|Complete the Boss Rush as JudasJudas' Shadow|
Judas' Shadow is an unlockable passive item.
- Grants an extra life.
- Upon death, Isaac resurrects as Black Judas.
- Black Judas has a damage multiplier of 2.00 and a base speed of 1.1.
- Beating bosses as Black Judas will give Completion Marks for Judas and will unlock the associated items and achievements.
- Because Black Judas counts as a unique character, this means that all character-specific qualities are replaced with those of Black Judas's upon death. For example, if the Blue Baby dies and respawns as Black Judas, he will be able to pick up red heart containers. If Azazel dies and respawns as Black Judas, his short-ranged Brimstone will be removed, along with his flying abilities.
- Black Judas has his own loading screen shown when moving to a new floor.
