Razor

Prime: (spoilers)

Razor landed on Earth and seemed to be an average Decepticon, hating humans and pledging loyalty to Megatron. Going as far as making a Neckromanced Decepticon guard for himself and the team while also becoming a surgeon for the whole ship. However, when he landed he met a human named Jasp. Despite his loyalty to the Decepticons, Jasp seemed to change him and his view on human life and Earth. As the war raged on between the two factions, Razor changed and saw that both factions had it's ups and downs and inevitably chose to leave both factions and become independent. When returning to Cybertron, he sided with the Autobots to rebirth the planet. In the end, he decided to stay on Earth for it's vast beauty and to become Jasper Nevada's caretaker. Learning to fight and sharpening his skills in the medical feild.  

RID2015:

During this era, Razor continued to live in Jasper Nevada. After the death of Jasp, his human friend who he considered family, he began becoming more silent. More independent. He inevitably took on the role for re-homing Cybertronians and making a small colony on Earth of bots who did not want to be in a faction. They were called Communicons. Since becoming leader, he took on a new project in finding a cure for his hereditary blood disease.
