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.
Nova first appears in the story "Cleopatra's Pleasure Tour", where she is summoned into the present world while on a mission for the Future Rebel Army. Unsure of what happened, she investigates the nearby area, confused to where the enemies are. El Dorado appears and asks for peace, but because she is intent on finding the enemy, is forced to battle her.
She easily overpowers El Dorado and prepares to finish him off, but Vita arrives and orders her to stop. Nova recognizes Vita and stops, before being told to follow her, which she does. Outside the town, Nova introduces herself to Vita and begin to tell their backstories. Nova admits that she dislikes the human Vita, but was surprised when she saw her as a cyborg. She also admits that she is jealous that Vita has friends and family to protect. Sharing some unknown bond, she offers Vita the Union as a gift.
When Cleopatra arrives to investigate a power surge, she defeats Vita and approaches Nova and the Union. After a short clash, Nova prepares to go all-out when the Big Gate forces her back to the future alongside the Union.
