Reposting about Megatron from the Batman thread
Transformers Prime (2011): Season 1 and 2 of that show were great and Megatron in that show was one of the best depictions; intelligent, clever, powerful and with an imposing, yet sleek design. More importantly however, he was expanded on as a character., becoming more than a stereotypical "I'm evil just because!" of the 80s. He was a former slaveesque miner who was thrown into gladiatorial fights in the pits of Kaon on cybertron. There his skill as a fighter led to triumph, becoming its champion. His popularity grew to the point where he rallied support from the citizens of Cyberton, using his charisma and oratory skill. He led them against the cybertronian council; corrupt and hierarchical, to demand change. However he was corrupted by the greed for power, and lacked political savviness unlike his upper-class Archivist protege Orion Pax, thus leading to a path of darkness and fascism as the latter became selected to be a Prime (becoming Optimus Prime). This lead to the civil war in which Optimus became leader of the Autobots (and where the old caste system was thrown away in the face of war), and becoming the new face of the people.
In other words, a people's hero had his path as a revolutionary turn to the darkness of fascism and his class-traitor protege became the new people's hero and revolutionary, quite similar to real life revolutions among humanity (something pointed out by the show).
This is an ironic change since G1 Orion Pax (pic 4) was originally a dock-worker autobot (since autobots and decepticons are separate peoples for some reason). He idolized Megatron and the re-risen Decepticons as new and improved due to their ability to fly as well as also being able to transform like their autobot counterparts (because originally decepticons could not transform). Only to be revived as Optimus Prime when Megatron raided the energon warehouse he worked at.
Megatron meanwhile was essentially like the Nazis, intent on reviving the decepticon people and being rulers of cybertron, essentially mirroring fascist cries of 'reviving the greatness of the past'. Orion's infatuation was part of fascism's populism before reality showed the error in that belief.
