I'm in agony. I can hear my tumors growing!

Colin Phelps was a human turned vampire by Caroline when she was trying to find a cure for her mother's cancer. Unfortunately, the vampire blood sped up his cancer and he was mercy-killed by Damon. Colin proved that cancer is incurable by vampire blood, even after dying and turning into a vampire.

Throughout The Vampire Diaries SeriesEdit

Season SixEdit

In Woke Up With a Monster, Caroline visits him and from his medical charts knows that he's in the same position as her mom health wise and that he has no other family to look after him. She gives him her blood so he at least have comfort while it takes away his cancer. After that, he goes to the vending machine and feels pretty happy and excited in getting his appetite back while Stefan and Caroline watch him from down the hall. Later that night, Colin suddenly dies when Caroline's blood speeds up his cancer and begins his transition as a newborn vampire.

In Prayer For the Dying, he finds Caroline and stumbles into her house during the night. She and Stefan discover he's now a vampire with Jo commenting that his cancer is now at level 10 which is unheard of. Caroline and Stefan find him when he attempted to commit suicide by stabbing himself, but since he was a vampire, the wounds that he made already healed. Before Caroline tries to do anything to help him, he begs Caroline to kill him since she was the one to turn him. Damon granted his wish instead and ended his life.

  • He is also the second unintentionally turned vampire by Caroline's blood. The first was Jesse.
    • Like Jesse, he is also an African-American decent.
    • He still had cancer in his body even though he was now a vampire so Damon kills him to put him out of his misery.
