Carbon Costume

Levi Ackerman (voiced by Hiroshi Kamiya and Matthew Mercer) is a main character in the anime and manga series Attack on Titan.  Often referred to as Captain Levi, he is widely considered humanity’s strongest soldier, an especial feat given he is of such small stature.  Levi rarely shows emotion (unless it’s his proclivity for cleaning), which means he’s not close to many of his fellow Survey Corps members like Mikasa and Eren.
