Top 10 Most Intelligent Sonic the Hedgehog Characters

There are many Sonic the Hedgehog characters who are intelligent. But which Sonic character has the greatest knowledge by far?
The Top Ten
1 Miles "Tails" Prower Miles Prower, more commonly known by his nickname Tails, is a fictional character in Sega's Sonic the Hedgehog series. He is a significant main character after the title character Sonic, who is also his best friend.

Tails is clearly the smartest person on this list. He's a two-tailed fox with a dangerously high IQ that matches Eggman's perfectly. Tails might become the smartest fox alive when he's an adult or the smartest in the universe when he's Eggman's age.

Also, he's linked to the chaos forces, which pretty much makes him more powerful than Shadow. Come on, guys and gals, Titan Tails and Turbo Tails are a thing.

Tails and Sonic Pals, Emerald Masters, Gotta Go Fast, and Charmy Bee have really disappointed me over the years. Did you know that they joke about diabetes? That's messed up. What's next, are they going to mock the dead and dying?

I'm not happy about that. I hate what they've done with the characters, and I sure as hell hate that nasty diabetes joke of theirs. If this is friendship, then friendship is a lie.

2 Dr. Eggman Robotnik Doctor Ivo "Eggman" Robotnik is a fictional video game character and the main antagonist of the Sonic the Hedgehog series, created by Sega.

Doctor Ivo Julian "Eggman" Robotnik truly is a genius with a dangerously high IQ, but he lacks what Tails has: friends and allies, people who truly care about him and see him for who he truly is.

Too bad Tails and Sonic Pals, Emerald Masters, Gotta Go Fast, and Charmy Bee messed this up. Tails is a genius, but their stupidity made him out to be what he is not - an idiot. They are the idiots, not him.

Tails and Eggman are both dangerously minded geniuses. They really need to stop being stupid and write what needs to be written.

3 Shadow the Hedgehog Shadow the Hedgehog is a character who appears in the Sonic the Hedgehog series released by Sega. He is an artificially created black and red hedgehog whose hover shoes propel him at extreme speeds that rival those of Sonic.

Shadow is a smart guy despite lacking the brains that Tails has in spades and the knowledge that Eggman holds. Shadow is just him. Shadow is the ultimate life form, a hedgehog of great power despite not being linked to the Chaos Force like Tails.

Shadow has power, yes, but Tails has all of that and more, way more.

Like Knuckles, his anger gets the better of him. He is too angry to be a genius, but he can still be a genius at times. He just isn't as smart as Tails, and he actually accepted this in the main canon. Unlike Eggman, he is smart enough to know that Tails is a genius.

4 Wave the Swallow

Number four genius. I actually like the idea of Tails being the most dangerous mind on Mobius. Wave is smart, but Tails is dangerous.

The little guy is growing as a dangerous mastermind, which could spell danger if he had his own dark form. Tails would command all of the powers of the chaos force and would pretty much stand as a chaos-devouring vampire. Tails's dark form would be a chaos-fueled vampire that feeds off of the chaos powers of others. Somebody write that as a Sonic-themed vampire story.

Now, onto Wave, the genius thief of the hour/skies. Wave is a genius when it comes to hoverboards and gadgets. Tails just takes the cake and eats it too.

5 Rouge the Bat

I understand why she's not higher. As a kid, it's very easy to overlook manipulative intelligence in a character since it's so low-key, but I think any older Sonic fans can agree that she knows how to get what she wants without her peers even knowing she's doing it. She's like the Littlefinger of Sonic. Let's be real. Tails and Wave may be great mechanics, but they're no strategic geniuses.

How is she not higher? She's one of the smartest characters to ever exist in the franchise. As a spy, she hacks computers and knows what kind of resources are needed to do something. This list is messed up.

6 Blaze the Cat

Blaze's anger makes her not as smart as everybody else, with Tails taking the cake. But she is still pretty smart despite Eggman being the smartest.

I refuse to admit that Blaze is smart because of Tails and Sonic Pals's channel. Bulma Bunny really messed up when it came to voicing them.

Blaze is a bit "hot-headed," but she can be a genius when she isn't angry or past her boiling point. Smart, just not a genius.

