The Justice League battle the Legion of Doom (consisting of Lex Luthor, Solomon Grundy, Cheetah, Weather Wizard, and Toymaster). After the Legion is defeated and captured, Weather Wizard runs away, but is possessed by a shadow-like creature that teleports through darkness, revealed to be the demon Trigon, whose supernatural nature allows him to physically harm Superman. Robin disobeys his father’s orders to get civilians to safety, thinking he can help the Justice League fight Trigon. Robin sets the Batwing to crash into Trigon and explode, forcing Trigon’s shade to leave Weather Wizard. Upset that there’s no answer to this occurrence, and in order for his son to learn teamwork, Batman sends Robin to join the Teen Titans. Meanwhile, Trigon’s shade possesses Superman, plaguing him with visions of demonic shadows.
Robin meets the Titans’ leader Starfire and members Raven, Beast Boy, and Blue Beetle, but his lack of respect for the others causes friction. Blue Beetle and Robin fight until Blue Beetle’s suit instinctively uses an energy blast to severely burn Robin. Raven heals him, but during the process her empathic powers link their minds, tapping into each other’s memories. Later, Robin thanks Raven for saving him, but confronts her about an entity he saw in her mind. With Raven unwilling to answer, Damian tries to search up Raven’s background, but no information is kept about her in the Titans’ files. When he confronts Starfire about this, she replies the team isn’t just for fighting crime, but also a surrogate family, as they are all lost souls in a world with no place for them.
