Their intelligence (Intelligence Quotient – IQ) can not be measured by any kind of measurement:
1/ Ekko:
He is well-known with the title “Prodigy of the Zaun”, Ekko showed his genius in a creative and imaginative mind since he was just a little boy, at the teenage. Engine Z – A device which can easily manipulate the time line is the most attentive invention that has ever created by Ekko as a solid proof for his high IQ.
It takes Zilean for an entire life to learn the magic spell which can manipulate time, but with Ekko, only a short period (few years) that he need to master it (despite his skill is not so equivalent to Zilean in some cases, but he still catch up with the formula to engage the magic).
2/ Heimerdinger:
His real name is Cecil B. Heimerdinger. The name has been known for the greatest genius inventor of Piltover. Thus, we can imagine how smart he is and what does a big brain can create. His deadly weapons – the machines that make tons of enemies pass away in just a blink of an eye is the result of his whole life researches and magnificent science demonstration.
With an enormous head (may contains a lot of brain cells) and the name that is the combination between Robert Oppenheimer and Erwin Schrödinger, Heimerdinger’s IQ can be told to be higher than other Yordle in the realm. What a “master of mechanic”!
3/ Jayce:
As a citizen of Piltover’s tech kingdom which is known as a paradise of technology in general, young Jayce even soon became famous for his inventions, alongside his spirit of chivalry. The transformation hammer made from Hextech technology is an iconic product by Piltover, with all the finest features of patent technology embodied in it.
However, because he was aware of the dangers that threaten the city, Jayce temporarily put his passion for invention aside to focus on a job that requires less brainpower, but requires noble spirit and enthusiasm. So that, he is determined to be a person – The Guardian of Piltover.
4/ Viktor:
Compared to the three names mentioned above, Viktor is even more genius than anything else. He was the one who invented Blitzcrank – A machine with perception like living beings, and even, already close to the level of science that could evolve humanity to new heights (at least that’s what he thought ).
By transforming himself into a form of biological robot by replacing body parts with machines, Viktor can be said to possess a great stature of intelligence, but his insanity turns super intelligence. This unbreakable and full of madness becomes a formidable weapon, even capable of determining the fate of both Zaun and Piltover.
5/ Rumble:
Unlike the names mentioned above, Rumble is probably on a different level, because he does not have adequate financial support and materials for research, but all Rumble’s inventions are by hand. he created.
The Tristy machine – Rumble’s lifelong pride was actually only born from the scrap yard, with the redundant parts thrown away, but through the talented hands of this Yordle, they turned into a dance the gas has terrible destructive power.
Even, Rumble is admirable in that, he is completely indifferent to inventing or researching like the four names mentioned above (the most important thing in his life is probably Tristana), but he is capable of giving out. Lifetime of inventions showing intellectual stature is not inferior to the 4 of them.
Generally speaking, the top 5 above can be considered to be the smartest champions. They are not the most muscular, but their brains are so muscular than any other opponents.
