Boom-Boom Bear

Boom-Boom Bear is a childhood fixture of mine who came about from the need to have a means of defense at all times, when I was a child. People don't want children to have weapons, so it couldn't be anything overt, but I wanted to take advantage of how people assume that children are harmless.
So I made one of the ubiquitous stuffed animals into a deadly weapon. Yay me.

B3

I enjoyed plushy toys as a child. I think most of us do at that age, and probably for long after society deems it reasonable. It's not unreasonable for a six year old to want one, or for people to assume that they want one. My foster-parents-slash-minions were two such people. They gave me a teddy bear when they first took care of me, making just such an assumption.
Unfortunately for them, I was delighted by this bear and immediately sought to upgrade it to something "useful." My intelligence was newly enhanced and everything that had previously been a mystery bordering on magic now became a means by which I could actually alter the world around me. What person hasn't wanted to effect change on their circumstances? The more I tried, the faster I learned.
I adored Boom-Boom Bear (hereafter called B3) and so my modifications were simple, so he wouldn't be harmed. A simple power core at his heart, with an explosive charge in case of emergencies. Later on I added a sort of capsule that her shell and stuffing could be folded into, to protect them as the charge detonated. Inside out and scrambled she might be, but reparable and not blown into tiny bits.
She went with me everywhere I went, for those first few years. By the time of the Double January incident, I had pretty well weaned myself of the bear, but for a while she was my backup weapon. I still have her somewhere, carefully stored away, the explosive charge still primed and ready to go, just in case.
