Power Rangers: Once and Always

On one version of Earth in the year 1993, five teenagers with attitude were chosen by the being known as Zordon to fight the villain known as Rita Replusa. Those teenagers were Jason Scott, Kimberly Hart, Zack Taylor, Billy Cranston, and Trini Kwan. Not long after, another teenager named Tommy Oliver joined. After their time as Rangers ended, many other Ranger teams were formed and fought for good. Trini eventually had a daughter named Minh Kwan, and Tommy with another Ranger named Katherine Hilliard had a son named JJ Oliver. But in 2022, Rita Replusa returned and Trini was killed. A year later, Minh took up the mantle of the Yellow Ranger and helped Billy, Zack, Katherine, as well as another Ranger named Rocky DeSantos stop her. Minh followed in her mother's footsteps and became the new Mighty Morphin' Yellow Ranger, while JJ joined SPD.

On another Earth, one very different, most of the world's population had superpowers called quirks. Zordon instead recruited Jason, Kimberly, Zack, Billy, and Trini in 2093, Tommy also joined shortly afterwards, since in this they were all born a hundred years later. Just like in the other universe, eventually they stepped down and other Ranger teams rose up. But here, Trini had a daughter with Billy named Sasha Kwan-Cranston, and Tommy had a son with Kimberly named James Oliver. But when Sasha was little, her mother died in a car accident. Eventually, Tommy gave his Green Ranger powers to a young man who he and Kimberly would soon take in named Izuku Yagi. Kimberly have her Pink Ranger powers to a girl named Ochako Uraraka. Jason gave his Red Ranger powers to a young man named Eijiro Kirishima. Billy gave his Blue Ranger powers to a young man named Tenya Iida. Zack gave his Black Ranger powers to a young man named Fumikage Tokoyami. Tommy gave his White Ranger powers to James. And Trini's Yellow Ranger powers were given to Sasha, not unlike Minh.

But then, in 2024 of the first Earth, and 2124 of the second, something happened.
