Calamity EVO: Generator Anne
is a crossover between Amphibia and Generator Rex, where Anne and Marcy end up in Amphibia together, and Anne gains new powers when they stumble upon ancient ruins.
- Adaptation Expansion: In this story, we learn that the reason that Anne has so many random items in her bag when she went to Amphibia is that her mother made her clean her room, so she just shoved a bunk of stuff in there.
- Age Lift: Anne, Marcy, and Sasha are 16 in this story rather than 13.
- Crazy-Prepared: Marcy was carrying a portable chemistry kit, a portable geology kit, and some chemicals when she and Anne ended up in Amphibia.
- For Want Of A Nail: Marcy managed to stay with Anne because she grabbed Anne's arm moments before the Box was opened.
- Innocent Fanservice Girl: At one point Anne takes off her shirt due to the heat, not realizing that Marcy is very much flustered by the view.
- Oblivious to Love: Marcy has feelings for Anne, but Anne doesn't realize it, even when Marcy is blushing something fierce because Anne is only wearing a sports bra due to the heat.
- Painful Transformation: Anne and Marcy gaining their EVO powers while being experimented on is clearly not a pleasant experience.
