Magua and Uncas
Uncas is the example of a "good Indian" that we are given as a counterpoint to Magua's "bad Indian." We never see Uncas drink or manipulate people (unlike Magua), and while Magua loves to give extemporaneous speeches like every good villain, Uncas is reticent in the extreme…which makes his brief forays into the world of speech all the more touching.
Note also that they are involved to some extent with the same woman—Cora. She rejects Magua repeatedly while crushing hard on Uncas.
