So for those of you who may or may not know, I am writing my own take on the Hero Factory 'movie' or first four episodes and just thought I'd like to share my theories on HF and how it can be more serious.
It stands to reason that not every world would be comfortable with the idea of these heroes protecting their planet. After all, with an omnipotent force such as HF around can easily replace a planet's military or police force as everyone will just rely on the heroes to fix their problems. Hero Factory deals with difficult moral values, as the motto is that 'heroes are built' (rather than 'heroes are made') which means only heroes that are built in HF can be heroes.
It stands to reason that since Makuro insists on these bots being called heroes, that everyone else naturally is not a hero. How Makuro has funded this idealistic project has yet to be revealed, though the key could lie in how many Assembly Towers exist in the galaxy.
If Makuro sets up other towers on almost every world with an HF contract (or at least for every alien race) makes Hero Factory more of a corporation than what LEGO has made it out to be. Every robot in this galaxy seems to have a 'core' to power themselves, but only heroes get a special kind of core. The quaza stone and the rarity of it could possibly only exist in Makuhero city, with Mr. Makuro being the only one with access to it. This notion raises another question that if everyone knows what a hero core is made from then why is no one but Makuro allowed access to it's vaults? What is the secret of Hero Factory if there is one at all?
Also if a world has a contract with Hero Factory for protection service, then are the heroes even allowed to touch upon the worlds that are not signed up with them, even if millions of people are in mortal danger? I cannot help but think that Makuro is such a fantastic villain, I mean read anything that LEGO produced he has 'written' and just thing of the Dath Sidious in star wars. It just fits so well. To add, think about the name MakuHero City along with 'Makuro.' The titles sound very similar and it's not so farfetched to think that the city named itself after him and his company. This possibility just gives an aura of arrogance to this mysterious character, does it?