7 Sonic the Hedgehog Sonic the Hedgehog, trademarked Sonic The Hedgehog, is the title character and protagonist of the Sonic the Hedgehog series released by SEGA, as well as numerous spin-off comics, five animated shows, and an animated OVA.

In many spin-offs, especially SatAM and Archie Comics, Sonic is shown to have a diverse vocabulary. Although he often uses slang, he also shows knowledge of basic physics and foreign languages (such as Spanish).

He is quite the wordsmith, and his well-roundedness truly shows. His sense of humor, especially in comic spin-offs, also shows his intellect. Additionally, he is sometimes shown to think deeply about himself and his place in his world. He is often the first to say something when times are hard and when everyone needs encouragement or a sweet send-off to a lost friend.

8 Sally Acorn Sally Acorn is a Mobian chipmunk, the daughter of King Nigel Acorn, and the leader of the Freedom Fighters. She is also the heroine of the SatAM television series... read more

The heroes are damn lucky that Tails is on their side because if he wasn't, all hell would flood into Mobius like a plague. Tails would take over both worlds without a problem, and Sonic couldn't do anything to stop him unless he allowed him to travel with him, which he wouldn't. He'd succeed at making the two worlds his, and all hope would fall.

Besides, the only two Mobians that can travel between worlds other than Eggman are Tails and Knuckles. Sally Acorn, on the other hand, is the future queen. She has to be smart in order to rule, which she couldn't have done without Nicole. Nicole is the one that made her the girl she is today. If it wasn't for her, she wouldn't even be this smart.

9 Tikal the Echidna

Tikal is nowhere near the same level as Tails and Eggman, but she still knows the Chaos Emeralds better than anybody.

Tails might still have her beat, though.

Tikal is shown to have a wide knowledge of Chaos energy and even spoke wisely about avoiding greed.

Tikal is wise, yes, but smart, kind of. She isn't as smart as Tails, and despite his flaws, Tails is 100% smarter than her.

10 Silver The Hedgehog

Since he comes from the future, Silver is aware of some very advanced technology that Tails or Eggman can't even imagine. Also, it takes a lot of mental effort to exercise telekinesis, which is impossible for mentally limited people.

He should also have the potential to be one of the smartest Sonic characters ever, next to Tails and others.

Silver is smart. He even knows how to change the past to make the future better.

The Contenders
11 Cosmo the Seedrian

Cosmo is far smarter than everybody else on this list except for Tails, Eggman, Wave, and Shadow. She should at least be number five. Why is Sonic there instead of her?

He isn't smart. He runs into danger, while a smart person would stop and think of a way through. Sonic is not willing to wait for anything. Cosmo deserves the number five spot, not him. She's way smarter than he is.

I think that it would be for the best if Tails stayed with Cosmo on her home planet instead of heading home with his friends. Besides, the UwU universe versions of the characters surely wouldn't care if he stayed with her.

Heck, the two of them could program the ship to take them home before exploring. They could make everyone believe that Tails had been killed in the destroyed spaceship. Not like they would care anyway.

12 Amy Rose Amy Rose is a fictional character in SEGA's Sonic the Hedgehog series. She is a pink anthropomorphic hedgehog with a cheerful, competitive personality, and is infatuated with the series' main character, Sonic. She serves as the first playable female character in the series.

Amy has been my favorite Sonic the Hedgehog character since I was seven years old. I was surprised that she was on this list, but I must say she has made some smarter choices than Sonic.

Though in '06, Amy said, "If I had to choose between the world and Sonic, I would choose Sonic!" That doesn't mean Amy is dumb just because of that one line. Amy is very obsessed with Sonic, but look at her in Frontiers and Prime! She has obviously matured a lot in those, and she deserves better.

Honestly, though I'm the biggest Amy Rose fan out there, I have to say that Sally Acorn is smarter than her. Why isn't Sally on this list? Tails and Sonic Pals Amy isn't very smart, but other versions of Amy are a lot smarter than that one. Everyone needs to understand, Amy is twelve. Of course, she's not that smart yet!

Thank you for taking your time reading this, and carry on with your day.

13 Dr. Gerald Robotnik

I admit that he made Shadow, and that's genius enough, but the main problem with that is that he made Shadow. He created the ultimate life form, yes, but he also created the ultimate wannabe Sonic.

What part of this screams ultimate life form besides Shadow himself? Shadow is powerful, yes, but he isn't as good as anything Tails can create.

