This is how the Human Mane 6's new allies and ending goes in Ernie the Dragon Hunter.
[after that, everything was being repaired]
Brian: I'm glad that's over.
Human Twilight: Hey, thanks for saving me.
Brian: Of course, I didn't wanna see a girl shot.
Human Rainbow: Yeah. Um, we're sorry for almost attacking you guys, Ernie's not really much of a great guy as we thought.
Princess Celestia: All is forgiven, and I'm going to arrange for a new home to be made for you.
[Shows them their house]
Human Rainbow: Oh, yeah!
Human Rarity: I love it!
Human Applejack: Thank ya, kindly.
Human Pinkie: [excitedly] Do we get dragons too?!
Yuna: I'm afraid you're gonna have to wait for a while for that, to happen.
Nightstar: [growls in agreement]
Human Rairty: That's okay, I'm not ready for any dragons right now.
Human Fluttershy: By the way, these foals are too cute. Is it okay if we privilege to be foal sitters with them?
Princess Luna: Sounds fair enough to me. Elsa and the others are sometimes too busy to watch them.
Twilight: You are welcome to watch them while we're gone.
Human Twilight: Thanks equine me.
Yuna: [messaging] Today, me and my freinds have had one of our biggest challenges yet. Against Ernie, a Sith Lord and an enemy of Brian Griffin. We may of lost a few good members, but we also gained new ones, and we have DRAGONS!!!
