The Texan in Joseph Heller's "Catch-22" initially appears to be a likable character, characterized by his good nature and generosity. His charm makes him seemingly appealing at first, and he quickly captures the attention of those around him. However, as time passes, the initial impression fades, revealing that his personality becomes increasingly intolerable to others.

This shift highlights a common theme in the book: the complexity of human interactions and the façade people can maintain. The truth about the Texan emerges, demonstrating that what seems endearing at first can quickly become overwhelming, leading to a sense of discontent among his peers.
