I would also say that Lockdown and Attinger of the four villains in the film qualify as Complete Monsters. Lockdown because of how he endangered a whole city by dropping metallic objects in an attempt to recapture Optimus Prime, and Attinger because of his willingess to profit off the destruction of Transformers and get rich.
I also agree both villains are monsters but the thing I don't agree with is Lamborghini Aventador here being the "only" main antagonist as Attinger is the lead here being considered a "secondary" despite being more like the main antagonist. Again, do not add Attinger again to secondary as he is no secondary villain. He is the main villain as he plotted everything & started all the events of the fourth film by killing all Autobots consisting of Ratchet & Leadfoot, & possibly his bros. Topspin & Roadbuster as well as Sideswipe, Chromia (if you still believe she survived the events of Revenge of the Fallen), Wheelie (Brains survived the crash so presumingly Wheelie too) & even my really favorite Autobot, the Ferrari 458 Italia for his selfish desire. He even have tried to kill Optimus & Cade & his family for his selfish desire & he doesn't even owe the Autobots about what they have done & I hate his stupid racist character. Lamborghini can't qualify as the main antagonist as he is just following orders from Attinger & the Quintessons, though he still qualifies as a CM.
I would say no to Galvatron and Savoy being CM's. Galvatron was your generic doomsday villain wanting to rebuild his army using the seed. And Savoy was a tragic villain who lost his sister during Dark of The Moon and whose actions although heinous could be traced back to Attinger so they dont quite qualify in my opinion.
The only thing is that most of his actions took place offscreen, nameley his abuse of his son, and that killing the hero isn't heinous enough either. His plan to freeze over the Unova region, while bad, doesn't really prove he's monstrous. The video game doesn't even say that his plan would lead to the deaths of millions of people. It's only fridge horror, which is something that a complete monster cannot have. Again, he is not a complete monster. Don't add him again.
You keep adding the Complete Monster category to villains who don't qualify. When others remove the catgory and explain why they don't qualify, you've been ignoring them and re-adding it. This needs to stop.
Fine I apoligize for doing that, I knew Hyperion as a tragic villain. Losing his Wife and kids to illness and feeling vengeful against the gods. Maybe he has a little honor even if he does not show it. And Galt is a bad egg (I personally consider him a complete monster) he is not as bad as Zaysen or Tint. Those two were gruesomly brutal.
