#invalidcode!sans

He's a sans who can't enter his own au because his Code was invalid to his au after he go out of his au, and somewhat his Code was changed. After that, he meet core frisk who take him to the omega timeline. But he doesn't like how his Code was corrupted since he can't enter his au, so he get out and find Total Null. He get interested so he copy total Code and paste it on him, and it's actually work. He happily take Total's similar form and modify the Code because he can manipulate the Code due to his corrupted one, but his invalid Code still there and ruin his modifications. He get irritated and decide to trying and trying to get rid of the invalid code :D

He has power to manipulate codes, copy and paste the codes, and even destroy it. He can also corrupted anyone codes whenever he like it. He like to joking too when he fight :P
