Bella Swan has a notable scar on her arm primarily from a vampire bite she received early in her adventures within the Twilight saga. This distinctive mark is a permanent reminder of a crucial event that shaped her destiny.
This specific bite-mark scar appeared in the first Twilight movie. While she was bitten by a vampire, Edward Cullen intervened quickly to prevent the venom from fully transforming her into a vampire. Despite his successful efforts to stop the spread of the venom, the intense bite itself left a lasting scar on her arm. This scar remained visible on Bella's arm throughout the series, serving as a constant reminder of her brush with vampirism, until she eventually became a vampire herself.
This physical mark underscored her unique connection to the supernatural world and her narrow escape from an early transformation, a testament to Edward's protective actions.