Why doesn't Tails create his own ultimate life form and have Shadow face it in a battle to the death or otherwise? Gerald was able to create Shadow with a single chaos emerald. Just imagine what Tails could create through a chaos and sol emerald with a time stone to add an extra punch. Shadow doesn't stand a chance.

Bulma Bunny knows nothing about the characters nor the main canon, seeing that they're too stupid to understand anything about Sonic the Hedgehog.

14 Vector the Crocodile Vector the Crocodile is a fictional anthropomorphic crocodile from the Sonic the Hedgehog series who debuted in Knuckles' Chaotix in 1995, and later returned in Sonic Heroes as head detective of the Chaotix Detective Agency. With a great love for music and money (the latter which he is always short... read more

Ace detective who deduced the entirety of the plot to Sonic Heroes after one interaction. Despite his gangster looks, he's a bit of a Sherlock.

He is a detective and was able to figure out that Eggman was their client in Sonic Heroes.

He isn't as smart as Espio, but he still has his moments.

15 Cream the Rabbit

Cream is alright. She's smart, yes, but she isn't as smart as Tails or even Eggman for that matter.

16 Dr. Eggman Nega Doctor Ivo "Eggman" Robotnik is a fictional video game character and the main antagonist of the Sonic the Hedgehog series, created by Sega.

Doctor Eggman Nega isn't as smart as Eggman and Tails, but he still knows his way around tech and machines just like Eggman himself. Eggman is still smarter, though, and Tails takes the cake.

Eggman Nega is smart enough. Not as much as Tails and Eggman, but still, he is better than nothing.

I think he's not that different from Eggman.

17 Espio the Chameleon Espio The Chameleon is a Sonic character first appearing in the 1995 Sega 32X title, Knuckles' Chaotix alongside Charmy Bee and Vector the Crocodile. Espio's appearance in Knuckles' Chaotix depicts him as a character with a hot temper which causes Charmy to remind him about his manners. In Sonic Heroes,... read more

He might be smarter than Vector.

It takes brains to be a detective, and this guy is the smartest of all the Chaotix.

I think, since he is a detective, Espio might have a good culture, combined with that of a ninja.

18 Knuckles the Echidna Knuckles the Echidna is a fictional character in Sega's Sonic the Hedgehog series. He is a red anthropomorphic echidna who is determined and serious, but sometimes gullible. He has the ability to glide and climb up walls, and is a powerful fighter due to his spiked hands.
19 Charmy the Bee

Vector may be the brains of The Chaotix, followed by Espio, but Charmy does have his moments.

He can be smart, just not on the same level as Tails.

20 Infinite
21 Metal Sonic Metal Sonic is one of Eggman’s fastest and most powerful creations. Programed to be better than Sonic in any aspect possible, he can shoot electro balls, shoot electricity downward, do a boost, and make himself invincible. He fight’s Sonic each time he gets stronger, and when he gains enough power,... read more

He should really be on the same level as Sonic. Even though he is a robot version of him, he needs to be higher.

But he can't because Eggman designs all of his robots to be nowhere near his IQ. He has an IQ. He'll never allow a Grounder to be smarter than him or near his level, for that matter.

However, he admires Tails for his IQ while still being the villain. This tells us a lot about his character and how he views brains compared to his own.

Metal Sonic isn't as smart as Eggman unless he is Neo Metal Sonic, but still, Eggman outranks him while Tails outfoxes them both.

22 Neo Metal Sonic

He can be even more intelligent than Metal Sonic.

Metal Sonic was actually smarter than this guy.

23 Lyric the Last Ancient

Dude has Eggman-level intellect based on his tech. Also, he did that in prehistoric times, so bonus points.

24 Pacahamic the Echidna

What do you want me to say about him?
This guy is pretty foolish if you ask me.

25 Fang the Sniper

Fang was actually way smarter in Sonic the comic then he was in the main canon, but he still has his moments and he still outsmarts Fleet-way Sonic more times than the fans might like to admit; also Sonic kinda killed him at the end of the comic he appeared in, remember true heroes never kill they only kill if they have to and Sonic really didn't need to kill Fang in Sonic the comic.
Besides, I actually kinda liked the guy which was mainly due to the fact that his a hybrid and I love those types of characters enough said.
