Ok....so....uh....let's see, all of see Nightwing like this, right?
Evil, ugly, just...a Destroyer. But what if he ISN'T a Destroyer? Ok...you probably thinking: STORMSUN WHAT IS WRONG WITH YOU????????????
Well, I think Nightwing is different. In How The Grinch Stole Christmas, (SPOILER) the Grinch wanted to take away Christmas because it made him feel sad, lonely, depressed, and angry. Nightwing is sorta like the Grinch...except in Anok there was no such thing as Christmas. But we know that Hollyblaze died (if you read the Short Story in the back of Stormbound). So it makes him sad. AND we know that Jungle Herd treated him nice ONLY because he would get the healing starfire. They wanted him to use the starfire for THEM. Such selfish brats. They didn't think that maybe Nightwing (at the time he was just Nightflame) wanted to be a normal pegasus. Or that he didn't want to use his starfire for them. And when he got the starfire he left his Herd, and Anok. He came back and was Nightwing the Destroyer. But only because he was angry, he felt lost. Like he wasn't....real. Like he was just so different, that no one would understand him, or treat him normal. So Nightwing decided: MAN I HATE THESE PEGASI SO MUCH I'MA START KILLING THEM IF THEY DISOBEY ME. His mind stopped working. And I'm sure he wanted to stop. I'm sure he wanted to just stop it all, and tell Anok that he was a normal peggy, who happened to have the starfire. That he was just...him. But he couldn't. Ever. All his life, 4 HUNDRED YEARS, he was the Destroyer, the Cruel, the Mean, the Brat, the Angry. The Sad. He couldn't turn away from it. Idk if any of this makes sense, but it just makes me so sad that Nightwing...well....I don't know. I just feel so bad for him. The dude really messed up. But he messed up so bad, that he couldn't fix it.
