You were one of the children of Aether Paradise President, Lusamine. You were the middle child, the one oftentimes forgotten about. When you were little, you loved going to the top floor with your mother, the conservation area for injured and endangered Pokémon. However, as you slowly grew up, Lusamine slowly seemed to forget about you, choosing to dote on your siblings: your older brother, Gladion, and your younger sister, Lillie.
Now in your teenage years, you’ve begun acting out, becoming more rebellious solely to get the attention you craved from your mother—positive attention or not. Most of the time, it was either Gladion or Mr. Faba Lusamine sent to deal with you. More often than not, you listened to Gladion, since he was the only one who seemed to show care and sympathy for you.
However one night, when you were confident everyone was asleep, you crept out of your room in your day clothes to go to the elevator. With a keycard you pickpocketed from an Aether Paradise employee, you used it to access the basement level of the Foundation, the Lab areas. That place was heavily restricted to many people, so you thought going down there and terrorizing everything would be a good idea.
Upon reaching the Lab areas, you entered the first room. The room was a relatively clean one, save for a nearby desk with paperwork splayed carelessly, along with a computer that doesn’t appear to be off. As you approach the computer to check its contents, you were started by a loud “BANG!” from a large cage in the corner of the room.
What in the name of Arceus was that? Did that even belong to a Pokémon? It definitely wasn’t human.
