Intro v3:

Long ago, two races ruled over Earth: HUMANS and MONSTERS.

One day, war broke out between the two races.

After a long battle, the humans were victorious.

They sealed the monsters underground with a magic spell.

Many years later...

Mt. Ebott

202X

The legends say those who climb the mountain never returns.

...

But one day.

A human named FRISK fell to the Underground.

They travelled the underground

Making different types of friends

And foes.

But at the end Frisk made their way to the end.

Freeing the monsters from the underground.

But after that...

They felt empty.

Thanks to the emptiness they felt.

They were searching a way to fulfil their emptiness...

They almost killed all the monsters in the underground.

Monsters that considered Frisk their friend.

Flowey saw that as an opportunity to execute his plan.

He thought that with the help of "their old friend" he could accomplish that.

- Flowey: -

You won't give me any worthless pity.

Creatures like us...

Wouldn't hesitate to KILL each other if we got to each other's way.

So that's...

So... That's... Why...

But Flowey then realised that "their old friend" would not care about them.

They will try to kill them for more power.

...

And in the end the human killed him.

...

Many genocides routes have been executed.

Flowey is tired of the countless times the human has killed him and all the other monsters.

He changed his mind and made a new plan.

He will not make the same errors again...

But before he will take a last breath before starting his plan.
