I don't know, most of the villains in these 3D-CGI movies fail completely at being scary. Other than Hopper, Tai Lung, and arguably Syndrome, then we have... Gargamel? The completely bland fossas and the Smug Snake
lion in the Madagascar movies (Dubois was a fine villain, but not exactly scary)? The super-gorilla from Megamind? Lord Faarquad and Prince Charming? The midget pheasant from Kung Fu Panda 2? A random bear in Over the Hedge
? Prospector Pete (I don't think too highly of Sid or Lotso in terms of public intimidation either)?
Animation movies nowadays don't have, for the most part, the freaky scare factor villains like Maleficent, Judge Doom or the T-Rex from the first Littlefoot movie had.
Praise the Lord.
