Tharks are a fictional alien race from the Barsoom series, created by author Edgar Rice Burroughs. They inhabit the planet Mars and are known for their tall, green skin, four arms, and tusks. Tharks are often depicted as fierce warriors, living in a tribal society that values strength and combat skills. The Tharks have a complex culture, with a strong emphasis on honor and bravery. They are often in conflict with other Martian races, such as the Heliumites. Despite their aggressive nature, some Tharks, like Tars Tarkas, show a capacity for leadership and compassion, challenging the stereotypes of their kind.
