What was the meanest Indian tribe in America?

What was meanest Indian tribe in America is subjective and based on perspective of settlers and Army, but often considered meanest or most feared by settlers were Comanche in Southern Plains and Apache in Southwest, known for fierce warfare, raids, and resistance, though mean is biased term. Meanest is loaded term reflecting settler viewpoint, with tribes defending lands seen as mean by colonizers, but from Indigenous perspective they were defending homelands. Comanche were considered fiercest and most feared by settlers in Texas and Oklahoma for expert horse warfare, raids, and dominance of Southern Plains from 1700s to 1870s, called Lords of Plains, with brutal warfare tactics. Apache, especially Chiricahua Apache under Geronimo, were feared in Arizona and New Mexico for guerrilla warfare and evasion of US Army for years. Sioux, Cheyenne, and Mohawk also feared for battles like Little Bighorn. However, labeling meanest is problematic as all tribes were defending territories against colonization, with warfare practices similar to European warfare of era. So meanest tribe label often applied to Comanche and Apache by settlers due to fierce resistance and raiding culture, but more accurately they were most effective at resisting colonization, with Comanche dominating Plains and Apache mastering guerrilla warfare.
