Dark Gods (Marvel Comics)
The first Dark God, Perrikus, appears when accidentally freed from a prison in Asgard by the Thunder God Thor. Not knowing what has occurred, Thor departs and Perrikus brings his brethren to Asgard. The core group are Perrikus (god of "Power Unlimited and Energy Infinite"); Majeston Zelia (the leader and Perrikus' mother); Adva (god of Portals and Knowledge); D'Chel (god of Illusion); Tokkots (god of Rhyme) and Slototh (god of Filth). With an army they invade and overrun Asgard, capturing Odin, Thor's father and the ruler of the Norse gods.
