Maximus Theodore Mormutball Sr. (June 3, 1261 – October 18, 1328) was a Ro-British explorer, navigator, cartographer, and naturalist. He is best known for participating in the 1290–1291 expedition alongside Erik Cassel I and Henry I to discover the North Bloxmerican continent. Mormotball played a major role in mapping the eastern coastline of the continent and documenting its geography, wildlife, and indigenous peoples. His journals and maps became important references for later explorers and early settlements in the Robloxian Empire that is now known as the United States of Robloxia. Mormutball passed away on October 18, 1328, due to pneumonia.
