Blue Devil helped Flash fight the Injustice League's plants at a nuclear power plant. He shot at the plant with his trident, destroying one tentacle. Another vine took out one of the factory's chimneys. Captain Atom absorbed the wave of nuclear energy before it could spread.
When magnetic field disruptors planted by the Reach threatened the Earth, Blue Devil joined 39 other heroes of Earth in a briefing in Metropolis. The heroes would use a computer virus provided by Lex Luthor to safely disable the disruptors. The heroes were paired off with another into twenty squads: one member would run interference against weapons guarding the disruptors, allowing the other to get close enough to plant the virus.Blue Devil was assigned to Mu Squad, and worked alongside Doctor Fate.
Within thirty minutes, all squads had succeeded in their mission.
In the comics, Blue Devil is Daniel Cassidy, a stuntman accidentally bonded with a high tech "Blue Devil" movie costume and later with an actual demon. He is a member of the Shadowpact, a team of mystical heroes solving supernatural crimes.
This is Blue Devil's second animated appearance. He first appeared in Justice League Unlimited as a background member of the expanded League.
