Weapon design is particularly fun. Especially the more technical ones- splattering all sorts of tecknologickal gobbledegook is a blast. One of my favourite (and actually practical) ideas thusofar is a Gatling gun with a bicycle superimposed on top.
True enough. To be used effectively would require immense (surhuman, really) strength in order to muscle those spikes through your victim- or wrench it away when it inevitably gets stuck.
Fortunately, the character happens to be not human, so he needn't worry about such pitiful setbacks of us mortals. So the hooks actually work to his advantage, relling in foes who try to escape, and tearing flesh a lot more brutally.
