Catalina Bernabeu

Catalina Bernabeu is the main antagonist of the Colombian teen series Isa TK+, which is a sequel to Isa TKM. She is played by Carolina Gaitán.

Traits
Catalina pretends to be a sympathetic, tender and affectionate girl, but in reality she is arrogant, deceitful and aggressive.

Story
After her success as a singer, the protagonist Isabella "Isa" Pasquali and her friends start at a new school in Colombia. Catalina, who is secretly in love with Isa's boyfriend Alejandro "Alex" Ruiz, approaches Isa faking a sincere attempt to become friends, while in reality she wants to harm Isa's career to drive her away from Alex. At chapter 2, it is mentioned that Catalina's mother is a woman who travels the world and doesn't spend much time with her daughter, what possibly explains Catalina's evil personality.

Catalina allies with Cristina Ricalde for a certain time, but in chapter 39 this allegiance is broken because Cristina didn't respect her. Catalina avenges herself in the next chapter by making her go expelled.

Catalina reveals her true identity to Isa at chapter 59, saying that she is happy that Isa had lost her contract, her friends and Alex. At chapter 62, by means of blackmailing, she manages to eliminate Isa's fan club and create one for her instead.

Near the end of the series, Cristina allies with Isa as part of a plan to revenge Catalina. The plan succeeds and, in the last chapter, Catalina is sent to another school where she undergoes severe disciplinar punishment.

Appearance
She has brown hair and eyes and is 17 years old.
