Basil SquarePantis (1425-1525) was a human Byzantine government official who, as a human-fish hybrid, founded the House of SquarePants in Bikini Bottomshire, after escaping Constantinople when the Ottomans attacked it in 1453 and led a long march which lasted until reaching Bikini Bottomshire in 1456. Basil was known for his adherence to the idea of chivalry. He spared all his enemies and their subjects, and they became loyal to Basil, further strengthening his power in the Kingdom of Bikini Bottomshire, which he ruled.
