Age of Apocalypse
In this alternate reality, Bova lived at Wundagore Mountain with Magneto and his X-Men. It was not revealed, but she most likely played a role in raising both of his children, Quicksilver and Scarlet Witch, just as in the regular Marvel 616 universe. Bova was the one who alerted Magneto to the arrival of Mystique and her young adoptive daughter, Rogue, who would later go on to marry Magneto. She was last seen mourning over the grave of Scarlet Witch.
Bova, as in the regular Marvel 616 universe, was a genetically advanced cow, thanks to the experimentation of the High Evolutionary.
