Astra Cosmofly, birthname Star Butterfly, is a Mewman from an alternate timeline of Mewni. Her only visual difference from Star is that she inherited her mother's white hair. But she was cast out of her Mewni because her timeline turned out differently. In her timeline, Queen Moon didn't go to Queen Eclipsa for her Nameless Spell and only stripped Toffee of his Antithaumite essence. But because it wasn't as strong as the Nameless Spell, he regenerated from the damage and the monsters did not take her actions seriously, forcing her to retreat and look like a coward. Toffee came to be more moral in his pursuits without the Antithaumite to corrupt him, and his invasion was successful, destroying Butterfly Castle and exiling Mewmans into what would've been New M'onstrarus, leaving them to a mostly uncertain fate other than the expectation that they were nabbed by a hive of Wipers assigned to Mewmans. Mewni was no more and Toffee was declared a war hero. But Moon had her daughter sent to another dimension. She was meant to go into Mewni of the Main Timeline, but ended up being brought accidentally to the Main timeline of the Alternate UUniverses where she was raised by the Vaxies, space fairies that live in nebulas. Astra was raised in the Vacuo Nebula by Hellana, a mage in training who was xenophobic of cosmonauts since her family was killed by them. Astra grew up a magical space-faring adventurer just like Star. But when Star destroyed the Realm of Magic, it resulted in circumstances where she got into a heated debate with her mother about saving an astrophobic son of a famous cosmonaut, named Mako Sagan, and she accidentally used the last available magic to cast herself far away from home never to return with Mako upon learning she was adopted and being fed up with her strictness and xenophobia. She learns about Star Butterfly's actions on magic, and seeks revenge on her, blaming her for being lost. But when they almost kill each other, they are told the truth by the Time Councilor Kronunos, the replacement for Omnitraxus Prime in terms of time-related affairs, that they were both set up by Dark Starmapper, who caused Hellana's xenophobia and sucked Mako's starship into a black hole, just as a plan to take over space. Astra learns of the events of her home timeline and she and Star decide to take down Starmapper using a paradox that eliminates Hellana's xenophobia by preventing Starmapper's rival, the beamfly Mage Lyght, from ever leaving, thus preventing Hellena's death by cosmonaut. After reuniting Mako with his father and helping him recover his crew, Astra has since been on adventures with Mako, who is secretly in love with her, while also defeating Toffee and managing to alter the history of her own New Mewni, now called Astri, and make the Mewmans into an original race of space-faring greatly-powerful beings called Astamans, while making the Bestiarans muties (AUU multiform mutant-like trolls), while also altering her own history to being an equivalent of Star with a different family geneaology and history to the original, after admitting feeling shame for being one of infinite Star Butterflies of the timelines.


Coming soon...


Astra has much of the same abilities as Star, with a few exceptions. Raised as one of a space-faring fairy race has allowed her to not only breath in the vacuum of space, but she can fly at hyperspace. This allows her to fly as her own spaceship and even fly inside black holes and out. She also has her own array of magic spells that she can use without a wand. Many of them are similar to Star's trademark spells.
