Theoretically Speaking...

When it pertains to the creatures of the Void they often are adaptive, vicious animals who seem to have lived in constant threat to their well being. That their habitat itself has many many predators and they all want to eat one another.

And right now we have: Cho'Gath Vel'Koz Kha'Zix Kog'Maw Rek'Sai

If you set them up as a team however, such as one that normally operates like what we see in Summoners Rift there is no dedicated Support. Cho'Gath or Vel'Koz could be taken support but they tend to be favored(And built for) other positions.

Theoretically if there was a support character from the Void what would it be like? I was thinking some sort of symbiotic creature, something that learned to care for/protect the nastier monsters in order to keep itself safe...?
