Long time ago.. when our planet, Cybertron still alive, lived a three guardians. They were Omegaron, Alpharon, and Deltron. Omegaron was the guardian of ground, Alpharon was the guardian of sea, and Deltron was the guardian of sky. They were guarding every part of Cybertron. Until the day that Cybertronians' beliefs are splitted into 2, Autobots, who believed that we can't take stars of planets that had a living creatures, and Decepticons, who didn't care anything about the other creatures as long as Cybertron can still live. Wars occured in almost every places in Cybertron. The three guardian were also splitted into 2 sides, Omegaron and Alpharon joined Autobot, while Deltron joined Decepticon and became Megatron's most loyal servant, more than Starscream. Omegaron and Alpharon were trying to make Deltron knows that joining Decepticon is not the right thing to do, but they ended up getting killed by one of their best friend in the past, Deltron.

One day, Megatron gave Deltron a mission to explore and collect datas about million of planets with a star in the Universe to find a giant star that can be converted into an energy to revive Cybertron. Deltron then went to so much planets. Until he came to a point in the Space and then he's gone from Megatron's Radar.
