If you get most of resources (energy, army, etc.) you would become the one with ultimate power, the strongest creature. Ruler of the world.

There are 2 types of creatures with ultimate power.

Dark creatures

They can be objectively the strongest creatures in the world. Having the biggest amounts of energy, strongest army, most of resources.

Light creatures

But light creatures always win at the end. Even if they're not strong in a common sense, and never wanted the power in the first place. They posses abilities of a higher level, which dark creatures tent to ignore, because they consider them as weaknesses.
