A sage who overthinks, overplots, and overanalyzes every possible outcome. They're like a human version of HAL 9000, but with more navel-gazing.
Their thoughts revolve around the meaning of life, the purpose of the universe, and the best way to optimize the coffee-to-milk ratio in their morning latte.
Warning: approaching an Overthinker can be hazardous to your mental health. Prolonged exposure may lead to existential dread, self-doubt, and an increased risk of getting stuck in an endless loop of what-ifs.
But hey, at least they're good for a laugh.
