It is well known that superluminal propagation of small fluctuations around nontrivial backgrounds is possible even in Lorentz invariant and generally covariant theories. This possibility changes the causality and universality of the Horizons and Hawking temperature. In this talk I will first discuss, the Cauchy problem and why causal paradoxes are absent in these theories. Then I will consider the Black Holes thermodynamics in the presence of the superluminal propagation.
