Bosco

Bosco is the main antagoniste of the 2010 family comedy movie Marmaduke. He is a Aggressive Beauceron the tyrannical Alpha of the Orange County Dog Park in California as well as the leader of a dog group consisting solely of pedigrees until the day Marmaduke, a Dane from Kansas arrived and upset his tyrannical reign.

Personality
Because of being a pedigree which he is absurdly proud, Bosco believes himself superior to the dog considered mutts, showing them only contempt and virtually no respect. Like the Alpha, he declares openly that he is the one who makes the law in the park.

He also has a strong taste for bullying, as when he scares Marmaduke when he meets him.

Bosco is also very arrogant, cruel, perfidious, manipulator and particularly contemptuous.

He is also very angry and jealous, as when he learned that Marmaduke was interested by Jezebel, he warned him that if he continued, he was dead and when he lost the surf contest, Bosco becomes so upset that he chases savagely Marmaduke.

Despite everything, Bosco turns out to be a coward when Marmaduke finally stands up to him and makes him so afraid that he simulates a cramp on his leg. After being ousted from his Alpha rank, Bosco's fear was replaced by an even greater disdain than before against the Kansas's dog. He fully recovers his former trust when he exposes Marmaduke for lying on the cat that he had supposedly driven out of the park. During his last meeting with Marmaduke in the film, Bosco was no longer afraid of the Dane and asked him if he wanted to fight.

He shares with Marmaduke the fear of the bees, spanking him from fear in a comical manner when he landed on his snout.

Trivia

 * Bosco may be of Hawaiian origin or at least Oceanian since the hook necklace he wears is widespread among surfers there.
