Nova (Metal Slug Attack)

A cybernetic clone of Vita, improved with the advanced technology of the Future Rebel Army. Although Vita herself is still alive in Nova's time, she's lost all mobility and has been confined within a life-support system. It's unknown as to whether Nova is autonomous or remotely controlled by Vita, but Vita does stick close to her "sister" in battle and will appear from underground (next to a single clone) should her twin's side achieve victory.

Compared with the original, Nova's power and durability are greatly improved, even though her basic movement patterns are relatively unchanged, while still being visually distinct. Just like the original, she shuffles across the battlefield slowly, suddenly leaping forwards when an enemy comes into range in order to deliver devastating combos. She no longer appears to be able to fly, however, and her two explosive eye-lasers don't have quite the same range. Her voice is of a slightly higher pitch than that of the original.

Similarly to Vita, should Nova be critically damaged, she goes on a self-destruct protocol to take any enemies with her, while revealing some of Vita's old wounds in the process.

Although Nova initially disliked Vita at first, she soon bonded with her original host in the present timeline after seeing that she was not what she expected to be. Nova soon came to realize that she was Vita's only hope, and as such, devoted her efforts to ensure Vita's happiness.
