In The Secret of the Orb, she got angry because Ren and Marucho were fighting, when they were once friends. It made a dimensional twister, in which Mason got caught and Ren and Nurzak were forced to retreat.
In Code Eve, she reacted again transporting Dan, Drago, Barodius, and Dharak to her own dimension. There, she presented herself before them.
In Destiny Revealed, she explained the origin of the Bakugan and made an arena in a middle dimension, for Drago and Dharak to have their final battle. After Dan wins, Barodius and Dharak try to steal the Orb despite the loss but are transported to a dark-reversed dimension that she created as a prison for them. Code Eve then gives that power to Drago to evolve into Titanium Dragonoid, while she left Neathia by flying with the Orb itself.
After her departure from Neathia, Code Eve returned to New Vestroia where she actually lies within the Sacred Orb hidden in a cave.
In a deleted scene in Chaos Control, after Titanium Dragonoid uses Revolutional against Zenthon, she made a brief appearance to Dan and Drago. The same deleted scene also appears in a flashback in A Royale Pain. In Mind Search (her first appearance in the English dub), she was found by Dan, Drago and Wavern.
In Behind the Mask, Barodius and Dharak revealed that after being transferred to their prison with, their hatred and desire exposed to the Sacred Orb caused them to mutate into new unrecognizable forms that soon would be known as Mag Mel and Razenoid. After that, Mag Mel was able to manipulate his link with Dan in order to absorb all the Chaos Energy generated from all of his battles in Interspace and New Vestroia, so he can break free from his chains.

- Unlike the Perfect Core, Code Eve is able to speak.
- Only one Bakugan does not originate from Code Eve, Leonidas.
