Kari

{One of Dark's ideas }

Kari Thunder is the first child of Dark and Storm. Her eyes have three times the power of Dark's eyes, though they can only affect the world around her. Her natural ability is her eyes' additional power, beyond what she would otherwise have. Kari's blood is acidic to the point that nothing can withstand it, serving as a deterrent to wounding her as well as a good defense and offense.

In the Failed Reset Era's climax battle, Kari did little fighting, attempting instead to get the others out before Dark would use his final attack.

Kari is currently in possession of Dark's ultimate self's right eye, and is in the higher Scale, beyond the buffer the others went to. She is accompanied by Akira, one of the twins who Dark and Storm adopted.

The following was never implemented, as it was intended to happen during the Higher Scale Era, which itself was never implemented:

While there, in an effort to survive and attack by an Eater, she integrated Dark's eye into her own, giving her all of his eye abilities at her eyes' level of power. Unfortunately, the drain on this in the Scale became great enough that she can only have her right eye active for 22 seconds, while her base left eye can be used for 7 minutes before strain becomes too much.
