I was not 100% sure how to proceed. This dragon looks incredibly powerful, and in the middle ages, being caught using magic could lead to a death sentence.
"Hey, dingus, you left me in Equestria." Alicorn Kronos saus, after leaving a time portal of his own making."
I feel stupid: "Sorry, bro. I got distracted. Luna was right, we need two time anomalies. Let's kill this monster!" He said.
The knight was a bit surprised: "Why art thou accompanied by two colourful mounts, sir knight?" The Ascalon wielder asked, pointing to Alicorn Kronos and Pinkie Pie
"It's a long story. Anyways, how do we kill this thing?" Pinkie Pie asks.
"By God, the horse can talk! It doesn't matter, I met an alien last fortnight, anything is possible. This being is named Dagon, and is a being of pure energy. Anything thou sent at the beast will be sent back a hundredfold. I advise caution, sir knight." The man said, sending energy blasts with the Ascalon at the Dagon creature.
"I am not worried. We have a plan." I say, as I pause time.
"Okay, other me, we sent this SOB to the Void, and then it cannot harm anyone again. Sounds like a plan?" I ask, waiting to see what my Equestrian counterpart has to say.
"Fine by me, bro. Let's do this thing!" Alicorn Kronos says as he begins charging a cosmic attack. I begin to do so as well.
"One...two...three!" We say, sending a massive blast of cosmic energy towards the Dagon, both harming him and trapping him in The Void. I unpause the flow of time, and see what this man has to say.
"What...How...I was in combat with the Dagon, and now it is gone. What witchcraft are you using, sir knight?" The man asks me, unsure of who I am affiliated with.
"Uh...the magic of time?" Both of us say in unison. The knight, weary from battle sits down on a boulder that is a short distance away and listens to what we have to say.
"Elaborate, sir knight and his equine companions. I am Sir George. What art thine names?" Sir George asks.
"Well, my name is Nathan, and the blue guy next to me is me from another planet, and that one is."
"OH MY GOSH HI! I AM PINKIE PIE! YOU LOOK STRONG AND POWERFUL, AND YOU PROBABLY KNOW ABOUT THE AZIMUTH GUY, AND YOU COULD HELP US, AND-"
I sigh: "Not now, we need to explain ourselves first." I say, which quickly calms her down.
Sir George was stunned. How do these three random travellers know about Azimuth?
"How doth thee knoweth of Azimuth, Nathan?" Sir George asks.
"Well, we are from the future, and we need to prevent something from happening to save our reality, and we were told that you were the best person to ask." Alicorn Kronos replies in my stead.
"The future? How odd. Perhaps that could explain your high power level." Sir George says, as he taps the hilt of the Ascalon sword.
"What are you doing? Can I touch it?" Pinkie Pie asks.
"No, my dear, I am contacting Azimuth to see what this quarrel you are having in the future is about. He will arrive momentarily." Sir George says, as a beam of light appears in front of us, quickly revealing Azimuth.
"What's wrong, Sir George?" Azimuth asks, only to notice the three of us standing here. "I don't know any of you, do I?" Azimuth says, puzzled at our appearance.
"Actually, you do, but it's complicated." I say. "We know about the omnitrix you are working on, and we strongly advise you against its development. You see, Albedo, the guy you work with, wants to make his own copy of the device, and it backfires, turning him into a human. Anyways, he wants to get his galvan form back, but it fails, so he kidnaps human children as his own personal army to take over the universe."
"What, Albedo would never do that! How crazy are you people?" Azimuth says.
"Welp, time to show him." Alicorn Kronos says, projecting the past events on the floor, including the human child who was the Celestial Sapien hybrid who nearly killed me.
"My word. I can't make the Omnitrix now. You must be from the future here to warn me. I appreciate the sentiment. The Omnitrix was supposed to be a device to foster peace between Sapient races across the universe. I would have never imagined that it would be used to experiment on human children, or any children for that matter. I will case research on it immediately. Thank you for warning me, kind time travelers.
EQUESTRIA: PRESENT DAY
Ben's Omnitrix completely disappears, leaving his left wrist bare once again. "Damn it, Nathan! You screwed everything up. Why did Paradox pick you to be a time god anyways!"
"I am afraid this is part of the timeline, Tennyson." Said Professor Paradox, who appears behind Ben and Celestia.
"Part of the timeline, what do you mean?" Celestia asks, confused by the current situation.
Paradox adjusts his shirt, and then begins to explain. "What I mean is that this is how time was supposed to progress. The Omnitrix was never meant to last forever, and Nathan and company were supposed to prevent its existence. Obviously, Nathan knows about the timeline's sanctity, and would never agree to this mission if it meant serious danger." Paradox says.
"I call bullshit on that. I deduced that this time erasure would lead to my sister relapsing as Nightmare Moon and using the power vacuum to conquer whole worlds!" Celestia says with urgency.
