Sometimes when Peter rested or was exhausted it hijacked his body. Taking control completely for hours at a time just to have it's definition of fun..it wasn't just the power he hated, it took the worst of his personality with it. Acting nothing like Peter. He could be cold, mature, flirtatious and destructive.
Peter was completely unaware of the fact it ever happend.
Causing destruction just for the thrill of it all.
Staring at a blaze he started completely focused on it.
*He's drinking, having 'persuading' others to serve him.
Talking like this towards your *Avenger or ......* parent.
