I think the Competitor or the Partner as the Light called him is Sinestro....based on the fact that The Guardians of the Universe were not aware of what the six league members did 5 years ago and that the bomb planted by the Partner was of unknown alien design... the team dealt with Apokoliptian tech in the past so Nightwing would had know if it was Apokoliptian.
