Node

Nodes are devices created mainly from the gold-like substance found in the Laguna province of the Philippines that are surgically implanted on the nape of the neck, granting the person with superhuman abilities and to materialize weapons by allowing the person to manipulate light throughout the electromagnetic spectrum. They are usually shaped like short pyramids and are only a few millimeters in size. In addition, the devices are based off the only surviving sacred treasure of Japan, the jewel that Maria supposedly created.

Generation 1
The first nodes were surgically implanted into military veterans and were still in their trial phases when they were utilized against the Colossus in Manila. They were proved successful when the Colossus was defeated and prevented the being from self-destructing. The nodes were at least a centimeter in size and a subject was implanted with an average of ten nodes. They granted the subjects with enhanced strength and speed, abilities used to destroy the armor of the Colossus and its core. However, adverse effects from the nodes were eventually discovered with the subjects' bodies physically deteriorating due to the nodes' immense power not being able to completely controlled by the subjects. This would cause subjects to experience symptoms similar to that of radiation poisoning which caused this line of nodes to be discontinued and scientists to create a more compatible version of nodes.

Generation 2
Two years afterward, a new streamline version of nodes were created that were smaller compared to their last generation counterpart, but were more compatible with the human body. Because of this, they were less likely to cause adverse effects like radiation poisoning that were seen from the last generation of nodes. In addition to being streamlined, users can also materialize light into blade and blunt weapons that were used to better fight against the Colossus. The technique used to create these weapons is similar to the way holograms are made, but are completely physical.

Generation 3
Another generation of nodes were created three years later that were a more compact version compared to the last generation and allowed a new class of disc-shaped weapons to be used that could fire concentrated beams. These weapons could only be used through psychokinesis which was the new ability introduced with this new generation of nodes. The new features enabled users to better fight the Colossus at a distance while still being reliable in battle.
