The most anticipated Jurassic Park sequel will hit theatres in June, featuring its meanest attraction, dinosaur Indominus Rex.

Attention: Potential spoilers ahead, proceed at your own risk.

As we already know that the main villain of Jurassic World would be a genetically modified Dino made of a fatal mix of DNAs – to make the park more popular – ends up inviting more trouble instead. The DNA includes a mix of Carnotaurus, Giganotosaurus, Majungosaurus and Rugops.

But a new plot theory suggests that a human DNA was included while making the Indominus Rex.

Check out the tweets below:

Another fan has posted a picture of the Dinosaur, which apparently has "prehensile hands" and fingers, and speculates that the big bag Dino might have human DNA.

Meanwhile, Movie Pilot has also speculated the same and supports its case stating that the big bad villain could have a human DNA incorporated.

The website states that the original idea for the reboot was human-dinosaur soldiers, but the idea was scrapped because the part-human part-dino soldiers made a rather ugly creation.

"This might not convince you but the original writers for this plot insist on having their names in the credits, meaning they must have had some input on the storyline... Is there still human in the hybrid?" speculates the website.

Another argument is that the I-Rex shows problem solving/planning capabilities in the trailer, which could be hidden clues, that the writers are trying to teases us with the possible human DNA angle.

"With this kind of intelligence and forward-thinking, there's no way she's just made up of a few old random dinos?" speculates the website.

Even in the trailer, it has been clarified that she is an intelligent animal. The I-Rex was able to remove the tracker installed in her when she was young, hence being intelligent enough to know what it is and ambush the men tracking her, is yet another sign of human intelligence in the beast.

But here is a new twist: What if the human DNA used in Indominus Rex is of Chris Pratt's character?

Pratt plays Owen Grady, who is a "Dinosaur trainer" and tames and works alongside raptors at the park.

In previous Jurassic Park movies, we have seen the lead actors being chased by the dinosaurs, but at the end manage to escape the wrath of the beasts. Since, the storyline has mostly repeated in the earlier movies, the new Jurassic World might feature a new element of surprise. As the video says, "They need a new attraction, one that's bigger and badder than the T-Rex."

Moreover, the fact that Owen "works and controls" the raptors, one can speculate if his DNA could indeed have been used in giving life to the animals as this would make it easier for him to train it.

This also explains why Claire (Bryce Dallas Howard) who created the Indominus Rex, feels guilty in the promo video. In the new promo, it has been confirmed that she was romantically involved with the "dino trainer" and she is seen seeking advice about the new Dino she made in the lab from him.

She could have sneaked Owen's DNA, while making the I-rex in lab?

Director Colin Trevorrow had earlier revealed a little about Chris Pratt's character.

He told IGN, "[Pratt's] a classic hero in a very modern context. He's the guy who will get you through the jungle alive – but like Malcolm, Grant and Sattler, he's an expert in a scientific field that's connected to our story. The character allows us to explore some new ideas about our relationship with these animals, without losing the humor and sense of adventure."

All in all, these are just speculations and the final truth about the Indominus Rex DNA will be revealed after the movie premieres on 12 June, 2015.
