Who he is: Lincoln Campbell
His power: Lincoln is an Inhuman who possesses the ability to manipulate electricity.
His story: In his earlier life, Lincoln Campbell suffered from depression and was prone to fits of anger. After nearly killing his girlfriend one night by drunk driving and hitting a telephone pole, he was brought to the Inhuman sanctuary Afterlife by the eyeless teleporter Gordon, where he discovered his powers and learned to control them. After trying to do the same for Daisy Johnson, Lincoln was initially on Jiaying’s side in the Inhuman struggle against S.H.I.E.L.D., but switched allegiances and helped defeat her after watching her murder innocent people. He then tried to work incognito in a hospital, but was forced into hiding when the Inhuman killer Lash came after him. He subsequently began training to be a S.H.I.E.L.D. agent, but eventually refused the offer when Phil Coulson offered him a spot on the team. However, he formed a romantic relationship with Daisy, and sacrificed his life to save her, along with the rest of the world, by taking a S.H.I.E.L.D. craft containing Hive and a nuclear weapon up into space, where it detonated, killing them both.
