Porsha is a tall Arctic-gray wolf with yellow eyes and bluish-grey and white fur. She wears purple sunglasses, a dark blue jacket with multicolored accents, yellow trousers, and a blue top with Clay Calloway's face on the front.
Porsha appears to be quite adventurous, as she is seen volunteering to perform a dangerous stunt in Rosita's place. She is also said to be rather spoiled and Halsey has even called her “awful”. She's a drama-queen and can jump to her own conclusions, leading to misunderstandings.
However, despite her spoiled nature, she does have some empathy and consideration for others.
In the end, she mustered up the courage to stand up to her father during the performance, so she can follow her dreams.
She is first introduced in the film by her father during the studio tour, the latter declaring that she is a huge Clay Calloway fan, even wearing a vintage t-shirt with his face. Following Rosita's sudden dizziness as she was about to do a harness stunt, Porsha settles onto the platform with the urge to try the jump. Buster Moon objects to this, so Porsha complains to Jimmy, automatically giving her the green light to jump without hesitation. Already gleefully dabbling in the sensation, Porsha claims everything goes like in her dream last night where everyone in the studio was there and Buster had asked her to sing for him. She then sings "Girl on Fire" and once back downstairs, she insists that Rosita is too scared to play the main role and claims it herself. Buster still objects, but Crystal "convinces him" to let Porsha be the star of "Out of This World".
Now the main character, Porsha turns out to be a terrible actress during her first rehearsal, which Buster doesn't have the courage to tell her. Coming back later from shopping, Porsha is surprised to see Miss Crawly at the helm, while Buster left with Ash to recruit Calloway. As preparations for "Out of This World" soon come to an end, Porsha's acting has not progressed. Realizing this, Buster summons Porsha to his office where he explains that although she is exceptional, he deems it best for Rosita to reprise her role. Porsha absurdly interprets this as dismissal and angrily walks out of the office with the intention of telling her father about it, just to believe that everyone hates her when they look at her incredulously. Buster doesn't have time to clear up the misunderstanding as Porsha slams the studio door.
Porsha is then seen in Crystal's office sobbing as her father is only outraged by the image that his daughter being "fired" can cause him, even ordering Porsha to stop crying because she has embarrassed him and has her escorted home by one of his bodyguards. She continues to mourn in her bedroom until Miss Crawly comes to recruit her to continue the prematurely compromised show. Warmly greeted by the group, Porsha admits her overreacting earlier while warning that they are not safe from her father, although Johnny finds a solution to this problem.
When "Out of This World" is presented clandestinely to the crowd, Porsha dressed as a six-armed green alien now takes the central role of the second musical performance. Before entering the scene, Buster encourages the young wolf to show the world what she is truly worth. Porsha passionately sings and dances "Could Have Been Me" and when an angry Crystal interrupting backstage orders her to get off the stage, she finally stands up to him as she continues her graceful performance with the tarsier dancers and finishes under the cheers from the crowd, much to the joy of the female wolf. Soon after, she helplessly witnesses her father's attempt to kill Buster by throwing him from above, but the koala is saved by Rosita. Porsha also watches "Break Free" sung by Rosita and Gunther and the final "I Still Haven't Found What I'm Looking For" sung by Ash and Calloway. The gang then appear on stage and get praised by the audience, but leave when Crystal appears on stage and obnoxiously attempts to take all the credit for himself. The gang ditches him, leaving the audience to do nothing but shun him. Suki then ordered the police officers to arrest Crystal for his attempt to assassinate Buster during the show.
With the show finally over and successful, the gang begins the journey back to Calatonia when suddenly, Suki stops their bus to tell them that the Majestic Place wants to produce their show. Once Calloway agrees to continue, everyone else also accepts without hesitation. On the big night, Porsha and the others receive encouragement from everyone shortly before the start of the new "Out of This World".
