Kami laughed, as Mithias launched the blade, his electric body disappearing in a flash of light before the blade could contact him. While in his electric form, Kami could move at nearly the speed of light, slowed down only slightly by electromagnetic friction. It was nearly impossible to hit him, even if you found an attack that could hurt him, as he nimbly danced around each slash. He then appeared in front of Mithias, a smug smile on his face. "Only fools challenge God. Did you truly think you could take me down?" He seems to punch you in the face, and yet, even as he does so, his hand passes through your skull. Lightning crackles over your skin, as every one of your muscles is electrically activated, holding you in your position like an insanely bad cramp. And even as you look at him, you can feel Kami reaching into your mind, taking a hold of those things that would make you rebel, make you yourself. Love, lust, hate, anger, passion. He takes a hold of them, and begins to rip them out, rewriting the base signatures of your brain. Quite soon, if the process wasn't interrupted, Mithias would be reduced to one of Kami's zealous followers.

Even as the group of humanoids attempts to cage the creature once more, it holds it's many hands against the edges of it's prison. Even as the threads of magic are woven, it seems to dispell them, ripping through the magic with it's own power. While the humanoids seem to be weaving their power, this creature simply controls, simply will. It wasn't casting a spell in any traditional sense, or even the use of magic, rather some form of innate control over reality, A battle between titans, as massive amounts of power are thrown about on both sides, and yet the mysterious creature uses some form of magic as well, as a beam of blue energy shoots out from it's mouth, ripping through the vacuum of space.

Together, all six of the humanods erect a shield, which, by pure luck, or perhaps fate, protects Kaika as well. The beam strike the shield, and, denied it's original target, it flows over the entirety of the planet, seemingly passing through all matter harmlessly. A moment of silence passes after the beam's wake, as if everyone were holding their breath. Then, with a sound not unlike that of a boot stepping on gravel, the world falls apart. Not destruction, not an explosion, but rather the systematic disintegration of every molecule affected by the mysterious energy. To the naked eye, 90% of the planet simply disappeared magically, leaving Kaika and the humanoids standing on a small floating rock that had been shielded.
