Adroit and Capsize Compeer

[Naught Important 434]

 

Adroit (The younger one) and Capsize (The older one with the robotic legs) are both brother and sister.
A certain mishap happened early on in Capsize's life, where his eyes could not refract light like normal, making everything seem upside-down. Capsize was having a very hard time adjusting to this, so his parents tried to find out a way to return his normal vision. A "Doctor" by the name of Overkill offered them a completely free solution to this problem. They didn't know what the doctor was going to do, but they trusted him to do whatever needed to be done. 
Once the doctor was finished, Capsize was brought into his workshop to receive the item that was said to help him with his vision. Capsize's parents expected it to be just a simple lens that could refract light like normal eyes could, but this was Dr. Overkill who they hired. Instead of just some glasses, the doctor amputated Capsize's legs (While he was unconscious, of course) and replaced them with a machine that left him hanging upside down. It was attached to his brain, so he could control the legs just like he would his normal legs. Adroit was with the parents when they first saw this, and she absolutely loved it. 
A few years later, the parents left. Adroit and Capsize didn't know why, but a long note was left behind stating that they were trusted enough to run the house. From then on, Capsize was practically Adroit's father.
