Character derailment


 * NOTE: Please do not say this is Flanderization. Not all types of Flanderization involve character derailment, just like how not all types of character derailment is Flanderization. It can be in the entire series.

Character Derailment is the opposite of character development. Instead of learning from mistakes, they just get worse.

It is not to be confused with Flanderization, as it involves over-exaggerating and amplifying a character's trait(s). Character Derailment, on the other hand, refers to a character's trait(s) becoming vastly different compared to what was previously shown.
