(Final Night #1) - Superman organized a summit of superheroes, including Gates, to listen to an alien named Dusk. She'd seen the Sun-Eater snuff out the sun of countless planets, and she was there to warn the heroes that the Sun-Eater was headed towards Earth. The heroes discussed different ways to deal with the menace. Parallax saved the day, sacrificing his life to dispel the Sun-Eater and reignite the sun.

 (Impulse #21) - The timelost Gates and the LSH asked Impulse if he could help them return to the 30th Century. They went to the Flash Museum to use the Cosmic Treadmill, but Impulse didn't know how to properly utilize it and just sent himself and various Legionnaires forwards and backward in time 10 minutes. He then accidentally brought back raptors from the Jurassic era. He managed to send them back to the past, but the LSH said they definitely didn't need his help.
