Papyrus: But I could've tried to-
Gaster: you're right, Papyrus. You aren't the strongest fighter. But strength isn't just power and aggression. You excel at something none of us ever had. It's something that gives you greater strength than anything else.
(Gaster taps Papyrus' head.)
You have the strength to get through anyone's skull, no matter how thick it is. You have the strength to help your friends when their in a dark place. I know that for a fact. I had reached the darkest depths. So far down, I could have forgotten I had ever seen the sun. But even in that hopeless place, you were the light that helped me find the surface again. I have never been a great father. But if anything remains that lets me speak to you as one... I want to say this as a father to his son. Your hands are not meant to tear things apart, but to make bonds stronger. You aren't a fighter. And that's something I'm very, very proud of. Don't ever change who you are.
(Papyrus cries and hugs Gaster.)

**"Wing Din Gaster"** also known as **"Gaster"** as a former villain turned hero in the YouTube webseries "Glitchtale." In the first season of Glitchtale, Gaster starts off as a tragic villain that was trapped in the void and was interested on the soul of Frisk. Due to Gaster's interest on Frisk, he attempts to kill Frisk, but is killed by Sans. In the next reset, Gaster is brought back to the timeline by a machine that Sans had fixed. Gaster reunites with Sans and apologizes to Frisk for his aggressive behavior thereby redeeming himself for his past villainous actions. Gaster later becomes the tritagonist on the second season of Glitchtale and plays an active role in killing Bête Noire.
