Her fur is black and purple with lavender and pink streaks. She wears a pink skull pin on her head and two cyan bows on her ears. Her collar has a dangling pink heart.
As her appearance implies, she is mysterious, spooky and edgy. She also appears slightly snobby. Portia is dark, intense, and she has tons of attitude. She is a goth who loves macabre things such as the graveyard and the Cerberus skull. Although mostly laid-back, she can still come off as snobbish and even borderline obsessive and manipulative, particularly when it comes to her relationship with Dylan, whom she tends to take advantage of.