"Well, you and I both know you are repressing your power greatly. When Luna becomes Nightmare Moon, her power multiplies exponentially. You have Supernova, you know…" Paradox replies.
Celestia knew that Paradox would bring up Supernova, her more powerful, warlike form. Nobody in Equestria, not even Twilight Sparkle, knows how Equestria truly came to be; through blood, death, and tears. Back in the day, Celestia was a power hungry empress who caused a coup in Equestria to usurp the power of the celestial bodies from the unicorn council. She became the first alicorn in the process, effectively becoming Equestria's goddess supreme. She shared this power with her sister, but Luna wanted to keep it for herself. Celestia banished her sister to the moon for her disobedience, and began to create the facade of friendship to make her rule more palatable for new generations. The Elements of Harmony were her invention, inverting her warlike, destructive power for good into six objects.
"I swore never to become Supernova again. When I am her, I lose all control, and become a mad mare like my sister. I cannot, I will not." Celestia says, already anticipating the response from her sister, Tirek, or any other foe.
Suddenly, Ben himself, along with Gwen and Kevin, began to fade away, and vanished completely from this timeline. Thankfully, they did not die, but since the Omnitrix was never made, they returned to Earth, unaware of any of the events about the Omnitrix, ranging from the roadtrip of '11, to fighting Dagon two years ago.
"Oh my god! Did Ben just die!?!?" Celestia said, in anguish.
"No, Celestia, they are alive, but this version of them no longer exists. If there is no Omnitrix, then Ben never became a hero on Earth, so spacetime returned them to Bellwood, California where they are presumably living normal lives, until Luna invades, that is."
EQUESTRIA'S MOON: PRESENT DAY
Vilgax was checking the statistics on his ship, just to see if the beacon for the Omnitrix disappears. It did.
"I have excellent news, my friends. Your hybrid prevented the Omnitrix from existing. The power vacuum exists, and we can begin our conquest. I wish you all the best of luck. I will go and kill Tennyson on this Equestria planet myself." Vilgax says as he enters a pod to land on the planet.
"If this is true, our conquest must begin immediately. Luna, free me from Tartarus. You might be able to now." Tirek says, annoyed that he is still confined in a cage.
Luna uses her powerful alicorn magic to bring Tirek to the moon, which drains her power slightly. "Thank you for this, my pupil. Regain your strength and find your hybrid. We have work to do!" Tirek says with glee.
EARTH: 1096 CE
"If you are really time travelers, then your work must be complete. I have to go to Galvan Prime now to destroy all my work on the Omnitrix." Azimuth says, sad that his magnum opus would never come to fruition because of petty warlords.
"Well… I can throw you a party!" Pinkie Pie says, warping reality to make a party for Azimuth, complete with all Galvan delicacies. I still do not know how she does it. It scares me to my core.
"This is unnecessary, but I appreciate the sentiment, my dear. Return to your respective timeline, before a paradox occurs." Azimuth says, while helping himself to some Galvan treats.
Welp, that says it all. I open a time portal back to the present day, and the three of us return to Equestria.
EQUESTRIA: PRESENT DAY
When we get back, we see something horrific. Luna is back, as Nightmare Moon, and Tirek is destroying Celestia's castle.
"Oh no...Luna never reformed at all." Pinkie Pie said, upset that this is what is happening.
"Oh shit, bro, are you holding it together?" Alicorn Kronos asks me.
Holding it together? I am furious! My stupid costume from before fades away, and the infamous red scales from The Destroyer return.
"Ah, Nathan my dear boy. Glad to see you finish my mission. I am proud of you, truly." Luna says, giggling at herself.
"I...forgave you. I...put aside my grudges... I ended the universe because of you!" I shouted, sending massive power waves through the earth, causing the pebbles in front of me to rise into the air and disintegrate. And this was only at 40% of my full power.
"You were right to forgive me. I am truly sorry for making you a Hybrid, but that doesn't change the fact that my sister abused me and told me I wouldn't amount to anything. Frankly, she is no better than me, right, Supernova?" She asks Celestia, before attacking her point blank, sending her flying into her castle's wall. Even for an alicorn, that kind of attack would definitely break a bone or two.
After the rubble clears form Celestia's launching towards the castle, an orange aura surrounds the impact crater, and a much bigger, more menacing version of Celestia appears; with plasma for wings, and blood red eyes.
"I swore never to do this, but I am thirsty for blood. Bring it on, bitch!"
"Uh, bro? Did you know Celestia could do that?" Alicorn Kronos asks me.
"No clue. We gotta get out of here. Her power level just multiplied by a factor of one million." I say, flying towards Twilight's library. Alicorn Kronos follows me.
If anypony has a plan on how to deal with this, it would be her.
