Before you ask no I have not seen Dragon Ball Super but I will be checking out the Manga.
Coming to Equestria
Beerus the Destroyer, the God of Destruction of Universe 7 was bored. He didn't like being bored, he didn't feel like destroying a random world right now and it would be some time before Goku and Vegeta would come to his planet for training. Boredom was not something that a God of Destruction should tolerate and he won't.
"Let's see, should I drive a special to extinction... I have already done it six times this month so one more probably won't hurt..." Beerus pondered in his hammock while his teacher and servant Whis came up to him.
"Lord Beerus, may I make a suggestion?" Whis asked and Beerus looked to him signalling for him to continue. "Well you know the Super Saiyan God you saw in your dream? Well I have similar dreams myself of two beings on equine planets who managed to ascend to Alicornhood. One represents love and friendship; I believe they could be worthy sparring partners if you're interested." Whis told him and Beerus then thought it over.
"On this Equine world, do you think they would have pudding?" Beerus asked remembering that he never did get to have pudding at that birthday party. Whis nodded and Beerus immediately got up and told him to start leading the way as they went to flying.
After about 22 minutes (as he remembered roughly the episode of a stand anime or perhaps cartoon). He would find these awakened Alicorns to have a worthy brawl and more importantly...
He will have his pudding!
Discord yawned as he grumbled to himself heading to Rarity's holding a large amount of expensive clothing fabrics that she asked him to get for her. It was a bit hard getting used to doing favours as part of this whole 'friendship' thing but hey it was not much.
He stopped when he was near the outskirts of Ponyville hearing a voice say 'here we are Lord Beerus...' He could not have heard that right, it couldn't possibly be...
Just to be sure he turned and paused with his mouth slowly dropping to the ground (quite literally in fact) in horror as he spotted Beerus and Whis walking to the direction of Ponyville. Dropping all the fabric into a puddle (he would get an earful from Rarity about it later but that did not matter in the slightest), he began floating about in panic.
"What do I do, what do I do..." Discord thought walking in circles as he then remembered Twilight and thought she would be the best pony to go through at the moment so they can explain it to the Princesses. They would not take his warning thinking it was just a prank that seriously but they would if Twilight backed her up!
He then rushed to the inside of Twilight's Castle running so fast that he knocked Twilight and Spike over. "Twilight, I need your help in organising a full evacuation of Ponyville, no Equestria! We should probably evacuate Yakyakistan as those Yaks greatly amuse me..."
Twilight then got up and used a spell to close Discord's mouth for the moment; she was concerned about why Discord was panicking like this but cautious just in case it was just one of his little Pranks. "Discord, what is it? What is so important that you want me to evacuate practically the entire world?" Twilight asked thinking that this was unusual even for him.
"I saw them, someone who poses a great threat to us all... trust me in saying that trying to fight him would be futile and pointless! Beerus the Destroyer is here!" Discord told her and Twilight shook her head.
"look Discord, I never heard of this Beerus the Destroyer but I am sure my and my friends can use the Magic of Harmony to stop him if he poses a threat to the world..." Twilight told him softly only to get taken by the neck and brought to Discord's face.
"Twilight listen to me, this is the one foe the Magic of Harmony can't beat! Let me tell you this, do you know why there are not anymore Draconequus' about?" Discord asked and Twilight shook her head. "Beerus came to my home dimension one day and slaughtered most of them! I am telling you that even the Windigos feared him!" Discord told him and Twilight gulped as Discord dropped her. Spike then help her up.
"Look Discord, if it makes you feel better I will have Spike take a letter and see what Princess Celestia has to say." Twilight told him and Discord humped. Spike got a quill and paper and Twilight then began saying out loud:
Dear Princess Celestia
Discord had come to my palace wanting me to evacuate all of Equestria saying he spotted someone called Beerus the Destroyer in Ponyville. I am sure it's not something to be worried about but I wanted to let you know to make sure.
Your faithful fellow Princess Twilight Sparkle
Spike then sent the letter through his dragon fire and the three of them waited for a few uncomfortable minutes. Discord was tapping his foot impatiently and Twilight was growing nervous until Spike coughed up a reply. He then read it out loud:
Twilight
If Beerus the Destroyer is truly back as Discord claims then... I ask that you remain calm and watch over Beerus and I must beg of you to make sure that absolutely nothing upsets him. Princess Luna and I will let Princess Cadence know and we will be in Ponyville as soon as we can. Last time Beerus was here in Equestria over a thousand years ago, the Draconequus and Alicorns were almost driven to extinction. I ask that you not worry and make sure Beerus is not upset. Please Twilight, don't let anypony try and pick a fight or argument with him, the risks are too high...
Princess Celestia
Twilight and Spike had their mouths open as Discord shot them a gloating smirk. If this truly was a foe that they cannot fight with their magic then... Twilight then ran out the door calling for Spike and Discord to follow her as they set out to find Beerus.
