After spending months in the Empty, Jack is resurrected by Billie once God left the Earth. Billie provides Jack with a plan that would enable him to become strong enough to kill God Himself.
Billie resurrected Jack and sent him to Earth to feed on Grigori hearts in an effort to make him stronger so that eventually he'll be able to fight Chuck. He would have checked in with Cas and the Winchesters sooner, but he needed to lay low so that Chuck, who fears him, wouldn't find him and kill him again.
During his time with the Doctor, Jack matures into a hero, and in his final 2005 appearance, he sacrifices himself fighting the evil alien Daleks. Rose brings him back to life while suffused with the power of the time vortex, but when the power leaves her she doesn't remember doing it.
Though he was resurrected a second time with no soul, Jack's soul was subsequently restored by the Garden of Eden after he journeyed to it through the Occultum. Lily Sunder agrees to help resurrect Jack using her magic, but tells Sam, Dean, and Castiel that it will use part of his soul in process.
In Ouroboros, Jack absorbed the Alternate Michael's grace returning him to full power, although he had to burn off his entire soul in order to kill him. When his powers were restored, Jack displayed his full angelic wings to show he was himself once more.
In The End, Jack Became A “Hands-Off” Deity
Jack sucked up all their power and he was the one to kill Chuck, and take all his power too. He was more powerful than God and Amara together. He put the whole world to rights but didn't bring back all the people that had died because of his plan.
As CinemaBlend reported, Jack-Jack appears to have an unlimited list of abilities, including laser eyes and combustion inducement, which are two abilities seen in the “Incredibles 2” trailers. “Incredibles 2” director and writer Brad Bird said Jack-Jack doesn't have unlimited gifts, though.
Jack says he snapped and it was over quickly. He wishes it didn't happen. Dean is barely holding it together. He doesn't like that Jack is calling Mary's death, “the accident.” But he plays along and says they understand and they forgive Jack.
Dean later admits to Sam that he misses Jack and doesn't correct Bobby Singer when he calls Jack Dean's kid. This suggests that ultimately Dean forgave Jack and has come to see the young Nephilim as his family once again.
Taking him for a spin in the Impala and showing him the basics of living life for a day are all sensible things Dean does to help Jack acclimate. Also, when Dean listens to Jack's soul-rejuvenating revelation of unintentionally killing Mary, he actually listens and forgives "the kid."
Jack was shot by a Dalek and then brought back to life by Rose, Rose couldn't control what she was doing so she brought him back to life forever, Jack is now immortal.
At the end, Jack coughs up blood in front of Dean before suddenly collapsing, bleeding from his nose and mouth. Rowena determines that Jack's condition is a result of his human and angel sides attacking each other without his grace maintaining a balance.
Over his (very) long life, Captain Jack Harkness has been many things. Revived and made immortal by Rose Tyler after she'd absorbed the power of the Time Vortex, Jack travelled back to 1869, where his vortex manipulator burned out.

Once God has left the Earth, Billie approaches Jack in the Empty and resurrects him to kill God. As the first step in her plan, Billie directs Jack to go after the surviving Grigori -- fallen angels preying on humans -- in order for him to consume their hearts in order to become stronger.

He is the first and only known Nephilim to be sired by an Archangel. Jack was taken in by Sam and Dean Winchester who would teach him how to master his powers. During this time, Jack played a role in the resurrection of Castiel who he had chosen as his father.
In the end, Dean (Jensen Ackles) went out the way he always thought he would: Hunting. He was killed in the series finale while taking on a nest of vampires, but his ultimate end would come in the show's final moments, when he was reunited with Sam (Jared Padalecki) in heaven.
And it left Jack as the new God, in harmony with the Darkness and present in every person and thing on earth. Jack's final speech to the boys was really beautiful, and I love the idea of him as a new God.
When Jack killed Mary Winchester, he sought to redeem himself by creating new angels but it didn't help and he was locked away by the Winchesters. Jack escaped and roamed Earth before he was confronted by the Winchesters who intended to kill him but stopped.
After all, despite his intentions, Sam did the unthinkable. He betrayed him for a demon. Dean tried to see past it and focus on task but the hurt was too deep and the betrayal too raw. He couldn't forgive.
Azazel eventually comes across Mary Campbell, the future mother of series protagonists Sam and Dean Winchester. After taking possession of her father (Mitch Pileggi), he kills her mother and stabs himself to kill his host. Mary's fiance, John Winchester, is the demon's next victim.
Violet is also the only member of her family to have bluish-black hair; her father, mother and younger brother each have blonde, brown and blonde hair, respectively. Bird explained that Violet's hair color is the result of a recessive gene. Violet's hair required animators a total of six months to fully render.
Despite being the youngest member of the family, Jack-Jack has the widest array of superhuman abilities, most of which are centered around shapeshifting. Edna Mode classified Jack-Jack as a polymorph, likening his many powers to him being a baby and thus having limitless potential.
Writer-director Brad Bird said in an interview with The Verge that the way the first movie left the question of Jack-Jack's powers gave the sequel huge payoff potential: “I knew that the audience knew Jack-Jack had multiple powers, but the Parr family did not,” he explains.
