Iczer-2

Iczer-2 is a thoroughly evil gynoid created by Big Gold specifically to counter Iczer-1. She pilots Iczer-Sigma, and refers to Iczer-1 as "big sister". Her powers and weapons are identical to Iczer-1 save for not being able to travel in time; the Iczer Sigma is capable of controlling floating mines and can summon a very strong energy beam from the sky. In the sequel "Iczer Reborn" after Atros' repeated failures to kill Iczer-3 and destroy the Queen Fuji, Neos Gold starts to realize that the only one capable of defeating Iczer-3 is another Iczer gynoid, and resurrects Iczer-2 to that end. However, Iczer-2 refuses to submit to Neos' will, stating her only desire is to fight Iczer-1.

In response, Neos Gold tells her that by killing Iczer-3, Iczer-1 is sure to return to avenge her little sister's death. When Iczer-2 and Iczer-3 finally meet in battle, Iczer-3 is quickly outclassed by the more experienced Iczer-2, who seems to only be toying with her. She tells Iczer-3 the reason the Iczers were created is to fight, a philosophy that Iczer-3 rejects. Later, after a fully rejuvenated Iczer-1 returns to Earth to aid Iczer-3, Iczer-2 gets her shot at revenge against her elder sister. Though she fights with all her strength, Iczer-2 is once again defeated by Iczer-1, who decides to spare her life in the end, saying she will not let another sister fall in battle.

Iczer-2 then aids her sisters in the final defeat of Neos Gold, though it is Iczer-3 who delivers the finishing blow. At series' end, Iczer-2 leaves Earth to wander the Universe, thinking perhaps they will all meet again. Her current location is unknown.
