Jack Kline

Jack's natural form is mainly that of a Caucasian teenage human boy including wavy dark blond hair, vibrant green eyes and very fair skin.

Jack's eyes glow yellow-gold; they often do so when Jack uses his powers.   Jack has also been shown with a large pair of angelic wings, which seems to be as big as those of Archangels.

Astral Projection: Jack can show his wings. Jack emitted a high pitched ringing sound after he was born, like Lucifer does in his true form.   Chronokinesis: Jack was able to freeze anyone for a few seconds when they lie to him.   Eye Transformation: Jack could turn his eyes gold when using his powers.   Banishing: Jack managed to effortlessly banish Onis back to Koronga.   Biokinesis: Jack has displayed the ability to absorb, assimilate and dissolve organic and inorganic objects.   Supernatural Perception: Jack could perceive the true form of angels without any ill effects.   Electrokinesis: Jack's labor caused a power outage. In his normal state, he also able to affect the works of machinery and electricity. When scared, he also can cause electricity to go haywire.   Healing: While empowering Castiel, he also healed the angel's injuries in a manner of seconds. He later healed Sam's serious head injury from an orc bashing his head in with a rock.   Illusion: To entertain some kids, Jack was able to alter the shadow puppet shapes he was making to look like whatever he wanted.   Photokinesis: When Jack was born, his birth caused him to emit a yellow blast of light that briefly knocked a nearby Cas unconscious.   Power Granting: Jack was able to temporarily empower Castiel.   Pyrokinesis: Jack burned a weretiger to death from the inside, leaving the outside of its body scorched.   Thermokinesis: After Jack was born, his footprints scorched the parts of the floor.   Salt Transmutation: Jack was able to transform a human into a pile of salt.   Soul Manipulation: The raw energy of Jack's soul fully magnified was capable of vaporizing multiple hellhounds into dust.   Spell Casting: Jack has the ability to cast powerful spells.   Terrakinesis: When Jack got angry at Asmodeus for harming the Winchesters and Cas, his anger caused the ground to shake for a moment.   Telekinesis: Jack was able to send out powerful blasts of telekinetic energy strong enough to knock two people unconscious at once. When Jack did this, visible waves of energy emanated out of him.   Telepathy: Jack showed the ability to telepathically call out to Castiel.   Sedation: Like an angel, Jack can put a person to sleep with just a touch.   Empathy: Jack was able to sense the pain of Jesse's who was in a diffrent part of Nightfrost before confronting him.   Teleportation: Jack displayed the ability to teleport after being upset by a conversation and wanting to be away from it.   Super Stamina: Jack once stated that he does not sleep a lot, but unlike an Angel, he still requires sleep. It is also implied that Jack may not need oxygen.   Super Strength: Jack wields enormous levels of superhuman strength that is clearly far above any Nephilim before him.   Supernatural Concealment: When Jack does not want to be found, his powers are subconsciously concealing him from other beings which was shown by the fact that Asmodeus, Lucifer and everyone else who were looking for him were incapable of tracking his whereabouts. This is notable considering how his immense power usually makes him very easy to locate.   Nigh-Invulnerability: As the one of the strongest Nephilim Spawn, Jack possesses complete invulnerability to almost any harm. Unlike other Nephilim, Jack is completely invulnerable against an angel blade even when being stabbed in the heart with it.   Immunity: Despite his angelic heritage, Jack is immune to angel banishing sigil. However, the sigils do have an unseen effect on him, causing him pain and making golden marks appear briefly on his veins. He is also immune to most angel warding though being inside a building with very powerful warding can dampen his abilities.   Regeneration: He was able to easily remove an angel blade from his chest and the wound quickly healed in seconds. After Jack stabbed himself several times in the chest with a butcher knife, his wounds healed in mere moments.   Proficient Hunting Skills: Jack has learned a level of hunting skills from his time with the Winchesters, an example being that he has learned how to research for cases which he stated was from watching them do it themselves.   Skilled Hand-to-Hand Combatant: James Gordon taught Jack some basic boxing techniques. He was also able to tackle a Tormentor off of Sam and restrain him for a time. However he lacks proper training like Sam and Dean and similar to Crowley, mainly uses his powers to give him the edge in a fight.   Intelligence: Despite having quite a naïve personality, Jack has proven himself to be very intelligent on occasions.   Intuition: Jack has shown himself to be quite intuitive. From the womb, he was able to instinctively tell that Castiel could be trusted after feeling him touch Jack's kicks. Jack even stated that he remembers feeling safe at that very time.   Adaptability: Jack has shown himself to be highly adaptable to certain situations.   Energy Blasts: Jack was able to emit powerful blasts of energy able to knock Jason off of his feet.   Healing: After Castiel was poisoned by Slitherwing venom, Jack used the power of his soul to heal him when the anti-venom didn't work.

Angel Blade: Angel Blade is a weapon carried by most Angels. It is long, silver, triple-edged daggers (cross section of the blade would be a triangle) that can be used to kill Angels, Nephilims, Hellhounds, Demons, Werewolves and other supernatural creatures. However an angel blade can only harm but not kill an archangel.
