孙悟空 (Sun Wukong) is the legendary Monkey King from the 16th-century Chinese novel 西游记 (Journey to the West). He possesses supernatural powers (72 transformations, cloud somersault, summoning a magical staff from his ear) and a rebellious, witty personality. In modern Chinese culture he symbolizes intelligence, courage, and defiance of authority, and you'll see him referenced in idioms, social media memes, and casual speech (e.g., 孙悟空的火眼金睛 'Sun Wukong's fiery golden eyes' for sharp perception).
