Justice League of America, Vol. 1

The League trace the last of the Luciferase to the Pacific Ocean, and the island of Lord Claw, ruler of the cult of Fiatlux.

In hell, Zatanna manages to open a gateway to Earth, though Hawkgirl is suspicious of how easily she manages it.

Travelling to Lord Claw's island, the League are attacked both by the mutated animals he keeps and the dragons he has created. Infuriated by their success, Claw causes the island's volcano to erupt. On the beach, Zatanna and the others appear and in a display of power which her team-mates have never seen from her, she manages to snuff out the volcano.

Hellrazer, having possessed Zatanna, now manifests himself and defeats Lord Claw, growing to vast proportions. Zatanna, though, remembers the spells he cast while using her body and opens a portal to hell into which other demons drag Hellrazer, cursing Zatanna as he goes.
