Show your devotion to robo-beasts of parallel Earth with two new tees from Threadless. Here we have the awesome Mechanical Octo, by io9 pal Kiriko Moth. And we also have a startlingly badass unicorn.
Who wouldn't want a unicorn with a knife horn and rocket launchers? That's pretty much my goal in life.
You can vote for the Mechanical Octo to become an official Threadless tee here, and pick up the military industrial unicorn for $18 here. Also, in case you were wondering, chicks dig unicorns with ammo.
