Iaian

How Iaian joined the Tourney
After the destruction of A-City, Iaian climbs out of the rubble only to see nothing standing in front of him but the Hero Association's Headquarters. He later saves a father and his son from being killed by Melzalgald after the father moves some rubble to get to his son. As he is standing there, the monster appears behind him and attempts to crush his head. Melzalgald only crushes his helmet, its occupant having moved away in time. He states that there was no way he would not have noticed its killing intent and proceeds to attack the monster. While dodging one of the monsters attacks, his left arm was torn off. Melzalgald began splitting itself into five different form, feeling hopeless of his situation, the monster is suddenly cut to pieces by Atomic Samurai and was ordered to stop bleeding by his master.

While the S-Class heroes are fighting the monster, Iaian advises to retreat and find another way to kill the monster, but his pleas were futile. During the fight he witnessed Bang being struck by Melzalgald attack and was surprised to see he was unharmed. After the monster was defeated the spaceship that was above them began to collapse and Iaian was helped carried by Atomic Samurai.

With the defeat of the Alien Conquerors, Iaian is handpicked to investigate a Romulan disturbance in the past. Upon his arrival, he learns he can communicate with certain animals, mainly Peaches, the wooly mammoth.
