To answer UlitameCCC's question, I left hints throughout this fanfi c that implies that Joker and his friends were taken from a time during Persona 5 rather than after, with the world of Smash having a different calendar. I apologize if I didn't make that more obvious.

Jun 8

The Phantom Thieves have met up. Joker spoke up, "Okay everyone, we should send out our calling card today." Ann asked, "And what about Wario? We haven't dealt with facing someone else yet in the Metaverse." Makoto said, "We'll need to create a distraction if we come across him." Yusuke pulled out some red pieces of paper and a brush. "I shall start creating our calling cards now." Ryuji fist pumped and looked at Makoto. "All right, Miss Prez. Let's brainstorm a message." Futaba said, "Just don't let Ryuji think too much. We don't want him getting hurt." "Why do you guys always put me down."

Jun 9

Kremlings were surprised to walk out in front of the tower and find a bunch of calling cards on the ground. A few grabbed some and brought them to K. Rool's throne/control room. He was already talking with Wario. "Why haven't you stopped those thieves yet?" "I've-a been distracted!" A few soldiers came in. "Boss! These things were found all over the beach." "What do they say?" The kremling nervously read the card.

King K. Rool, the selfish reptile of Envy,

You have committed atrocious crimes out of spite for a lack of the Kong's chattels, including stealing, kidnapping, and genocide. You will soon find yourself confessing to all of your previous and current crimes of your own will.

The Phantom Thieves of Hearts

King K. Rool glared at Wario. "You idiot, I told you to stop them and look what happened! You better get out there and stop them before they do anything else!" Wario smiled. "I would, but I-a need to stop by the bank." "WHAT!?" "My-a pockets are empty. Now, if my pockets were full, then I-a wouldn't need a detour." The King's eye was twitching from his anger. "Finefinefine." He looked at a henchman. "Get this man a good sum from the treasury and send him out there." Wario chuckled. "Eheheh. Pleasure-a doing business." Wario followed the goon out the door. K. Rool growled.

This is a declaration of war if I've heard one. All troops, move out!

If there was ever a time K. Rool's palace was on high alert, it was now.

The Phantom Thieves were right in front of the tower. Morgana beamed. "He has to have seen the calling card by now." Makoto said, "Futaba, Yusuke, Haru, keep your eyes open for Wario." They activated their app, knowing full well Wario was entering with them.

Joker commanded, "All right everyone, let's go!" They headed in.

It's not a game, I'm not a robot A.I. challenging you. I'm not a phantom, I'm in your face and, I'm here to see it through!

They found themselves in front of a few shadows. Joker called out to Haru, "Noir, give me your Ice Doctor" Haru tossed him her axe and he swung the axe around like Link, freezing the shadows solid.

Right before your eyes, Watch us multiply

Ryuji was stunned, "When did you learn how to use an axe!?" "From a friend." Futaba called out, "Let's continue to the treasure."

Come to claim our right, it's time.

They noticed in the room with the bomb, the bomb was gone. Ann asked, "Where did it go?" Haru noted, "Looks like we need to hurry."

As our power grows, trying to stop us shows, Might as well go trying stop time!

The Thieves were out side of the watch tower, seeing them loading the bomb into the K. Rool shaped head. Makoto asked, "What do you suppose they're loading it into there for?" Yusuke said, "It seems the watch tower was designed with more than spotting intruders in mind." They rushed to the side of the tower.

So you know that we're out there, Swatting lies in the making

The team started climbing the tower.

Can't move fast without breaking, can't hold on or life won't change.

Wario was running behind them. He started sniffing the air. "Wait. I-a smell a REALLY expensive treasure!" His motivation increased.

And our voices ring out there, took the mask off to be free.

The Thieves and Wario made their way inside.

Fought it out in the debris, now we know that life will change.

