They came here once before, long ago.

A great armada appeared in the sky,

laying waste to all who opposed it.

The leader of the invaders was a being called Darkseid.

A name cursed and feared in every universe.

Darkseid was met in battle by Earth's defenders.

The old gods, men...

Atlanteans before their descent into the sea...

Amazons before their betrayal and enslavement

and guardians from the stars.

Their histories had taught them

not to trust each other,

not to hope for an alliance.

To fight apart.

[door hisses]

[Darkseid breathing heavily]

[yells]

[Diana] As Darkseid waged war on Earth,

he found a secret there.

A power hidden in the infinity of space.

He called forth mystics

who worshipped and controlled three objects...

the Mother Boxes.

Wait, wait, wait.

"Mother Boxes"?

Indestructible living machines,

made from a science so advanced,

it looks like sorcery.

To conquer, three boxes have to synchronize

and join together into The Unity.

The Unity cleanses a planet with fire,

transforming it into a copy of the enemy's world.

All who live become servants of Darkseid.

Alive but drained of life.

Parademons.

[horse whinnying]

-Amazons! -[Amazons shouting]

[Atlanteans yelling]

With me!

[all yelling]

[Zeus growling]

[parademons screeching]

[Amazons yelling]

[Diana] But before The Unity could synchronize,

the defenders of Earth attacked

and fought as one.

Amazons alongside Atlanteans.

Zeus and his son Ares

alongside the guardians from the sky.

A golden Age of Heroes fighting together

to defend life on Earth.

[men yelling]

[man groaning]

[Darkseid grunting]

[Darkseid grunting]

[groans]

[Atlantean king yells]

[growls]

[yells]

[Darkseid grunts]

[straining]

[both growling]

[yells]

[Darkseid groaning]
