Please note Hero Factory is a replacement for LEGO Bionicle
Hero Factory has the same technic like pieces as Bionicle did.
However the storyline is much, much, much different from Bionicle
Each Hero has a template like sign with an 'H' on it. This indicated they are a Hero.
The storyline is based in Makuhero City. The largest building of the city is the Assembly Tower, located in the center of Makuhero City. It employs a total of 11,127 employees. This tower is the Hero Factory that constructs various robot heroes which are sent out when the Call Center receives calls from attacked people. They can report their emergency and call on a robotic hero. Founder of the Hero Factory is Akoyama Makiro.
