Levitz, LaRocque and Mahlstedt have the Legion protect RJ Brande in Legion of Super-Heroes 17 (Dec 85).
Leland McCauley is the villain in this story, still consumed with envy over Brande, and wanting to kill him, for no better reason that Brande is wealthier than he is. But Brande is protected by the Legion, and McCauley recalls how the team was first formed, when Lightning Lad, Saturn Girl and Cosmic Boy stopped an assassination attempt on him.
Dream Girl gets a vision of Brande dying, and it being the Legion's fault. To me, at least, this harkens back to the way Dream Girl was most often used in the 70s, suddenly announcing a foreseen event, which the Legion would then try to stop.
Brainiac 5 is too busy to help, working on figuring out Invisible Kid's unstable new powers. Sensor Girl is able to tell which elements in the Kid's blood are the ones affected, and Brainiac 5 wonders how she was able to tell this.
Sun Boy, Star Boy, Lightning Lass and Timber Wolf head with Dream Girl to RJ Brande's asteroid home. His robot butler charges himself up with Sun Boy's powers, and then tries to kill Brande, though the Legionnaires stop this.
They are easily able to trace things back to McCauley, who doesn't even bother trying to deny it. Buut Brande does not want to press charges, so nothing happens to the guy. But as the story ends, Brande decides to leave his life and identity, and go off secretly. Effectively, he does "die," with the Legion's help.
The last few pages of the issue consist of pictures of the Legionnaires, along with their identities, homeworlds, and powers.
There is no order at all to these listings, although four of the five new members do appear on the final page.
