Nova
Nova is a character that first appeared on Metal Slug Attack as a Playable Unit, she's the final boss of Metal Slug 11

Profile
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.

Should Nova be destroyed, she'll reveal Vita's old ever-unhealing injuries before finally self-destructing.

Her voice is of a slightly higher pitch than that of the original.
