Papi

Papi is the primary deuteragonist in Beverly Hills Chihuahua and the main protagonist in Beverly Hills Chihuahua 2. He is voiced by George Lopez in both films.

Beverly Hills Chihuahua
Papi is a male Chihuaha who belongs to Sam the landscaper. One day, Papi notices Chloe lounging by the pool, and he immediately develops a crush on her. He woos her with a grasshopper and calls her "Mi Corazone," but she rejects the gift and Papi as well. Later, when Papi finds out that Chloe was dog-napped, he sets out to find her because he is in love with her and deeply cares for her.

Chloe gets caught by Vasquez (thanks to the GPS he had placed on El Diablo's collar, which he used to track her) and is locked in a cage. Fortunately, Papi arrives and helps Chloe escape, although he gets captured as well. When Chloe frees him, Diablo corners Papi while Vasquez tries to catch Chloe. When Chloe discovers her inner bark and scares Vasquez away, she then attacks Diablo, although he merely throws her aside, knocking her unconscious.

After Diablo is defeated by Delgado, Papi discovers Chloe passed out and assumes she is dead. With tears in his eyes, Papi begins soothing her with beautiful words that explain how much he loves her. Chloe wakes up and tells him not to stop. Papi is relieved that she is okay and even happier that Chole finally accepts his love for her. Sam and Rachel find the two dogs and take them home.

Back in Beverly Hills, Papi and Chloe relax on the patio. Chloe thanks Papi for his help and tells him that she loves him in Spanish, and she licks him down to the ground as her way of showing her love. Before the end credits, Papi explains what happens to the dogs (Chloe's friends that she met in Mexico), and he and Chloe have five puppies.

Beverly Hills Chihuahua 2
Papi reappears in the second film with his wife Chloe. They have five puppies named Papi Jr, Lala, Rosa, Ali and Pep, which they try to keep up with. Papi tells his kids some incredible tales about the heroic Chihuahua. However, he embellishes his stories to the point in which the puppies end up causing mayhem. Later, Papi and Chloe, along with Delgado and Pedro, participate in a dog fashion show to win a large cash prize that would save their family's house. Though Papi had initially won, because of the lack of breed papers, he is disqualified. The dogs lose to an arrogant French poodle named Appoline.
