The only thing limiting the destructiveness of Zweitar's rampages is the fact that its two heads seem to be incapable of agreeing on which direction to go in. Zweitar will lurch from side to side, often making little progress forward.

A Zweitar is so overwhelmingly powerful, it can bring down a whole mountain to make its nest. Since their two heads do not get along and compete with each other for food, they always eat too much.
