It's just fatal glitching out and code and core watching and something else. I wonder what it is?
Anyways, let's talk about fatal power
First one bypass
Bypass is a broken fusion of the fight and mercy button. Bypass, let's you. Bypass the enemy defense attacks are escape when the mercy button is broken bypass can't work on someone Stronger than the user. It can be used to hack a person as long as the user wants, and it can be used to bypass getting attacked or killed
Next, the glitch knife
After getting hit with the power that the monster found to defeat frisk the knife got a glitch, letting the user hit someone even if they dodged it. It could attack the person code, and it does infinite damage to anyone hit with it
And for the other powers, they are the same as fatal error sans
Immortal
Copying
And seeing code
That's all of fatal powers

And fatal error frisk lore
Fatel is from a dead au in the au. The monster found a way to stop frisk from coming back and resting, so using the power they found on frisk end up not working and kills everyone but frisk turning them into fatel error frisk they end up staying in the dead au till core found them and become their only friend core ask them to come to the omega timeline but fatel refused to leave the void so core would hangout with then from time to time having fun
