Hero Factory

[Autocon]

What is the story line behind these?

[Lint]

Well they canned bionicle a year or two ago so this looks to be the replacement line. They've been flogged off the cheap not long after release so I reckon bionicle will make a comeback and everyone who grew up on them will buy because of the nostalgia attack.

If you were after the actual fiction when you said 'story', here you go. Lifted straight from wikipedia!

Plot

Far away in an entirely different galaxy than our own, there lies the surreal and high-tech Makuhero City, home to the Hero Factory, where new robotic heroes are built every day. The factory was created by the wise architect of Makuhero City, Mr. Makuro, with the intention of upholding peace and prosperity throughout the universe, fighting the worst villains and monsters from all over the galaxy. The main story revolves around the Hero Factory Alpha Team and their allied rookie heroes combating evil on several different planets.

I think Lint is spot on, their story seems to be 'We took over from Bionicle! We are heroes and do heroic things of a heroic nature for no return!'.
