The Pig King Statue

The Pig King Statue is a boss in the game Super Smash Bros. Brawl. Although Sakurai lists it as a boss, it is not actually counted as a boss. In the Subspace Emissary, Lucas is visiting The Ruined Zoo, but after he sees the Pig King Statue, he runs away. Lucas must travel through the zoo avoiding the Pig King Statue. However, soon, he trips over, and just when he thinks it's over, Ness comes and uses his PK Thunder and PK Flash to destroy the large statue. But once destroyed, it turns into Porky, an actual boss that is fought.

Aside from the Subspace Emissary, the Pig King Statue also receives a trophy and gets to be in the background of the New Pork City stage.

Trivia

 * To unlock a trophy of it, one must complete Boss Battles on Very Hard difficulty.
 * In Mother 3, the original game that the Pig King hails from, one of the random effects of PK Flash is immediately destroying the enemy. This may be why it works so well for Ness in the cutscene. However, players can't do this manually if they replay the stage as Ness - they must survive until the cutscene sequence.
 * Likewise, players can't use Trophy Stands against the Porky Statue, as it's invincible.
 * In Mother 3, before being battled in New Pork City in Brawl, it stands similarly to the Statue of Liberty in real-life.
