The serpent Apophis is the enemy of Re. In one of the texts Seth is the agent of victory. Refresh your memory. Marduk is the agent of the gods in the conquest of the dragon Tiamat in the Akkadian myth.
In another text the gods whom Re has given birth employ their magical powers to destroy Apophis. We have an interesting parallel here with the victory of Marduk over dragon Tiamat at the Babylonian New Year Festival.
