Blue Submarine No. 6

In the near future, the Earth's oceans have risen and flooded most of the sea-lying land on Earth. The rogue scientist Zorndyke caused the flooding, which killed billions, and most of humanity's remaining cities have been attacked or destroyed by Zorndyke's army of "hybrids". Humanity's best hope for a resolution to the conflict lies with its submarine forces, among which is the focus of the story, Blue Submarine #6. (Wikipedia)
