red robot doodle

So I was just sitting here minding my own business making light conversation and then I picked up a red biro and while typing I came out with this little beastie. All the scribbly bits are blood.

 

I'm pretty sure I must've got this idea from somewhere but after a few searches for 'axe wielding robot' I can't see anything similar.

 

Can someone please tell me if I've ripped someone off accidentally or if I actually designed this gem? If I did I'm gonna be making some mad cool slaps ASAP
