Obtained as an egg and hatched as she just began her journey. Evolved into Low Key form Toxtricity and became the reason for her secondary poison typing.
Caught while training in the Kalos region as a Feebas. Research had led to her wanting to train it to be the Milotic it is today. Shiny was just an added bonus!
Found being bullied by other Mareanie and Toxapex before being left behind as they went off to hunt Corsola. Caught and nursed it back to health. Only unevolved pokemon on party.
Literally walked into it somehow. How? Don't ask me. Or her. She has no idea and will never admit to being that unaware of her surroundings. Garbador followed her until she decided to catch it.
Caught on a whim. Accidentally the strongest member of her team at the team, one shotting a few battles immediately upon first attack. Saoirse thought it was a fluke at first. Turned out to not be the case.
(As Sword/Shield protag) Caught as game progresses. Turns out Zamazenta was literally a giant hyper puppy in personality for her. Got the name by behavior.
