Stalyan

Stalyan is an antagonist in Rapunzel's Tangled Adventure. She is Eugene's ex-fiancée and the Baron's daughter.

Background
Stalyan resides in the city of Vardaros, at her father's castle. She follows in the Baron's footsteps and becomes a successful thief, herself. At some point, she would meet fellow thieves, Flynn Rider and Lance Strongbow, when they allied with her father. Stalyan and Flynn formed a partnership that eventually developed into a romantic relationship. The two later became engaged to be married, but Flynn notoriously left Stalyan at the altar. Ever since Flynn's departure, ending their romantic relationship and engagement, Stalyan felt immensely betrayed and the Baron vowed to hunt Flynn down and ultimately eliminate him for breaking his daughter's heart.

Role in the series
In "Beyond the Corona Walls", Stalyan is reunited with Eugene and Lance when they are captured and taken to her father's castle. Upon their reunion, Stalyan reveals that she still harbors feelings for Eugene and believes they are meant to be together, both as partners in crime and life. Stalyan and the Baron force Eugene to keep his original promise to marry Stalyan, but Eugene refuses. To better "persuade" Eugene, the Baron releases his Kai spider onto Lance, poisoning the latter with venom. The Baron promises to hand over the antidote, so long as Eugene compiles with their demands.

Stalyan and Eugene return to the city and wait backstage as the Baron announces their engagement and upcoming wedding to the citizens of Vardaros. Eugene pleads for Stalyan to call off the plot, as he is already in love with someone else. Surprisingly, Stalyan is already well aware of Eugene's love for Rapunzel, including the circumstances of how they met. However, Stalyan manipulates Eugene into doubting his relationship with Rapunzel, questioning why the princess would give up her freedom and marry him after spending the bulk of her life confined in a tower. Shortly after, Stalyan goes on stage to make her appearance and soon after the Baron introduces Eugene as her fiancé, shocking Rapunzel, watching from the crowd.

Rapunzel approaches the stage, demanding an explanation, of which Stalyan provides by claiming that Eugene has joined them. Rapunzel refuses to believe Stalyan's claims, but Eugene—seeing Lance growing weaker—is unable to reveal the truth to Rapunzel. Eugene soon leaves alongside Stalyan, the Baron and Anthony the Weasel, leaving behind a heartbroken Rapunzel. Back at the Baron's castle, Stalyan visits Eugene in his prison cell. Eugene once again pleads for Stalyan to call off the wedding and give him the antidote to save Lance's life. Stalyan ignores Eugene's pleas and instead reminisces about their shared past, revealing that she genuinely believes they belong together.

The wedding ceremony begins as Stalyan is walked down the aisle by her father. The Baron begins to officiate the wedding, but is interrupted when Rapunzel reveals herself during the ceremony and declares her love to Eugene. Rapunzel touches the black rocks, intending to create a shockwave by releasing their power, but is suprised when she is unable, confusing Stalyan and the Baron, witnessing Rapunzel's attempts. A fight soon ensures between the Baron's henchmen and Rapunzel, Cassandra, Hoot Foot and Maximus. Stalyan attempts to escape with a captive Eugene, but Rapunzel prevents her, engaging in a tug-of-war with Eugene at the center. Pascal creates a distraction by startling Stalyan, setting Eugene free from her grasp. Eventually, the Baron and his henchman are defeated and are forced to flee. Stalyan carries her injured father and leaves, but not before informing Eugene that she will someday settle things between them once and for all.
