Adam is the alternate reality counterpart of the bio-mechanical demonoid known as Adam. Adam existed in the First's hell dimension and was chosen as one of the First Evil's champions for its challenge with Ethan Rayne. In the hell dimension, Adam resided within the Initiative, guarding Cassandra Rayne's leg. After Spike deactivated the other bio-mechanical demoniods with the Initiative's mainframe computer, Adam appeared to challenge him, summoning the walking dead to aid him in fighting Spike. To defeat Adam, Spike had to hit him with an EMP grenade while Adam was holding a barrel over himself, causing Adam to drop it on himself and be damaged. After being hit five times like this, Adam died and Spike got Cassandra's leg.
