I have many ideas. the first things I had in mind, look a lot like the things we already have, so I'm trying to come up with something new. I'm just brainstorming with the ideas below. But I might go for the Reaching one or the conscious one. 

The Reaching One/ Heavenly one
wants to get as high as possible. He wants to take control of the sky and if eventually possible, whatever is beond. And to fill the sky with creatures of his own design in a utopia that's safe from the dangers on the ground. Creating an airborne ecosystem for his creatures in a way that no organism has ever to come down to earth again. - think flying creatures and immensely tall trees

The Flaming one
wants to bring fire to this world through his creatures. tries to create creatures that can produce fire. -Think dragons for instance, but perhaps not as overall powerfull as that. 

The illuminating one
wants to create light al over the planet, night and day. - Think glowing plants

The Dark one
Wants to control all species. - think mind controlling virusses or a plague that affects al living things. 

The devouring one
wants to eat the planet. - think creatures that eat about anything, only to reproduce themselves at massive rates. Like a plague. 

The Conscious one
wants to create a hive mind for the planet, made up of all organisms. - think Pandora, the planet from avatar (not the airbender, but the blue guys)

The growing one
wants to create organisms as large as possible. 

The lonely one
wants to make friends with another entity trough their limited communication

The procreating one
wants to create a species or group of species, that is capable of the same things as he is. 

The Communicating one
wants to create a way for the entities to communicate fast and easily.

The Frankenstein Fuser
Wants to take the deadliest creations in the world and put them together to make a fearsome -grown together- symbiotic species. 

The wireless one
wants to create internet

Cthulu
wants to create a race that can summon him to this world.
