my old huge undertale and danny phantom fixation is thriving of off this
Imagine Danny being conflicted because the monsters really want out, but he knows how cruel his government is, so he doesn’t think it’s a good idea. Not only that, but as a halfa, he can’t give up his soul to help them. They need a human soul, and his is forever altered into something only half human. So he tries something else!
He phases through the mountain to search outside several times, circling around the mountain. Luckily, it’s very secluded due to old tales and stories scaring people off, even now! He starts trying to use his powers to smash an opening in the cave walls, or find some natural tunnels that could be close to the cavern and break the wall between the cavern and the tunnel for an easier ticket to the surface.
Wondering to himself “Why didn’t anyone try this??” the whole time. Let’s say there was some stone or something that negates magic in the tunnels, but since Danny doesn’t have any, he can get rid of them easy-peasy.
After that, he goes to Asgore and goes “Hey, guess what? I made a tunnel for you guys to get out and got rid of those weird stones that negate magic! But please don’t go too far because we don’t want anyone to get caught, just take my advice and stay near the mountain base for now. Now that I’ve said that, I’m exhausted, so goodnight.” and just passes out or something, because you can’t tell me the whole thing wasn’t a long process that took it out of him.
I like to think that while he was asleep, they waited on him because they were so grateful he found a way for them to finally see the surface! Besides, they waited centuries for it, what’s one more day? It’s likely that not everyone is as willing to do this as the rest, but they do it anyways. He’s very touched when he wakes up and they’re all still there, and once everyone’s ready, they all go outside. Coincidentally, it’s sunset when they get outside.
They might set up camp or something, and once that’s all said and done, Danny finally gets to show them the stars.
Or if that doesn’t work, he goes to Clockwork to ask him if he thinks something can be done. It gets a little complicated concerning the timelines, but the end answer is yes and they get to brainstorming.
Another idea is that maybe, just maybe, Danny could find a way to at least get them out of the mountain for a little bit by bringing them to the ghost zone. They still want to see the surface of their world, though, so it’s just a temporary solution. I definitely think he’d talk to Asgore about this feeling nervous because it’s not what they want, but probably something they need. And still, it’s not a permanent solution. It’s more of a field trip or something.
He expected Asgore to be disappointed with this idea, but he couldn’t be more happy and willing to accept this idea. It’s a bit of a process because they need to figure out the details, including finding a good spot for them to go first.
So yeah! Field trip for the whole Underground, I guess!
