New World, Dressrosa.
After learning that his friend had been framed, Ace hurried to Dressrosa. His goal was naturally to drag out Doflamingo, the mastermind secretly manipulating the Kingdom of Prodence!
You could say Ace had a brain, but not much of one. His recklessness and hot-blooded nature were practically no different from Luffy's!
Although compared to Luffy, who had absolutely no brains at all, Ace had a little more sense, but really, not much...

The moment he entered the New World, he wanted to challenge Whitebeard. In the end... well, he became Whitebeard's son...
Later, he ignored Whitebeard's warnings and insisted on hunting Blackbeard down. He chose to fight without even investigating Blackbeard's background properly. Whether it was confidence in himself or underestimating Blackbeard, it all came down to one thing: recklessness!
In the end, he was defeated by Blackbeard, which led to the Paramount War...

Ace did not have the strength to cover his own mistakes, so everything could only head in the worst possible direction.

As Dressrosa's current king, Doflamingo had governed Dressrosa very well and was deeply loved
