One of the mecha rocs manages to peck eye out of the god, causing the god take step backwards.
From south appears a man made of flames, bringing fire in its footsteps and setting the forest ablaze. You can sense that is has power to capture one's mind and steal pieces of it. In addition it has connection to the demon that slithers out from the forest, being in superior position in their relationship.
And the demon... imagine
this, extend its shoulder more on sides and imagine it having scaled up head of
this, dragonfly's wings and a snake for tail. It is wearing black and silver leather cuirass and carrying a halberd with extended blades. From its aura you can tell it has a plethora powers. For example it has 6 different powers that affects one's mind in different ways, one affecting its own mind, superior muscles and night invulnerable skin. And a power that's related to plants...
A flying demon above shoots a ray of some sort at the god. All physical properties of the god disappear, as if it isn't there. Also a horde of lesser demons is coming out of the forest.
Chaos Lord slithers into front of the god, uncomfortably near you.
"Haha! You lost! You can no longer do anything!"The god turns its only good eye at the demon.
"Maybe. Maybe not." he says, summoning a glowing symbol into air. Chaos Lord cowers away from the symbol, hisses and slithers away fast.
"Slaughter everything!" its voice echoes from the forest.
