The character of Ultraman went through many changes as pre-production went along. At first, the planned series "Woo" had a corporeal space creature with eyes, who befriended a reporter named Jôji Akita, but the Self Defense Forces were after him. This was basically the monster version of "Doctor Who"
(1963), and Woo's personality was comical. Then they planned "Bemular" (retitled "Science Patrol - Bemular") about a defense force disguised as an art/photography team. One of the members, little did anyone know, gained the ability to transform into a giant birdlike humanoid monster called Bemular (this is not the same Bemular that Ultraman would fight in Episode 1), who defends Earth from monsters, aliens and other threats. Unlike Woo, Bemular was a tough and righteous fighter (Bemular looked very similar in design to the title monster of Daikyojû Gappa
(1967)). This then evolved into "Redman," the title hero of which slightly resembled Ultraman as we know him, but he looked more demonic and had horns. Both Bemular and Redman were designed by Tôru Narita
, who came up with the final design for Ultraman based on his Redman design, now resembling a less-scary Buck Rogers-style alien being (with a bit of the iconic "Roswell Alien" as well). The characteristic "ColorTimer" (the "warning light" on his chest) was added at the eleventh hour.See more
