Wrath of the Pony Gods

As the group waited in their normal training spot, Rainbow Dash groaned and said, "What is taking Blast and Flutters so long? We've been here for hours and they're still not here!" She was getting frustrated with her son, who she was starting to realize would be a hoofful.

Meanwhile, Rainbow Blast was at Fluttershy's house trying to explain why he needed Discord's help with today's training session without telling her the full details. Fluttershy said sternly, "I'm not letting Discord help until you tell me exactly why you need his help."

Rainbow Blast sighed and said, "Fine, sometimes you're more stubborn than my mother. I need Discord to turn all of us into Earth Ponies. I need to teach everypony how to fly by manipulating their Ki. I've learned how to fly even if my wings are broken, but the rest of you don't know how to fly without wings or magic. It's important that you learn not to rely on your wings and magic, and more on your Ki. Black is relentless, she won't think twice about ripping your wings clean off, and then how are you going to fight her without being able to get up close?"

Fluttershy got scared at Blast's description of Black's cruelty, but calmed herself down saying, "That's all you needed to tell me. Discord, come here for a second!"

She called out to the God of Chaos, who walked out of his room yawning, "What is it Flutters? I was just enjoying a nice nap-" his eyes bulged out when he saw Rainbow Blast and asked "Who is that and why does he look so similar to Rainbow Dash?"

Blast shoved his hoof in Fluttershy's mouth as she opened it, saying, "I'll explain everything when the time is right, I need your help."

After explaining what he needed Discord to to, Discord teleported them to the field and stroked his beard saying to the group, "I don't quite understand your new friend's way of thinking, but I'm too tired to ask questions right now." He snapped his griffin claws and in a second, the wings and horns of anypony who had them disappeared. Discord looked at Rainbow Blast and said, "I'll be back at Fluttershy's house when you're ready to turn them back to normal. Ta!" and with that he was gone

Rainbow Dash yelled at her son in an oddly loud voice, "WHAT THE HECK WERE YOU THINKING!?"

Rainbow Blast grabbed his ears in pain from his mother's yelling and said, "You can still fly if you focus hard enough. You don't need wings to fly. I've had my wings broken by Black more times than I can count, and I've still flown perfectly without them." He proved what he was saying by flying into the air and laying down on a cloud. "If you want to continue your training, you'll have to find a way to get up here. And don't bother trying to shoot me down with Ki blasts." he waved his hooves in a circle and a force field of Ki surrounded him and the cloud he was on. "Now, I'm going to nap while you try to figure out how to get up here." He said before falling asleep.

Everypony stood there in shock at what had just happened, except Fluttershy, although when everypony else glared at her, she recoiled into a ball. Twilight calmed the others down and said, "No, we shouldn't get mad at Fluttershy. Although she did agree to help Blast with this, Blast is the one who planned all this. Blast is right, all of us except Sunset saw what Blast looked like when he arrived here. If Black's the one who did that to him, we're going to need to learn to fly without wings or magic. Now let's get started!"

After about two hours of trying to get it right, the group still couldn't get their hooves off the ground for more than a few seconds, let alone long enough to reach Blast. They sighed mumbling about how easy Blast had made it look. Suddenly a voice said from the bushes, "You're all trying much too hard to achieve your goals. You're overthinking it."

Twilight recognized that voice, it was Celestia! The white Alicorn emerged from the bushes alongside her sister and said, "I got your letter Twilight, and I must say, it was deeply disturbing. However, I had to come see if this pony from the future was real before dispelling it as stress." She looked up to the napping stallion on the cloud. She nodded, "It seems my suspicions have been confirmed."

She sent a magical blast up towards the stallion, but before it could make contact, Twilight yelled, "Princess don't, there's a-" but before she could finish her sentence, the blast bounced off Rainbow Blast's force field and knocked Luna unconscious, causing Twilight to finish her sentence quietly, "Force field..."

Celestia looked at her sister and nudged her awake before saying, "His Ki must be very powerful for it to resist my magic..." She hadn't been able to understand how his Ki could have blocked her magic, but then looked at Twilight and asked, "Didn't you say he was Rainbow Dash's son?"

Twilight nodded and answered, "Yes, and he's able to tap into Rainbow Power, which apparently is carried down through genetics."

Luna said shaking her head, trying to stop her world from spinning from her sister's rebounded blast, "That explains it. If he can access even a portion of Rainbow Power, his Ki also is much more powerful than even ours."

The stallion in the cloud awoke rubbing his head saying groggily, "Didn't I tell you, you can't break through this force field with Ki-" until he saw Celestia and Luna standing down with his mother and her friends. He flew down quickly and said, "My sincerest apologies Princess Celestia, Princess Luna, I had no idea you would be blessing us with your presence."

Celestia was quite surprised at how well mannered the stallion was, considering he was Rainbow Dash's son. But she smiled and said, "So you're the Rainbow Blast I've heard so much about. You're the spitting image of your mother. I understand you're in need of help dealing with somepony named Twilight Black?"

Rainbow Blast nodded and explained his story to her and her sister and said, "That's why I came back. I knew that if I came into a time period where my mother and her friends, as well as the rulers of Equestria were still alive, I might have a fighting chance against Black."

Celestia sighed and said, "Unfortunately, you've done quite a bit more damage than you realize. When a normal pony travels back that far, it creates a ripple in the time-space continuum. You've created a multiverse paradox. Your world and our world are still the same, but by coming back that far, you've severely damaged the timeline, causing your world to split into a second reality."

The news hit Rainbow Blast like a bag of bricks to his face. He started tearing up before breaking down, his head in his hooves. "I just wanted to save everypony! Now I've ruined everything!"
