Spongebob
No entity in recorded media history displays such unwavering positive affect. Despite inhabiting a pineapple and working minimum wage at a fast-food establishment, Spongebob maintains enthusiasm levels that defy psychological explanation. His optimism persists through failure, rejection, and existential absurdity with remarkable consistency.
Wonder Woman
Diana maintains a principled hopefulness grounded in her belief in humanity's potential for good. However, her optimism is tempered by wisdom and experience, occasionally yielding to righteous anger or strategic cynicism. Her worldview represents mature idealism rather than unconditional positivity.
