How you meet: Ajax had gone to pick up a runaway who he'd traced to an abandoned building that housed drug addicts. He was walking through when you saw each other. Ajax smirked at you and you giggled back. He tossed you something he was eating and you picked it up, gnawing it. You found yourself utterly amazed by his presence and followed him around. Eventually he had to leave, finished with his task. When you saw him disappear, you started to cry. Ajax had almost left when he heard you crying. At first he ignored it and walked away. Then when he was in his car, his jaw twitched and he slammed on the breaks. He went out and grabbed you, then set the place on fire behind him.

Meeting the others: he keeps you around like a puppy, tossing his food bits at you to keep you fed. Some of his medical workers take turns actually taking care of you. You're pretty chill for the most part except when you want to see Ajax. He's the only one who gets you to sleep. Ajax of course didn't make the physical effort to put you to sleep, but he learned quickly that having a sleepless toddler was not fun. He just has to stay in the room, doing his own shit, and you're able to fall asleep.

Sickness: The scientists discover that you're deaf and want to "fix you", but Ajax doesn't let anyone touch you. He keeps telling them that you're too young. One time someone went behind his back and took you to one of the machines. You began crying, which you normally didn't do, so Ajax was quick to appear. The scientist who had taken you was themselves experimented on, excruciatingly. After that, no one took you for testing.

Danger: you lived in the warehouse so danger was everywhere. Ajax didn't stop you from getting hurt, letting you "build character". His workers moved you away from bigger threats though to escape Ajax's unaffected wrath. Some people who had more heart than Ajax, who had taken genuine interest in you, would take better care of you.

Bonding: Ajax deliberately spends time with you when he needs cheering up. You always seem on his side, agreeing with him. He starts teaching you sign language from a young age.

Kidnapped: a group of Yakuza visit the warehouse but leave with a broken deal. Soon after, you get abducted. Ajax is pissed to lose a property and goes out searching for you. Ironically, the Yakuza are in Deadpool's crosshairs as well, and Ajax reluctantly has to work with Deadpool to get you back.

Powers: When you were a teenager, you accused Ajax of not treating you when he could have. You either go behind his back or he angrily puts you through the system. You get the ability to hear things from a very, very long range, and you get a modified sonic scream. When you hear Ajax for the first time, you get emotional (but you don't show it).
