Later, after a lengthy time working on the process, Makuro debuts the Upgrade, a larger, stronger design that he later rolls out to all Heroes.

The colour scheme of the heroes and villains (red, blue, white, black, green, brown) was not continued in the Hero Factory theme, instead, colours like silver, gold, orange, and yellow were reintroduced. Inside, the heroes find that Surge has been taken over by a brain and has made an army of drones to destroy the factory. The remaining Heroes build more battle machines to explore the tunnel, while reinforcements from Hero Factory take on the Jumpers in the city above.

Instead, the Heroes and Villains all came in resealable plastic bag containers (except for Black Phantom, the only large set, which was still packaged in a box). William Furno, the newest hero, was eager to defeat Von Nebula but was depressed when his firm-handed team leader Preston Stormer told him he hadn't the experience to take on the most dangerous villain in the galaxy.They find an ancient transportation unit that could be used to instantly transport them to the central mine that leads to the core of the planet. From 2011 onward the characters were modeled with four-fingered fists instead of the 2009/2010 three-fingered fists. Recognizing the growing amount of evil in the universe, he created the Hero Factory, a corporation dedicated to creating Heroes to protect the galaxy. A fifth episode titled "Ordeal of Fire" debuted in April 2011, followed by two further episodes - the two part story Savage Planet - in September as a one-hour special. In the fourth wave, Breakout, every set came with a new type of Hero Core (even the villains) which came printed with a code on the back for use with the new online game.

Rocka's group arrive first at the central mine via the transportation unit, where Witch Doctor had been mining the Quaza.

The theme was centered around a group of robotic heroes who protected the galaxy from various threats. Voltix then uses the black hole staff to cause a villain breakout, leading the Heroes to conclude that Von Nebula wanted the staff to be placed inside Hero Factory for a grander scheme. The pieces in this series are not the regular Lego bricks; they include a lot of ball and joint connections which allow for plenty of movement and posability once the figures are built.

Although he has dealt with this fear directly over the course of his Hero career, Surge still deals with the insecurity, and often throws himself into action to compensate.Nathan Evo is an introspective rookie Hero working with the team, who emphasizes the use of heavy artillery in missions. As they walk into the street to help out, Breez asks Surge if this experience changed anything about how he feels to help. A facet of the Hero Factory storyline is the Hero Recon Team, based around a web application that allows users to design products using LEGO's Design byME service. He later learns that his body has been corrupted by nanobots from the sludge and, after a fight with Stringer, Bulk and Furno, escapes the Hero Factory. After two of their own were kidnapped, the remaining Heroes traveled deep underground to rescue them.
