*Zeta is the leader of Eagle Island, but it is not known exactly how she became one. She is very demanding of her subordinates: for example, she ordered Glenn to speed up the process of eliminating mistakes, and because of mistakes can send them to the torture chamber, which happened to Steve and Glenn himself.

Probably, Zeta has a high level of intelligence. According to Mighty Eagle, "she was the smartest girl in school"; she also tells Glenn how to implement her idea to improve the Ice Balls.

The nature of Zeta is very cruel as she was preparing to bombard the neighboring Islands, using snow ice balls and ice balls filled with lava. However, Zeta was wanting the inhabitants of those Islands to decide to evacuate, so, they won't die. In response to her actions, Zeta responds to the captive Red and Silver that she has an "ice fragment instead of a heart". In the last moments, Zeta's personality sharply converts for the better.*
