Pennywise from It
Born performers and somebody who wants to be SEEN – here they are, typical Leos and typical Pennywise. The costume, the makeup, the hairstyle, the drama – every single thing should attract as much attention as possible. True Leos are never against individualism, creativity, and self-expression. As for Pennywise, it scares people transforming into their worst fears, impressing them to the most extent.
Alternative version: a self-confident Count Dracula.
