Bufalo Rojo is a giant Native American man who appears at the very end of El Espíritu de la Tierra, looming over the Ninja Turtles from behind. In the following chapter, El Espíritu de la Tierra: La Continuacion, he and the Turtles fight, and he absolutely trounces them. It is only through Kutuk's intervention that the Turtles are spared. Kutuk explains later that the two of them are sentinels of Mount Shasta, guarding it against those who would arrive with malicious intent.
Bufalo Rojo is a large Native American with a stereotypical appearance of long hair, a headband, and war paint. He is shirtless and wears jeans and moccasins.
Bufalo Rojo is fond of fighting and very good at it - enough to beat all four Turtles at once. He apparently speaks no Spanish, which vexes the Turtles, and only communicates through pseudo-aboriginal gibberish, which is subtitled in Spanish when he speaks to Kutuk. When Kutuk stops the fight, Bufalo Rojo walks away, noting that he'd had his fun.
