The Green Door is a metaphysical barrier between the Multiverse and the Below-Place, keeping the malevolent deity known as the One Below All trapped. When killed, the souls of Gamma mutates pass through it into the Below-Place, though they possess no memory of this following their resurrection.
Even when the Green Door is closed, the One Below All is able to exert its influence through the mutagenic form of Gamma radiation, transforming those affected into Gamma mutates that it can potentially possess. The Green Door was partially opened by the detonation of a Gamma Bomb at the Los Diablos Missile Base - turning Bruce Banner into the Gamma mutate known as the Hulk.
When viewed from the outside the Green Door appears as a glowing green rectangular space in a field of darkness. From within the Below-Place, it appears as an enormous pillar of green light.
