Iaian is shown to be quick-tempered as witnessing the widespread destruction of A-city, an act he deems "unforgivable," enrages him. Also, upon being attacked by a mysterious alien, Iaian gives no quarter and responds immediately with an attack of his own.

Iaian makes his appearance only after saving a father and his son from being killed by Melzalgald after the father moves some rubble to get to his son in episode 10.
