This thesis motivates and presents three novel results in the spectral theory of one-dimensional Dirac operators, each of which concerns various forms of exotic or distinguished spectral characteristics. First, we consider the possibility of embedded eigenvalues in the absolutely continuous spectrum of a Dirac operator with operator data of Wigner-von Neumann type. Second, we demonstrate the genericity of Cantor spectrum when the operator data is chosen to be limit-periodic. Third, we provide for the Dirac operator setting an analogue of Stahl-Totik regularity, which, among other things, provides a lower bound on the thickness of the spectrum in terms of the operator data when the data is taken to be uniformly locally square integrable.
