This was the first English-dubbed Japanese TV series in Hawaii (in 1975). Produced by Tsuburaya's Hawaii branch, it was dubbed by the Commercial Recording Company in Honolulu, and the voice talent consisted of several students from the Speech Department of the University of Hawaii.
The 1985 English-dubbed version done in Canada by Turner and Cinar features an entirely new animated opening sequence (along with a new synthesizer soundtrack). After the TPS (Turner Programming Services) logo, there are animated images with the Ultra Garrison logo (spinning around Earth, from which two Ultra Garrison mecha fly), an silhouette of Dan Moroboshi (wearing the sparkling Ultra-Eye glasses, which transform him into Ultra Seven in the show), which transforms into Ultra Seven. After that, there is a burst of light, followed by the "Ultra 7" logo, which is enveloped in black when an animated Ultra Seven flies into the screen. This is then followed by the show's weekly episode title (in yellow text against a black background), right before the episode begins. The same silhouette of Dan Moroboshi is flashed for commercial breaks, and the image of Ultra Seven (after the Dan silhouette is transformed) is featured during the closing credits.
The Hawaiian English-dubbed version follows the same exact formula as the Japanese version's credits, complete with the same crumbling sand and silhouettes (with the translated "Ultra Seven" theme song), but the show's title (complete once the "crumbling sand" effect was finished) had a black "ULTRA 7 SEVEN" superimposed. Alternately, there was also a growing colorful "pinwheel kaleidoscope" effect, with a ghostly blurred/ distorted "ULTRA SEVEN" finally taking shape once the red "7" darts into place from the camera.
The main title credits begins with a backwards "crumbling sand" effect of the Japanese "Ultra Seven" title, in white with a colorful psychadelic background. In later episodes, a "paint-swirl" title almost identical to that of Ultraman: A Special Effects Fantasy Series (1966) was used. In either case, the subsequent opening credits (which usually start with the name of the weekly episode) are accompanied with black silhouettes of the Ultra Garrison mecha against a colorful looped liquid background. The last silhouette is of Dan Moroboshi (the show's hero, decked out in Ultra Garrison uniform and helmet), which transforms into a silhouette of Ultra Seven.
