Spectrobe Masters are individuals capable of commanding the Spectrobes, they are chosen by the Spectrobes to lead them.
Spectrobe Masters are the only ones that can awaken the Spectrobes with their voice and command them in battle. They will not respond to another person's commands, with the exception of the master's partner.
Bond with Spectrobes[]
"There is a special bond between fossils and Spectrobe Masters. The creatures live with their master, fight alongside them, and when the master passes away, their Spectrobes fall back into a fossilized state until the next master comes along. They are passed down from master to master, like some ancient teaching.
When a Spectrobe falls back into slumber, they sometimes take with them special memories and messages from their former master. When another Spectrobe Master comes in contact with the fossil, the Spectrobe can sometimes show them the memory through a flashback or sorts."

The Krawl War[]
In ancient times, the Krawl began a giant invasion which was focused mainly on the Kaio system. Here, every Spectrobe Master found in the system stood up to fight against the attacks, and many of them sacrificed their lives for their home. 100 Masters aided by 10,000 Spectrobes took up the battle and fought back, thus saving their system. On Menahat a Legendary giant Krawl known as Zabacraw fell upon the planet and formed a crater known as the Pit of Ruin during this time.
On the planet Slayso, a giant tower was erected to serve as a memorial to the Krawl War.
