What role do 'chibi' characters play in manga, and how are they drawn?

Chibi characters are super-deformed (SD) versions of characters, drawn with oversized heads, small bodies, and simplified features. They're used for comedic relief, flashbacks, or to represent a character's inner thoughts or feelings. Chibi characters are typically drawn with large, round eyes and minimal detail, emphasizing cuteness and humor. They offer a stylistic break from the more detailed regular character designs.
