El Chupacabra (Scooby-Doo)

El Chupacabra is the main villain of Scooby-Doo and the Monster of Mexico.

Scooby-Doo and the Monster of Mexico
We first catch sight of El Chupacabra when Fred's pen pal Alejo is playing xylophones in a celebration with his young son Jorge, along with their chihuahua Chiquita. They continue to play until Chiquita hears a terrible roar and notices an eerie green light. She runs off and Jorge follows. The boy and his dog run into the monster himself and as El Chupacabra swipes at Jorge, Alejo comes to his rescue and, running into town, cries out "El Chupacabra!" The townspeople, hearing this, run away in fear.

When Scooby-Doo and the Mystery, Inc. gang arrive and meet up with Alejo, he warns them about the menacing beast.

Shaggy and Scooby-Doo fall asleep and hear a noise, believing El Chupacabra is breaking into their home, but it turns out to be Fred.

When the gang search for El Chupacabra and seek advice from a medicine man, little do they know that he is watching them. Alejo and his friend Luiz do the same thing until he is ambushed by El Chupacabra, who charges after him. He plunges over the edge of a cliff but saves himself in the nick of time and climbs up to safety.

Fred, Daphne, and Velma realize that Shaggy and Scooby-Doo are missing. As they search for the two friends, they run into Luiz and Alejo and the monster attacks. After a huge chase, the three of them manage to escape.

The group realizes that the actor Mr. Smiley is trying to force the Mexicans to sell the land. El Chupacabra appears once again and terrorizes the village. The monster charges after the friends, who trick him into getting his head stuck in a beehive. El Chupacabra is finally captured when he gets tangled up in a string of lights. The monster is revealed to be a crafty museum guide, who turns out to be Luiz's girlfriend, Charlene, who has used him for his money. As the crooks are carted off to jail, the friends celebrate their victory.

Trivia
