Disclaimer: the pheonix (5) is only all of them since it is the easiest to change with familiars and I ran out of ideas
1) top right, griffin with the powers to manipulate the sun with slight fire
2) bottom left, coatl with water manipulation (including ice)
3) bottom middle, wyvern with fire and slight sun manipulation
4) Bottom right, bicorn with earth and rock powers
5) centre, pheonix with only a tad of everything, main power based of familiars (won through comps)
