Where did Haiqi come from in The Meg 2?

The Meg 2: The Trench. During the events of the first film, Meg gives birth to an albino cub, Haiqi, fathered by her partner. Some time later, Haiqi is captured by Juming Zhang, who adopts the cub and raises it in a sanctuary in Hainan, run by Juming's company.
Why did Haiqi become more aggressive?

Haiqi became more aggressive in The Meg 2 because he grew up in the wild in an underwater trench, where he had to fight for survival. His behavior was shaped by his hunting instincts and he was never domesticated. Unlike the first film, where he was kept captive and fed, in the sequel he lives freely and is the apex predator in his ecosystem.
Wild Environment: In the first film, Haiqi was a cub raised in a sanctuary. After the events of the first film, he returned to his natural habitat in a trench, where he was forced to hunt and fight for survival.
Freedom and Instincts: Unlike the first film, where he was kept in captivity, in the second film, Haiqi was free and lived by the laws of nature. His behavior was shaped by the predatory instinct, which strives for survival and dominance.
Lack of Domestication: He was domesticated in the first film, but was left to his own devices in the second. Consequently, he reverted to his natural, aggressive, predatory behavior.

General description: These are giant sharks that live in the "Bottomless Trench." In the film, they emerge to the surface when the rift that held them in widens.
Size: The Megalodons shown in the film are enormous in size, but their actual sizes, like those of the other Megalodons in the film, are fictional.

Danger: In the film, megalodons are very dangerous and can attack people and ships.
