Shockwave

Shockwave is the greatest Decepticon ever. He is very smart and logical and used this to obliterate his foes. He worked for Darth Megatron and was his favroite warrior. Starscream was extremely jealous of Shockwave, who often made clones of him. They were called Thundercracker and Skywarp. Shockwave later took over the decepticons after he defeated and exiled Darth Megatron and became a Super-Mega-Ultra-Sith Overlord. He launched many attacks on the Galaxy and teamed up with a universe traveling Supreme Leader Snoke. They then recruited a reborn Thrawn, who's intelligence combined with Shockwaves was unmatched. The trio formed the Shadow Minds and began their plans to rule the Galaxy.

Arrival
Shockwave left Cybertron with the Decepticons. their leader Megatron, then became a Sith Lord. Shockwave began planning to overthrow Darth Megatron when the time was right. The Decpeticons were followed to the Galaxy by the plot-armoured Autobots who shot down the Deceptcion ship, causing it to crash on Ryloth. The decepticons took over the planet.

Age Of The Empire
around the time of the Decepticons arrival, Palpatine formed the Galactic Empire and the senate clapped like idiots thinking it was the bet idea ever. The decepticons had Soundwave become a senator but he failed because he kept dropping diss tracks on Orn Free Taa. The decepticons decided to wait for the Empire to fall. As predicted, the Rebels blew up two Death Stars and killed Palpatine and Darth Vader. The Decepticons once agin began preparations, launching many attacks and kidnapping Ewoks to kill.

Duels with the Sesame Street
The Decepticons were not safe yet. Darth Elmo rose with the evil Sesame Street. Shockwave used his intelligence to outsmart the assassins sent to kill the decepticons. Only Soundwave was killed. Darth Elmo attacked Ryloth and the Decepticons fled the planet. They began a war with Sesame Street. At the same time, the Rebels started a war with Sesame Street. Dam, Sesame Street is screwed. Shockwave killed two members in a week using precice idiot detecting missiles.

Shockwave later led an attack on a Street outpost where Big Bird was. Shockwave and Big Bird had a long fight, ending in Big Bird retreating. All others in the outpost were killed.

The war re a turning point when Darth Elmon committed the ultimate trechary and betrayed and murdered himself due to his insanity. Not long after, Sesame Street fell apart and all its members died or were killed. ( minimal difference really ).
