Twilight: The Reason For Bella’s Vampire Control Mirrors Jasper’s Weakness
The vampires in Twilight had different powers, but a fan theory suggests that their weaknesses were also magnified with their transformation.

The Twilight books and movies introduced the audience to a one-of-a-kind type of vampires, and each one of them has a special power based on their strongest trait as humans, but a fan theory suggests that their weaknesses are also enhanced, which explains Bella’s self-control and mirrors Jasper’s weakness. Back in 2005, Stephenie Meyer shared her unique vision of vampires and werewolves in her debut novel Twilight, the first entry in a series of four books chronicling the problematic romance between mortal Bella Swan and vampire Edward Cullen.
The Twilight book series became a worldwide phenomenon, so naturally, it didn’t take long for Hollywood to set its eyes on it. The Twilight novels were adapted into a movie saga between 2008 and 2012, with the final book, Breaking Dawn, divided into two movies. The Twilight Saga expanded the books’ fanbase and brought fans closer to the characters, but it also highlighted the series’ weaknesses and plot holes, while also making way for various questions about this universe and theories on the different creatures living in it, especially the vampires and their powers.
The vampires of the Twilight universe are very unique: they tolerate sunshine but their skin sparkles under it, they can’t be killed by traditional methods, their eyes change color depending on whether they are hungry or fed, and they all have superpowers, which are divided into passive and active. A vampire’s powers are the result of the enhancement of their strongest trait as a human, which is why Edward can read minds (as he could “read” people before he was transformed) and Carlisle is very compassionate, this one being an example of a passive power. Now, a fan theory suggests that those traits are not the only ones that are heightened during the transformation, as so are their weaknesses, which explains why Bella was so controlled during her newborn phase.

A now-deleted post on Reddit suggested that a person’s weaknesses were also heightened after their transformation into a vampire in the Twilight universe, and Bella was repulsed by blood, to the point where it made her sick, and she even mentioned at one point (while still a human) that she could smell it. Bella was incredibly self-controlled during her newborn vampire phase, and the theory explains this was because her aversion to human blood was magnified during her transformation. This theory applied to other vampires makes Jasper a dark mirror to Bella, as he was the opposite of self-controlled as a newborn and before he met Alice, and even as part of the Cullen coven he lost control when Bella accidentally cut her finger in New Moon. This was the result of Jasper’s past as a soldier, so his “bloodlust” translated into little self-control as a vampire.
Some fans argue that Bella was so good as a newborn because she made the decision to be a “vegetarian” before she was transformed, so it was all about her strength, a trait that she carried into her life as a vampire. The theory of a person’s weaknesses being enhanced when transformed into a vampire in the Twilight universe is fun and interesting, and in the end, as it happens with many fan theories, it’s up to each fan to decide if the theory makes sense and fits the story or if it’s just a fun interpretation.
