The Black Panther is currently sparring with the White Panther, they are both giving it there all, yet they are on equal footing, no matter what the Black Panther does, the White Panther will counter and vice versa. The fight would go on for half an hour, in the end, both knocked each other out, the Dora Milaje had to both bring them to the infirmary.
It happened seven years ago, the current White Panther was but a child, a child from Remnant, when a portal opened from beneath him and sucked him in and he landed in his current world, in the city of Wakanda. He was found by the Kings Royal Guards, the Dora Milaje, he was bleeding and unconscious from the rough landing when the portal pushed him out, they took pity on him, they healed him, when he woke up, they asked where he came from but they did not know where Mistral was, nor was it on their map, the king decided to take him in and train him.
Years later, he was a friend of T'challa the current king of Wakanda, and he gained the title of White Panther, and just like the Black Panther he was given the Heart-Shaped Herb, with it he gained superhuman Strength, Durability, Speed, Agility, Stamina, Reflexes, Flexibility, instinct and Regenerative Healing Factor.
The current king of Wakanda was unconscious, but he is currently speaking with the goddess Bast, he was told that the White Panther needs to return to his world, he was sent to Wakanda by a powerful but dying Deity, to be trained as he was the hope of his dying world, and now was the time he had to return, as the darkness was stirring, and the White Panther is needed. This saddened T'challa as the White Panther was the only friend outside of his family he knows, as King, he was always revered but friendship is not a thing to easily come by, and the White Panther was the only one he has ever called a friend.
When he woke up, he called a meeting, within a few minutes all the important people were gathered in the throne room, there sat in the throne was T'challa, beside him was his mother Ramonda and his sister Shuri, and in the centre of the room was the White Panther.
"White Panther, I have called a meeting here in the throne room regarding you," T'Challa said.
"Is there something wrong, My King," the White Panther asked.
"Nothing is wrong my friend, but I was visited by Goddess Bast, she has informed me that the Deity that has sent you here, is planning to bring you back to your world," T'Challa said.
"What! But this is where I belong, this is the place I hold dear!" the White Panther said.
"That is not true. Yes, you care for Wakanda and you are willing to give your life for Wakanda, but the place where your heart truly lies is in the family that you lost when you got here, and I know you miss them, I see you looking in the distance, remembering your family, there is nothing more important than family after all, and besides, your world needs their White Panther," T'Challa said.
"I understand, My King, but how am I to return to my world, when I did not even know how I got here," the White Panther said.
"The goddess Bast has said that, when the time is right, a portal into your homeworld would open, and we do not know when that is, that is why I had my sister prepare you some farewell gifts…Shuri, if you will," T'Challa said.
"Thank you, Brother. Not we all know that the Panther suit is good, functional but old, that is why I designed this new one, the entire suit sits within the necklace which has the symbol you had on you when you were found," Shuri said, she went towards the White Panther and used her Kimoyo beads to give him control over the suit.
"That is amazing, I guess you did not like the fact it took time to put on the suit," the White Panther said.
"That is right…Now, I have you your own aircraft, I have seen you pilot other Wakandan aircraft and you are superb at it, that is why I designed one for you, it is similar to the Black Panther's aircraft but it is designed with White, Gold and Blue," Shuri said while showing him an aircraft outside the window.
"Hah? How am I supposed to bring that with me? It's huge!" the White Panther said.
"Ah! But all you have to do is to think of it making it small, and it will resize itself to a size that you can carry, the weight is always only 23lbs," Shuri said.
"You are truly incredible Shuri," the White Panther said.
"Oh, come now, I know for the fact that you are capable of the same thing as I am, we have the same IQ after all, the only difference is that I have a lot of time to tinker with the technology, but you don't, you spend most of your time training with my brother and king," Shuri said.
"I thank you for the gifts, Shuri," the White Panther said.
"No need to thank me…Oh and before I forget, I have also packed you some essentials that you might need, I even made you sneakers," Shuri said, this confused the White Panther until he remembered that Shuri makes some lame puns from time to time.
"OH! You mean those shoes that are completely sound absorbent," the White Panther said.
"That's right, now before we end this, I must talk about the feature of your new suit, it is completely bulletproof, I have tested it against multiple different .50 calibre and it completely absorbed the kinetic energy of the bullet, the next thing is that the suit can absorb kinetic energy and store, it can be used to strengthen your hits or you can release all of it and send your enemies flying, and next, the suit's helmet also enhances the night vision you got from the Heart-Shaped Herb," Shuri said.
"Okay, wow. You really went all out to make that suit," the White Panther said, and Shuri nodded and accepted her compliment humbly.
"Now that is all done and it is getting late, it is time to dismiss this meeting," T'Challa said and everyone left the throne room besides Shuri, T'Challa and Ramonda.
"T'Challa, I don't know when the portal for my world would open, but I want to continue training with you until the time come, my friend," the White Panther said.
"That we can do my friend, the same time as always, in my training room," T'Challa said, and the White Panther just nodded before he went back to his room and went to sleep.
A month later, the Portal to Remnant has opened, but unlike the last time, the White Panther was not just sucked into it, and he was grateful for that, he said his goodbyes to the people of Wakanda, the Dora Milaje, Shuri, Ramonda and T'Challa.
"I guess this is goodbye, my friend," the White Panther said.
"It is not a goodbye my friend, a goodbye implies that we will never see each other again, this is merely a see later, as we don't know what may happen in the future, who knows maybe you will return here again someday," T'Challa said, the White Panther hugged each of the people that he knew before he stepped into the portal.
It took an hour of moving within the portal before he arrived in Remnant, he looked around for a moment before he gained a massive headache, the headache contained some information on his family, what happened to them when he disappeared and where they are currently residing, he also received general knowledge that residents of Remnant know, such as huntsman and huntresses, Grimm, the four kingdoms, some secret that the people did not know and lastly his current location, and he was in luck, he was currently in a forest close to Argus, where his sister and his sister in law lives, so that is the location that he chose to go to, after all, seven years of not seeing his family, made him miss them a lot.
With his speed, agility and stamina, he was able to arrive in his sister's place within an hour, to normal people it would have taken a day or two, but for the White Panther, who has superhuman stamina, it was nothing, he looked around before he spotted the house, he went to it and knocked, it was not long until a blonde-haired and blue-eyed woman came out to meet him.
"Yes, how can I help you?" the woman said.
"Hey, Saph. Long-time no see," the White Panther said.
"J-Jaune, is that you!?" Saphron said.
The now man named Jaune was facing a very shocked, very angry and very worried sister, but mostly worried, since he has been gone for seven years.
