No. 13: Marceline (Adventure Time) – Best Cosplays

Marceline, the Vampire Queen, rocks an Axe-Bass and is over a thousand years old, making her one sexy, older vampire lady.

She starts off being a bit antagonistic toward Finn and Jake, but they become good buds as the series progresses, which is totally algebraic.

This is RedCappy as Marceline, seemingly floating in mid-air with the Axe-Bass, totally chill as can be. Marceline, why you gotta be so cool?
