Hero's Redemption is an event where a villain changes his or her mind and becomes one of the good guys. There are several reasons for an anti-villain, anti hero or bench person to redeem himself/herself
- To confess their love for the hero
- Having had enough of the villain's abuse/evil ways
- Some end up killing the villain in question
- A selfish Jerk realizing the error of his/her ways
- Betrayed by the villain
- KillJoy : she overhears Bing Bong plotting to make Riley's mind go down so KillJoy can control Riley's mind for evil after KillJoy befriends Party Pooper.
