We prove that for each characteristic direction $[v]$ of a tangent to the identity diffeomorphism of order
$k+1$ in
$(\mathbb{C}^{2},0)$ there exist either an analytic curve of fixed points tangent to
$[v]$ or
$k$ parabolic manifolds where all the orbits are tangent to
$[v]$, and that at least one of these parabolic manifolds is or contains a parabolic curve.
