Don Eleuterio was depicted in the early incarnations of the character as a grumpy old man, easily angered by life's minor irritations. Recent incarnations depict him as less irritated (and more tolerant) than before. However, Eleuterio is still prone to fits of anger, and throws things quite loudly whenever he loses an argument and proof is shown to him, or when something personal happens to him that goes against his political philosophy (such as his son Elpidio joining a PDP campaign rally for a joyride, for example).
