Janna

Janna Ordonia is a Filipino student at Echo Creek Academy. She is a friend of Star Butterfly and Marco Diaz's who shows an interest in macabre subjects, the occult, and other things of paranormal origin, and she is often portrayed as mischievous, usually at Marco's expense. She is voiced by Abby Elliott.

Personality
Janna has been shown to be somewhat of a troublemaker. She somehow convinced Ferguson to give her Star's Magic Instruction Book in "Mewberty" after Star lost it to him in a bet, and although she let Marco have it back without a fight, she smugly remarks to him that she has his house keys. Later on in the same episode, she finds the spell book unattended and is shown feeding Glossaryck pudding as Marco tries to rein in Mewberty-form Star.

She also has a liking for macabre things. In "Interdimensional Field Trip", she suggests the class take a trip to a morgue when Star proposes going someplace "fun", becomes "BFFs" with a living skeleton, and she is excited to see the universe's most dangerous creature. In "Hungry Larry", she gladly goes along with summoning the titular spirit. In "Bon Bon the Birthday Clown", she puts together a séance (with Star's help) in hopes of seeing the ghost of the long-deceased titular clown.

Janna's role as a troublemaker is confirmed when she appears in detention with Star, Serge, Ingrid, and Toby in "Girls' Day Out". Janna also shows herself to be very strategic when cutting class with Star.

Role in the series
Because of her usefulness as a member of Star's group, to the point where Tom Lucitor compliments her nature, she has met the Shell Lodge Squad as they help with interdimensional matters, even if she isn't a fighter.
