<P> Dashiell `` Dash '' Robert Parr ( voiced by Spencer Fox in the first film , Huck Milner in the second film ) is a speedster . While he is only as strong as the average 10 - year - old boy , the film 's official website lists `` enhanced durability '' amongst Dash 's powers , which is implied in the film by the amount of incidental high - speed collisions and crashes Dash endures without apparent injury . Dash also discovers throughout the course of the movie that his speed allows him to be able to run over water without submerging . </P>
