These were chase figures available 1-per-case in regular figures (except for the #0 Prime which was a hobby shop release). Each figure was reportedly limited to 5,000 pieces each, but the #0 Prime was reportedly around 3,500.
The last several figures released as part of the Ultra 5000 chase series were rumored to be limited to 504 pieces (some say fewer) because the line was scrapped before all 5,000 could be produced and shipped. These are listed in the Ultra 504 series.
Capable of Earth-to-Moon flight, survival of multi-megaton explosions and acts of major destruction, PRIME is considered the most powerful Ultra in the world—and an unstable and dangerous renegade. Beneath his amazing exo-body he is a 13-year-old boy, the very human Kevin Green.* (*See PRIME Comic Book #1. –Ultra Editor)
