  We study the butterfly effect by considering shock wave solutions near the
horizon of the AdS black brane in some of 3-dimensional Gravity models
including; 3D Einstein Gravity, Minimal Massive 3D Gravity, New Massive
Gravity, Generalized Massive Gravity, Born-Infeld 3D Gravity and New
Bi-Gravity. We calculate the butterfly velocities of these models and also we
consider the critical points and different limits in some of these models. By
studying the butterfly effect in the Generalized Massive Gravity, we observe a
correspondence between the butterfly velocities and right-left moving degrees
of freedom or the central charges of the dual 2D Conformal Field Theories.
