Other metal
The Semi-Hero packs in "GB2" were a new addition to the packs used in filming. These packs were stripped-down versions of the heroes, merging constructional concepts from both the heroes and the stunt packs into a mid grade pack for wide shots. These packs were also constructed lighter for the actors. many of the metal parts from the Hero packs were cast in resin and attached to the shell, such as the HGA, injector tubes, beamline and filler tube. Other metal parts, such as the Ion Arm, Booster Tube (and frame), PPD, and N-Filter, were actually cast into the shell, much like the foam stunt packs from the first film. These packs also had fiberglass cast wands, instead of the metal ones from the first film.
