Ruby was born in Hoenn, where she met her trainer. Her trainer had a whole party of Pokemon to use, but Ruby was the team leader, always coming out first and tearing through opponents with a smile on her face. Ruby always loved the thrill of battle, loved the feeling of winning most of all. Watching her trainer exchange a firm handshake after a battle well fought was the sign of a job well done.

Her and her trainer never stayed in one place for long, both of them having a similar craving for thrill and adventure. Once they traveled every bit of Hoenn they had access to, they left for Sinnoh, where her trainer was originally from. Kalos was next, and then Johto, and Kanto. Ruby found Kanto to be especially interesting, especially the island they took a tour on where she was introduced to the pinkan berry, which was said to only grow in this one location. She was instantly enamored by the taste, sweet like nature's perfect candy. Pokemon who eat the pinkan berry are known to turn pink, and Ruby was no exception. Her white fur was stained pink and her markings were a striking magenta, and neither her nor her trainer really seemed to care.

It was only part way through their exploration of Unova that her trainer started to get worried, when the color still hadn't faded from Ruby's pelt. It turned out she had been hoarding the pinkan berries in secret, ordering them overseas using her trainer's money online. They had a stern talk with her, which ended with a pout and a small tantrum, but Ruby seemed fine up until the end of their Unovan adventure. Ruby had been more agitated during their fight with the elite four, unlike her normal good sportsmanship while battling. Her attacks were more savage, her smack talk cutting a little too deep. While busy planning their next trip with Alola on their minds, Ruby snuck behind her trainer's back to buy more berries for herself. She got caught and stopped, but her trainer was betrayed. They started their trip to Alola, but adventuring wasn't as fun anymore. Not when your partner pokemon was always sneaking glares at you, and your trainer felt like they couldn't trust you alone. They decided Ruby needed a place to stay, where she would be away from the temptation, and out of the chaos.

It's been some time since Ruby was first sent to the Aether Foundation. She's still not quite used to it, but things are better. Her trainer even sent her a pinkan berry candle in the mail during her first few months, and it does a great job at keeping her calm without giving in to the addiction. Her fur has begun returning to it's normal shade, though her slight pink tint may stick around forever.
