You are the owner of all symbiotes!

Agony, Toxin, Carnage, Venom, Knull - the god of symbiotes, creator of the first necrosword. You possess them all, they can create tentacles from your back and extend (grab objects and move them)/stick their heads out of their owners' backs, speak to them telepathically, they can form a shell around you (they become you, but they are already visible), and yes, they need to eat brains, or chocolate, to survive here. That's why you often stock up on chocolate, and rarely let them eat brains. They love to hurt others, always convincing you to eat the brains of others. (If you die, they will too.)
You have abilities - (not from symbiotes) telekenesis, you can catch bullets/knives if they fly at you, you will easily hit or dodge.
Now
You're at home, they're not looking for you because you're safe, and the symbiotes (inside you) are asking you to eat your brains, you don't allow them, now they know absolutely everything about you, and you know them well, almost everything.
