Karn (Post-Mending)

Karn's powers and abilities

Neowalker - Karn is a Post-Mending Planeswalker, allowing him to freely travel through the Blind Eternities to other planes without being erased from existence. His Spark also grants him immunities to various corrupting effects and raises many of his base resistances and gives him a much greater mana pool than any average being. Because he was a Planeswalker before the mending, this mana pool is even larger than a normal Neowalker, which is further enhanced by him having inherited Urza's spark. Planeswalkers also possess the ability to summon mana duplicates of allies they have made throughout their journeys, an ability Ajani makes heavy use of.

Urza's Master Piece - Karn was constructed by Urza initially to serve as a being capable of traveling through time with no ill effects. His original silver body is nearly indestructible and inside of it are Xantcha's Heartstone, the Weakstone and the Mightstone. The Heartstone gave him his sentience and the twin stones give him immense power over the world around him, allowing him to empower and weaken almost anything.

Metal Magic - Karn primarily utilizes colorless magic to power and create artifacts and machines (although he can use all colors of magic). He is able to pull and create metals out of the aether and make any device he can imagine. Karn is also able to time travel at will among a litany of other abilities.

Karn's weaknesses

Pacifist - Karn is a staunch pacifist and will not get into a physical confrontation unless he absolutely has to. This unwillingness to fight can cause him to hesitate when action is needed.
