The same was done with the "Dragon King", which was not one of the game's bosses; the dragon's head and neck were composed of sprites, while the rest of the body was considered part of the background. The dragon's neck stretched out vertically due to NES hardware sprite limitations horizontally. The animation of the eagle (the "Eagle King") that transports Kuros to the Wind Elemental was one of Ste Pickford's first graphics which he drew for the NES. It was done in Deluxe Paint for the Amiga with sketching done by mouse - without assistance from graphics tablets or other scanners. He took eagle drawings from a book on animals in motion by Eadweard Muybridge. Pickford wanted to show off the possible graphical capabilities of the NES; he said, "I wanted to do something 'flashy' early in the game, trying to show off my amazing graphic art skills on the rather primitive NES. We were working on Amiga and ST games at the same time, so were always trying to push the NES with bigger and better graphics, right from the start of our work on the machine." The eagle consisted of only three colors and between 11 and 17 sprites per frame of animation. There was a smaller version of the same eagle, which was used as a regular enemy in that level. Development of the game's title screen was inspired by loading screens that were used in most computer games at the time; the objective was to create a nice-looking graphic while waiting for the game to load, even though the NES, more rooted in arcade traditions, did not require that. Pickford spent most of his character space on the title screen image; he was limited in the number of available colors due to the more limited graphic capabilities of the NES (as opposed to most home computers), as it was more designed for scrolling and animation and not for stationary graphics. The sword in the title screen used character sprites and used a different palette from the picture of Kuros himself; the sword had to be vertical as the NES hardware did not allow for too many sprites horizontally. Pickford planned to use, and completed, an Ironsword logo of his own when Acclaim made him use their planned logo, which he said "was a bit more bland and blocky, with detail that didn't work very well at
