" in the game, capable of devastating close range attacks and grapple moves at the cost of his mobility. To compensate for that, his unique ability "Voltic Battler" uses his cyborg enhancements to empower his strikes with electricity and magnetizes his foes with them, allowing him to forcefully attract his opponents into his attack range.
