Because of the need for energy, Brahms and his wife made an "energy treasure/leadership module/matrix" and used it to start a "solar absorber" to absorb the energy of stars. After they discovered that there was life on the earth (primitive man), Brahms vowed not to get energy from the stars for allspark in order to protect the life on the planets around the stars, because when a star died, the life on those planets would also die.
The ultimate villain in Transformers (said to be transformed into Cybertron plane) has the ability to jump in space. He is cunning, evil and cruel. The energy block is the only target he catches. Under his bewitch, Megatron formed the Decepticon Corps, and then Sebert Enxing launched a civil war.
He was one of the original 13 transformers. Dissatisfied with his kin's decision to give up energy from the sun so as not to harm the earth, he betrayed his kin and rebelled, plotting to destroy Brahms, but he was also sealed in a sarcophagus. He continued to cheat and manipulate Megatron, and was released in the movie "Change 2" in an attempt to make energy blocks with the energy of the sun. In the end, the lie was exposed and the help of Megatron and Decepticons was lost. Finally, it was destroyed by the combination of Optimus Prime and Skyfire components.
As far as we know, the fallen is one of the 13 transformers.
