How do you go and decide to battle against the god of systems since you are clearly weaker then him???
Another thing since he did all that because of his previous hosts that will mean he has emotions
How did he not feel a thing when all his powers are taken and he fell from grace?
Thirteen's transition from a powerful system to a vulnerable mortal is a significant change, yet his emotional response to this drastic change is like nothing happened
Or should I say not explored?
