has machine guns on his backside like in the 1980s series, however this time they fire actual bullets, instead of lasers. His finger lasers “digibeam” is absent. Instead of the arm cannon in the 2003 series, it is changed to full arm blasters in both arms. Also, his arm rockets are absent, although his arm cannons can also serve as a means of propulsion. In the 1980s series, Astro’s eyes act as lights, while in the 2003 series they allow him to analyze things. However, in the film, they are also lights, although they can see through skin or tissue imitating skin, much like an X-ray. Also, Astro retains his super hearing and strength, as well as rockets in his feet. Another difference is Astro’s source of power. In the original series, he is powered by atoms (hence his Japanese name), but yet in the film he is powered by the Blue Core Energy, made out of pure positive energy. It is unknown as to why the writers changed his power source. Also, this is the first time that Uran does not appear at all.
