Hello everyone!!
I don't usually make articles like these, but I'll do my best to make sense of the topic I've been wanting to discuss for a while now.
I know I shouldn't be questioning the common sense or intelligence of fictional villains like the minds of real people, but I was also curious to look more into the writing and logic behind fictional villains in how they think and act, specifically those who are really arrogant or egotistical as people. Before discussing this, I've made sure to remember that there have been many works of fiction that do make it fully clear and well-established how smart many villains tend to be at manipulating others, displaying if they're genuinely intelligent people or not, as well as seeing how other people analyze these villains and reminding myself of the rule in the Masterminds category for how they can be classified as "incompetent" if they meet the criteria and how arrogance can be exploited quite often. (like how Sheldon J. Plankton despite being prone to anger, being childish sometimes, having many moments of ignoring the fact Karen came up with smarter decisions than him or Plankton making one foolish plan in "Plankton Gets The Boot", Plankton is still a genuinely smart person to be categorized as a "Mastermind" or how AOSTH Robotnik genuinely has such a huge ego that he can lack some common sense and have an immature mentality despite being a self-stated "genius" scientist; the reason he's categorized as a "Dimwit").
When I look into the minds of fictional arrogant villains that are categorized as "Masterminds", certain behaviors from the most iconic of these villains have shown, despite their talents as geniuses and villains, make me wonder at times: "If they really are evil masterminds, and their continual arrogance and pride make them do irrational or foolish things with cheap excuses to justify their plans not making sense or being likely to fail all the time, either done humorously or for the story; are they really wise and have outstanding intellect as they claim to have or are they just strategic Dimwits with delusions and superiority complexes?" (Or if they SHOULD have their own category titled "Genius" in the same way the Hero version and Villain Fanon version already have, especially if certain villains on this wiki that are categorized as "Masterminds" have done some foolhardy actions without thinking clearly and show certain behaviors that reveal that they aren't as clever, smart, or wise as they seem to be, especially if they are absolute egotists!).
I ask to debate this because some comedic villains listed as Masterminds that come to mind like Wile E. Coyote and Dr. Eggman, in terms of how they're written, are made out to be evil geniuses whose talents make them out to be really brilliant and formidable people with fun traits as the story presents to us. However, in terms of story, I have noticed that the two seem to have some inconsistencies to them in some instances like Wile E. Coyote in the "New Looney Tunes" series or some of Eggman's worst machines/worst ideas throughout the Sonic series that appeared on many "top 10" lists on YouTube, have made me question their statuses as "Masterminds" (especially Eggman).
The Wabbit incarnation of Wile E. Coyote has shown to exaggerate his traits of smugness and arrogance towards Bugs Bunny, which has gone to the point where he was considered to be not so smart by Bugs one time in the episode "Coyote.Rabbit.Squirrel". Especially when this version of Wile E. needlessly brags/boasts so much about the inventions he makes as seen in several episodes like the episode "Leaf It Alone" for example, using bad excuses or wordy language to hide the fact he was wrong about constantly relying on technology for solutions as seen in the episode "Bugs in the Garden", how he couldn't fix his own simple problems without someone like Bugs doing it for him as seen in already mentioned episode "Coyote.Rabbit.Squirrel", and has shown to be too lazy/useless without technology doing things for him in the episode "Appropriate Technology". Because of these reasons, I'd argue that the Wabbit version of Wile E. Coyote appears to have some dimwitted qualities in terms of egomania and delusions of grandeur because Looney Tunes has already established that even though Wile can sometimes make stupidly overcomplicated plans or show some delay in harm coming his way; Wile is proven to be a genuinely smart and talented person regardless of irony, blunder or constant misfortune), especially in the classic shorts when Wile E. Coyote interacts with Bugs, he always maintained many intellectual qualities that make him an intelligent villain like knowing the trails of a rabbit's foot, having a poetic speech pattern, one time discussing how Bugs would've outsmarted him and coming up with creative plans despite being completely incompetent and sometimes misguided because of how incredibly smug and arrogant he is.
For Eggman's case, it has been evidenced that there are many online reviewers have noticed how Eggman's worst machines throughout the Sonic series, certain decisions he's made in the series, one reviewer pointing out that anyone with an I.Q past 200 would understand how world conquest is totally pointless to do, and at least one video showcasing his inefficient traits in terms of failing to defeat Sonic the Hedgehog even beyond analyzing every single boss fight Eggman has provided (ex. asking how Sonic caught up to him showing an oblivious moment of his and the fact Eggman didn't think that launching Werehog Sonic WITH the chaos emeralds was a hasty decision that Eggman rationalizes the excuse being that it was an intentional mistake to create a challenge for his plan in "Sonic Unleashed"); all of which have made several people see Eggman as a fool or a goof despite being a technological genius with a 300 I.Q.
It doesn't help that in some articles I've seen on this wiki like the Dave the Intern article, I originally saw the page having both categories "Masterminds" and "Dimwits" on the SAME page, I looked more into the character, and he is not a dimwit at all and more of a nerdy basement-dweller for a villain whose behavior is often played for laughs. For as illogical, unlikely, and ridiculous as this may sound, this is why some dimwitted villains in fiction could also be Master Manipulators or Tricksters if they're manipulative and evasive enough to succeed or cause problems but still happen to be unintelligent people in general.
When I looked into the Boom Eggman article, he was categorized to be a "Mastermind" for some time, I changed that and put him in the "Dimwits" category instead because his intelligence and common sense always go "on and off" in all 2 seasons of Sonic Boom, with his foolish traits appearing more often than his smartest traits. Ever since the first season, he switches from being a tech-savvy mastermind with a deceptive yet incompetent and childish streak to being self-aware and having his smart/cunning moments in episodes like "Hedgehog Day", "The Meteor", "Multi-Tails", and "Can an Evil Genius Crash on Your Couch for a Few Days?" for example, to becoming more and more of an extremely silly manchild with the personality of a teenager who doesn't know how to use a normal bowl in the episode "Eggman Unplugged", thinks horror-movie ghosts are real in the episode "The Haunted Lair", stupidly revealed his own evil plans on public broadcast without knowing in the episode "Dr. Eggman's Tomato Sauce", and was so inexplicably gullible he thought an obviously fake Sonic doll was the real Sonic in the episode "Sticks and Amy's Excellent Staycation".
This is why I feel like discussing with everyone on this wiki if there should be a "Genius" category at all. Feel free to share your thoughts with me on this! And again, I could be looking way too much into this, I'm very sure the minds of dimwitted villains are obviously diverse from actual masterminds or even delusional villains.
