Ramattra needs a mythic skin so why not make him Apep the Egyptian embodiment of chaos? His Mythic would be based around the Chaos Serpent, giving him a dark, ancient-god aesthetic with serpent-inspired armor, Egyptian details, and cosmic destruction effects.
It fits him really well since his whole character is about rebellion, destruction, and fighting against the existing order.
For his Omnic Form, I’d keep him pretty sleek but give him black and gold armor with some serpent-inspired details. His eyes and the energy running through his body could glow purple, with Egyptian symbols engraved into the armor. His staff could also be redesigned into a serpent-themed weapon.
Then, in his Nemesis Form, I’d make him look much more intimidating and monstrous. His armor could take on a cobra-like shape, with larger shoulders, scale-like details, and more visible purple energy. A giant spectral serpent could also appear behind him when he attacks.
For Annihilation, I’d make the whole effect feel like Apep has been unleashed. A huge dark eclipse could appear behind Ramattra, with a massive spectral serpent surrounding him and Egyptian symbols appearing on the ground.
If anyone wants to design the skin and collab lmk, it would be such an amazing mythic due to Ramattra not having a limited selection of skins!
