Justice League vs. Teen Titans

Trigon, a demon, conceives Raven with Arella. When Arella discovers his demonic nature, she flees to the mystical world of Azarath. Trigon finds Raven and slaughters Arella and the people of Azarath. Raven barely manages to seal Trigon inside a magical crystal in what remains of Azarath.

Sometime after sealing Trigon, Raven joins the Teen Titans and begins a wary, guarded path with the group. She carries the weight of her lineage as she learns to control her powers. Her place within the team would come to shape her future.

Trigon sends a demonic corrupter to Earth, signaling a larger invasion. The entity briefly possesses Weather Wizard after a clash between the Justice League and the Legion of Doom. Damian Wayne helps defeat the corrupter, but leaves with little background on its origins.

Nightwing brings Damian Wayne to join the Titans, where a different rhythm and chemistry challenge him. Damian clashes with the team, convinced he should lead decisively. Raven heals a heated moment with Jaime, forging an unexpected bond as Trigon's presence begins to awaken within Raven.

Batman and Cyborg investigate the earlier attack that sparked the crisis. Superman is briefly possessed by one of the entities and lashes out at Atomic Skull, drawing attention from Diana and Batman. Batman calms the threat with kryptonite, but the possessed Superman escapes before kryptonite can fully disable him.

Starfire leads the Titans on a carnival trip to help them grow closer, hoping to ease the rift between the new teammates. Unbeknownst to them, Raven is summoned by Trigon’s entities, who attack her and force the Titans to intervene. After the assault, Raven shares her backstory with the group, explaining the toll her lineage has taken.

Back at the Titans' tower, the Justice League moves to take Raven away to avert disaster, and the heroes—Flash, Diana, and Cyborg—are briefly possessed. Batman resists the possession and fights to protect Raven as the League beats the Titans senseless. Raven agrees to go with the League to avert catastrophe—only for Jaime to strike Cyborg down and free him from possession.

Raven travels with the League toward Superman and summons Trigon to Earth. Cyborg wakes and uses Apokoliptian tech to teleport the group to confront the demon in a perilous showdown. Damian stabs Superman with Kryptonite, freeing him from possession, and the now-clear-headed Kryptonian heads to stop the entity from ensnaring Flash and Diana.

The League remains on Earth to battle Trigon while Cyborg and the Titans dive into a journey to Hell to rescue Raven. Robin faces a demon that mirrors his deceased grandfather Ra’s al Ghul, in a tense confrontation, and ultimately overcomes the threat. The perilous rescue tests the team’s resolve and unity.

Raven crafts a spell to re-imprison her father and places it on her forehead, hoping to keep Trigon contained. The ritual represents a decisive shield against invasion and marks a personal turning point for Raven. The spell buys time as the teams regroup from the battle.

Robin convinces a hesitant Raven to stay on Earth with the Titans, choosing to remain with them rather than rejoin the League. The Titans solidify their bond as a newly reinforced team faces looming dangers. Raven finds belonging with friends who accept her powers and past.

In a mid-credits moment, a mysterious costumed girl rides a flying chunk of rock toward the Titans Tower, hinting at new and looming challenges for the team. The teaser suggests Raven and the Titans will face further trials beyond the immediate crisis. The scene leaves the door open for future adventures.
