Who was the most feared American Indian?

The most feared American Indian is subjective and depends on period, but often cited as Geronimo of Apache, Sitting Bull and Crazy Horse of Sioux, and Tecumseh of Shawnee, who were feared by US Army for fierce resistance, guerrilla tactics, and leadership in wars. Most feared American Indian leaders include Geronimo, Apache leader who evaded US Army for years with guerrilla warfare in Southwest, feared for raids, Sitting Bull and Crazy Horse who led Sioux victory at Little Bighorn in 1876 defeating Custer, feared for military skill, and Comanche warriors who were feared on Southern Plains for horse-mounted warfare and raids. Fear depended on perspective, with settlers fearing tribes like Comanche and Apache for raids, while Army feared Sioux and Cheyenne for organized resistance. So most feared American Indian is often considered Geronimo for Apache resistance, or Sitting Bull for Sioux leadership, with Comanche tribe as whole considered most feared tribe by settlers due to fierce warfare and horse culture dominating Texas and Oklahoma. All were respected warriors defending lands.
