I have reskinned a warforged fighter as a fine-tuned, yet horribly programmed killbot. That is to say, something that's really good at killing, but about as socially well-functioned as an ill-tempered squirrel. I am looking for additional ideas as to what his prime function is, or what his backstory was.
My current idea is that he was designed by a mad wizard who, during the final process of activating the killbot, woefully cursed his fate for "not having more time" as the adventurers raiding his lair killed him. And so, upon activation, this killbot seeks out any and all objects relating to time - watches, clocks, hourglasses, sundials, etc.
I would prefer something that is wacky, but not just flat out weird, so that it could be a point of comedy in a mostly serious world.
Thanks in advance.
