The Green Chaos Serpent is an enemy from Hexen, and also D'Sparil's steed in Heretic. They appear as tall serpentine humanoids with large horned heads. They belch out highly damaging fireballs. In Hexen they can also bite the player in melee, however this can be easilly avoided because it takes them a long time to perform. D'sparils steed in Heretic will begin to belch out addtional fireballs once it has taken a certain ammount of damage.
Green Chaos Serpents in Hexen have 250 Hit Points, while the one D'Sparil rides in Heretic is much stronger at around 2000 Hit Points. They first appear in Hexen in the first hub.
