Tales of the Teen Titans 58 (Oct 85) is the last issue of the run to feature a new story, by Wolfman, Patton and Tanghal.
Neutron is back in action, now a member of the Fearsome Five, alongside Psimon, Mammoth, Shimmer, Gizmo and Jinx.
They spend the issue fighting against Nightwing, Wonder Girl, Changeling, Starfire and Jericho. It's a visually dynamic fight, although it also comes off a bit like filler.
In the middle of the fracas Psimon gets teleported away by the Monitor. Despite the fact that Lyla is now Harbinger, an event which occurred in the first issue of Crisis on Infinite Earths, the Monitor tells Psimon that it is still three months until the Crisis begins. That was likely due to the fact that these stories were meant to take place a year before the current tales in the Baxter run, and Crisis was already about halfway through its run.
Jenet Klybirn gets Cyborg back to STAR Labs, and saves his life, although he winds up looking as he did before, with all the metal parts. He is sad that no one got to see his new body. The rest of the story is more fighting, with the Titans taking down the Fearsome Five, who have no strategy now that Psimon has been taken from them.
It's not a great ending to the run, nor a great lead in to the Baxter series, which chronologically follows this story.
