Doom Patrol Vol.2 #17
As Invasion! strikes, the Alien Alliance attempts to get a foothold near the Arctic Circle by sending the Gil'Dishpan and their mercenaries as an occupying force. The Chief concludes that this is where the Doom Patrol is most needed, and the team suits up for underwater combat. Having been slighted by the alliance in his attempt to gain membership, their old enemy Garguax joins forces with the Patrol... adding his team of Sirens to their forces. The battle is already underway when they arrive, and Aquaman is leading the Atlantean army against the invaders. Dane Dorrance and his Sea Devils are also present to contribute in the war efforts.
