I was walking by our coffee table upstairs, and there was this big syringe on the table, and I just picked it up and was twirling it in my hands while I said goodnight to my family (the syringe was one of those big plastic ones for measuring water). while messing around with it, a sudden spark of inspiration had hit me with the force of a cinderblock against a small pastry. I had the image in my head of a character who had these syringes on his leg, and ho could take them out and quickly insert them into a cylinder thingie on his hip. the syringe would fill up instantly with some sort of liquid(probably either explosive or flammable), and he could throw it like a sort of Molotov cocktail.

the idea was too good to simply pass, so as soon as I had the chance, I started to play around with the idea, and eventually came up with the character sketch here!
