Satan is regarded by the Christianity and various religious groups as the supreme overlord of the hierarchy of Hell or alternatively as a living embodiment of evil whose power is second only to that of God and faith - although Satan is a Christian concept almost all orthodox religions have an evil godlike (or semi-godlike) figure that can be said to be connected to Satan in their mannerism and purpose. In jewish religion he is also known bad but he is one of God's angels. Satan serves as the main antagonist for the jews & christians.

To some Satan is "almost" all-powerful while others limit his power to only corrupting or deceving mankind - some religions do not regard Satan as pure evil and instead believe he is granted the ability to corrupt humanity in order to test faith - though in the popular mind Satan will always embodies the raw and evil demonic possession.
