Chernabog

chernabog is the mian antagonist of Ghost ghouls spirits oh my.

acorrding to ledgend. he was once a king so evil that his spirit lives on as a demon. now he is the black god of death and chaos.

chernabog is only allowed to awaken once a year (useully all hallows eve) but is only alowed to walk the earth after 100 year for 1000 years. his very presence brings ghost gouls and demons into the world. at one point he attempts to possese dr doofinsmirtz but was exorsised by vanessa. his spirit rest safely in the mountins. Vanessa ,Jermy, stacy ,candace and Johnny attempt to exorsise him from the mountins but were forbiddin to do so by albert

at the climax of the film his minions were defeated by the group who make thier way to the mountins, were they battle him in his true form. they find him unbustable (makeing phineas and ferb look easy). chernabog nearly deystroys them but thankt to vanessa's ecto bomb they blast him back into the mountins. since he was a god he was likely not killed, and the ledgend says he will be free after a hundred years sugesting he might return .........
