Megatron (Michael Bay pentalogy)

Megatron is the main antagonist of the Michael Bay Pentalogy of Transformers, since Transformers 2: Revenge of the Fallen, he was simply just an antagonist as The Fallen for Transformers 2: Revenge of the Fallen, Sentinel Prime for Transformers 3: Dark of the Moon, Lockdown for Transformers 4: Age of Extinction, and Quintessa for Transformers 5: The Last Knight took the role of main antagonist in their respective films.

Weak, Puny, Bad Qualities

 * 1) Megatron's personality consists of being nothing other than an evil, brutal, psychotic, homicidal killing machine.
 * 2) In Transformers 2: Revenge of the Fallen, he and Scalpel tortured Sam Witwicky by attempting to remove his brain for "science".
 * 3) When he became "Galvatron" in Transformers 4: Age of Extinction, he used Transformium just to "transform" from one mode to another.
 * 4) Speaking of his new name "Galvatron", he doesn't stay faithful to that name. In Transformers 5: The Last Knight, he became "Megatron" again.
 * 5) We never even get to find out how he became Megatron again
 * 6) Back to Transformers 2: Revenge of the Fallen, he barely uses his tank mode (which was made for the sole purpose of merchandise).
 * 7) His design looks quite ugly for a Decepticon.
 * 8) He died multiple times and was brought back after nearly every death. This can appear excessive and a poor attempt at keeping Megatron a reoccurring villain.
 * 9) Starting from Transformers 2: Revenge of the Fallen, he wasn't given much of a good spotlight and he was treated as mostly a punching bag in the fight scenes.
 * 10) * However, in Age of Extinction, he does put up a good against Optimus Prime in a short fight scene.
 * 11) In Revenge of The Fallen, he is pathetically man-handled by Optimus Prime, getting talked, getting parts punched out, and getting his leg mutilated. He literally needed Starscream and Grindor to help him out. The only reason why he won was because he ambushed him.
 * 12) He was a complete idiot for making some idiotic moves such as trusting Sentinel Prime to be his partner only to be betrayed by the latter and losthis army of KSI Drones, including Stinger, to the combined alliance of Autobots and Dinobots just over a Seed when he only had 50 of them which he could have at least have many more to his army then cowers off in anger when it doesn't go his way.
 * 13) He abuses his second-in-command Starscream in anger which is very repetitive and mean-spirited.

Good Qualities

 * 1) He was not as bad in Transformers (2007).
 * 2) While great in Transformers (2007), he was also great in the video game adaptations as well as being more tolerable in the other video game adaptations of the later two movies.
 * 3) *He also has quite the best and better moments in the video game adaptation of Transformers: Dark of The Moon such as how he single-handedly defeated Optimus Prime on his own.
 * 4) He was also much better in the book versions of the first trilogy of Michael Bay's Transformers movies.
 * 5) His design might be ugly, but it had a lot of effort.
 * 6) *In addition, he's the only Transformers character in the film series whose design changes in every movie which is interesting.
 * 7) Kids may still love him as a villain.
 * 8) He does a fair amount of cool stuff in the movies, particularly in the fight scenes.
 * 9) He does say some cool stuff such as:
 * 10) Transformers (2007)
 * 11) *I AM MEGATRON.
 * 12) *NO, I WANT TWO!
 * 13) *JOIN THEM IN EXTINCTION!!!
 * 14) Transformers 2: Revenge of the Fallen (2009)
 * 15) *EVEN IN DEATH, THERE IS NO COMMAND BUT MINE.
 * 16) *DECEPTICONS, BEGIN OUR ASSAULT!!!
 * 17) Transformers 3: Dark of the Moon (2011)
 * 18) *ALL HAIL MEGATRON.
 * 19) *THIS IS MY PLANET!
 * 20) Transformers 4: Age of Extinction (2014)
 * 21) * THAT IS WHY I HAVE NO FEAR! YOU DIE!!
 * 22) *WE SHALL MEET AGAIN PRIME, FOR I AM REBORN.
 * 23) Transformers 5: The Last Knight (2017)
 * 24) *THE END IS NEAR, MY OLD TREACHEROUS FRIEND. WHAT A SHAME YOU'LL BE UNABLE TO SEE IT.
 * 25) *WE WERE BROTHERS ONCE!
 * 26) Hugo Weaving and Frank Welker did a great job voicing him.
 * 27) The scene where he orchestrated an attempt to remove the brain of Sam from his skull, mentioned in BQ #2, can be considered cool or appropriately intense since it's disturbing and different.
 * 28) The toy versions of him are nice.

Trivia

 * In Transformers (2007), he was originally going to be a tank with a G1-esque appearance. The tank actually appears in Megatron's design in Angry Birds Transformers.
