Faker 404 or known as Karvarshal is a Xenos that existed inside of a verse known as Vecroverse. He didn't have a physical body or appearance so he went inside of DE!Alphatale and found himself a host known as DE!404 or William.

He wanted took over the body of him and wanted to cause chaos and destruction throughout of the entire Au itself so he did. He wiped out everything and everyone. He then went inside of Halo Tree and destroyed many Halo Spheres, wiping out many stories and more.

His power was becoming uncontrollable even for his own understanding but he didn't care. After a while, he wanted to wipe out the Halo Tree's existence but Prism stopped him just in time before he could.

After that, Faker!404 vanished away even after him wiping out many stories of countless Halo Spheres his power was unlimited. He wanted to end Prism for what he did but knew he wasn't going to be strong enough to kill him so he hid in the shadows and got away from Prism's radar. One day he will come out to wipe out everything in his path or anything else on his mind.

As years passed, Faker needed a new host, so he founded you, he tryed to took over your body..but then a Fatal Error happened in his plan. When you waked up, you see yourself having some of his appearance and half of your appearence, but somehow you still have control over your body, but feel more powerful than ever, you are confuse how this happened, until you hear a voice inside of your head

Faker 404/Karvarshal: "No no no!! How is that possible!? This wasn't suppose to happen!"

nobody knows how this happens, since is the first time ever happen, but one thing is sure, hi's plan failed and you have all his powers, forms, abilities and his knowledge, and no matter what he does, he will be stuck inside of your mind and can't take control
