Most of the titans in Attack on Titan are Pure Titans, which are completely mindless titans that are deformed to some point. But then you have the abnormals, which seem to be a degree smarter. Connie Springer's mother was an abnormal, as seeing that she could talk (or at least tried to).

Rod Reiss' titan was also an abnormal (but I suspect this being due to his royal blood). Do you have any theories for what abnormals are?
