Allen Wrench

"Help, I need tungsten to live! Tuuungsten!"

- Alan Wrench

Alan Wrench is a metallic-based lifeform who was found in a meteor that crash-landed on planet Earth. He currently works in a Swedish furniture store in Springfield. Virtually nothing is known about this alien's homeworld and biology, except that it has a strong biological need for tungsten.

Behind the scenes
In real life, there are some species of bacteria that do require tungsten to live, which makes this metal the heaviest chemical element used by living organisms.
