Based around the LEGO toy line of the same name, Hero Factory is set in a place known as Makuhero City. Here, Heroes are built in the Hero Factory and sent on missions around the universe, dealing with a variety of galactic problems such as alien infestations, natural disasters, and criminals.
Three Heroes are caught up in a futile fight against the acid-spewing Corroder, and their only hope is to form a shield, using their energy reserves. But their Hero Cores are nearing depletion, so William Furno decides to jump into action and save his friends.
