Smartest Dragon Ball Z Characters

Invented the dragon radar and a time machine.

Besides having the combined knowledge of the two ancient beings King Piccolo and Kami, he also has all of the Namekian knowledge of Nail and his own earthly experience. With the combined intellects of at least 4 individuals and the time he spends alone in meditation, Piccolo is nothing short of a genius. Its his strategic mind that has saved Goku and his friends on a number of occasions. If he wasn't so focused on martial arts mastery, who knows to what ends he could put his mind?

An earthling that was able to create Androids that were even more powerful than aliens like Frieza. He was even able to turn himself into an Android. And created a biological being that consists of DNA acquired from the most powerful warriors in the universe. That's brilliant.

Gohan doesn't lack experience in battles, by 11 he surpassed his father and became, at that time, the strongest in the universe as buu was still dead or locked away and he even took on buu as well becoming the strongest unfused character in dbz as ultimate gohan. Also at 6 he went up against frieza, who was at the time undeniably strong, his name was enough to completely scare king kai and owned a galactic planet control organisation. At the time of the namek saga, nobody, not even vegeta would dare go up against him but yet he fought him took him down, before frieza went into his stronger form. Taking on cell, frieza and buu, being the strongest in the universe twice, ultimate gohan and super saiyan 2 gohan, I think that qualifies as the highest level of experience in the universe, even if in between cell and buu, he started to slack off a bit. He is very good academically and considered a genius, as well as being battle smart and being the captain for the winning team which is ...more

He can do Mathematics with ease and he could've possibly learned Multiple Languages while he was a kid, maybe Planet Vegeta has a different official language. You never know how he successfully learned how to speak Earthling?

He's very tactical and is a brilliant strategist, though his pride does blind his judgement at times, which results in his making false decisions.

He has 300 years' worth of experience. That's saying something.

He is a nigh-omniscient being enough said.

He is an angel who's probably been around for a long time, way longer than any of the people on this list, other than shenron, there is no one who rivals him in this category.

Whis and any of the other angel seem to be highly intelligent they already know stuff before most character realize anything. They are always having to explain things

He is a very good strategist and is fairly experienced and innovative during fights.

As experienced as Goku, but more innovative.

He IS the smartest when it comes to fighting, being able to outsmart even Piccolo at times. He always comes up with the best training methods, almost never makes false move, and is overall a brilliant strategist. His ignorance of academic knowledge was due to the fact that he spent his childhood in the forest without going to school. He also has the ability to learn things really fast, not just in battles but also in other things like driving a spaceship,.etc.. According to Dragon Ball Wiki, " He has a simple, practical view of the world that often comes off as naïve, which often makes many incorrectly assume him to be somewhat stupid. While often taking things to face-value, he comprehends the situation quickly and learns the basics of anything presented to him rather quickly. To which, he is repeatedly proven a very effective tactician, quickly see through his opponent's strength and battle tactics to formulate an effective countermeasure.
