Buzzar

Buzzar is a buzzard-like enemy that was hired by Bowser to stop Mario. He resides in a nest at the end of Mt. Rugged during the events of Paper Mario. However, the large bird is not the smartest of Mario's enemies. As such, when Mario is stopped by Buzzar on the mountain bridge, the plumber can claim his name is Luigi (Bowser can be blamed for not giving Buzzar a clear, colored picture, and for not mentioning Luigi). Since Bowser is looking for Mario, not Luigi, he allows the hero to pass and continue on his adventure. However, if Mario claims his name is Princess Peach, Buzzar becomes enraged and thinks that Mario is making fun of him because the bird knows that the Princess has been captured by Bowser (thus, a battle commences). Of course, if Mario tells the truth, he will have to fight the bird boss.

Note: If Mario claims he is Luigi, Buzzar will continue to stop Mario every time the plumber crosses the bridge. As long as the hero keeps saying he is Luigi, Mario never has to fight this boss. He can also return stronger and quickly defeat Buzzar to gain Star Points. After being defeated, Buzzar jumps over the edge of the mountain, never to return.

Buzzar is mentioned in Paper Mario: The Thousand-Year Door. The entrepreneur Lumpy actually travels to Mt. Rugged, and has his backpack stolen by Buzzar. Mario can read about this event in Lumpy's diary.

Buzzar is a male. He is often mistakenly confused with being a female because he helped with watching over his eggs.

Trivia

 * Buzzar's name is a pun on "Buzzard", taking away the "d". It could be also a pun on "Bizarre", however, if it was so easy, Buzzar's name could also be "Buzzare" or "Bizzard", but Nintendo called him simply "Buzzar".
 * Buzzar talks with a country accent.
 * Buzzar, like Kent C. Koopa, Anti-Guy, and The Master, is an optional boss.
