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.

Why He Sucks

 * 1) Megatron has a blank personality 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 when using that name because in Transformers 5: The Last Knight, he became "Megatron" again.
 * 5) Back to Transformers 2: Revenge of the Fallen, he barely uses his tank mode at all and just to sell toys!
 * 6) He looks ugly for a Decepticon.

Redeeming Qualities

 * 1) He was not as bad in Transformers (2007).
 * 2) His design might be ugly, but it had a lot of effort.
 * 3) Hugo weaving did a great job voicing him.

Trivia

 * 1) In Transformers (2007), he was originally going to be a tank with a G1-esque appearance.
