Operation Enhance

Operation Enhance was an upgrade issued by the Hero Factory to add mechanical additions to standard heroes. These weapons were made out of the technology discovered in the Minifigure and Technic universes, allowing the heroes to have technology previously not accessible. However, not only were the heroes promoted, but some Toa such as Takanuva and Zenerius recieved upgrades as well to combat the rival forces.

History
The Demitoa named Exerius was the first to devise a hardsuit, effectively beginning the operation. After Exerius suggested the Hero Factory begin a new upgrade campaign, they immediately enabled the Assembly Tower so they could implement the robotic implants. Exerius' brother, Seirez, eventually recieved the blueprints to the hardsuit, so he managed to develop his own very powerful version. Only weeks later, after the rifts between the LEGO universes began opening, the Hero Factory knew that a new device must be put to the test. They created the TAM, also known as the Technologically Advanced Mechsuit. Seeking the upgrades, Toa Takanuva and Toa Zenerius warped to the factory to get themselves a taste of the tech.

Other Information
Operation Enhance was one of the first upgrade campaigns to include both Toa and Heroes. This operation was started to combat the attacks from the Minifigure universe ever since the rifts between worlds had opened. The Minifigures had stolen technology from Makuhero City and Spherus Magna, therefore giving them large advantages in the war.