The team found that the glowing orb from earlier was now replaced with a crown. Yusuke said, "So this is the source of his mental distortions." Ryuji looked at Ann and Joker, "Hey, does this bring back memories?" Joker smiled, "Our first mission." Back then, Yusuke, Makoto, Futaba, and Haru weren't on the team. Ann noted, "It's just like Kamoshida's treasure." The memories were very bittersweet. Makoto asked, "What did it manifest to in the real world?" Ryuji answered, "A gold medal." Joker grabbed the treasure. Thankfully it was a normal sized crown.

Haru saw something. "Look up there!" There was the bomb strapped into cords. Yusuke asked, "Why would he wire a bomb into his own watchtower?" Futaba's eyes widened. "Guys, what if it's not a bomb at all. Look at those cords. They're spreading all around the room and beyond." Ann asked, "Meaning..." Makoto answered. "It's a power unit."

"Correct! Allow me to give you your reward. Your eternal reward." K. Rool walked into the room, wearing his military outfit. Joker stepped up. "K. Rool." "That's Kommander K. Rool to you. Give me that crown and I promise you'll be killed swiftly." Morgana stepped up beside Joker. "Forget it you rotten king. We've heard of all the crimes you've done, even at the costs of your own subjects lives." Ryuji yelled, "We're taking that crown, scumbag." "NO I AM!" Wario jumped into the scene and grabbed the crown.

"Wahaha! Sorry K. Rool, but this crown is just too good to pass up." Morgana yelled, "What are you doing you idiot!" "Hey, someone-a steals the treasure, he becomes good. Isn't that how it-a works?" Futaba said, "But it needs to be stolen properly. Or else he'll lose every desire...including sleeping and eating!" "Sorry losers, this thing just screams expensive!" He ran off, with the Phantom Thieves and K. Rool in hot pursuit.

They found Wario on ground level, about to get on his motorcycle. Joker sneak attacked him and stole both the crown and his bike. Joker looked at Makoto, "Queen, would you mind?" She smiled, "With pleasure." Makoto got onto the Wario Bike and started it up, driving away! "Hey! That's-a my bike!" He started running after Makoto. Ann smiled. "Not bad, you two."

Just then, a blast came nearby, startling Joker causing him to drop the crown. It rolled away. They looked back at the watch tower to see the K. Rool head fly up. "You insects. I won't let you get away with that crown!" Haru said, "It's not just a watch tower, it's a flying tank!"

"I will destroy this entire base if it means getting rid of you thieves" Morgana said, "Get ready for battle, guys."

The head opened up revealing 20 cannons. It shot lasers at the thieves as they tried to dodge. Joker dodged gracefully with his dancing moves. Ryuji pulled off his mask, summoning a pirate riding a ship. "Blast then away, Captain Kidd!" The pirate summoned a bolt of lightning, attacking the tank. Futaba called out, "Guys, I managed to get a good map while we were in there. If we send some one in to take out that power source, maybe we can succeed." Morgana raised his hand. "Leave it to me." He snuck to a wall of the base and started climbing.

Ann asked Joker, "Got any good tricks to stall him?" Joker smiled. He pulled off his mask and yelled, "Farore!" A beautiful, giant, green woman appeared behind Joker. She was brimming with courage. She launched a severe wind attack towards the tank. Ryuji asked, "When did you get that Persona!?" Joker just smiled. The goddess of courage was born from Joker's strong bond with Link. The tank continued to fight, charging up a beam. Futaba called out, "He's going to attack, start guarding!" The team did as told. The blast o mattic launched a powerful beam, draining them of most of their HP.

Ann groaned, "We should have gotten someone else. Queen's gone and Mona's busy. We don't have as much healing power." Futaba responded, "Don't worry, guys. Support's on the way!" She started typing and everyone's health went up. Ryuji, radioed "Thanks, Oracle." Morgana was watching the battle. "I better get in there. This'll impress Lady Ann for sure." He jumped from the top of the wall, landing on the flying tank.

Ann pulled off her mask and summoned a seductive woman in red. She called out, "Dance, Carmen!" As she launched a fire spell at the flying tank.

Meanwhile...

Wario was still running after Makoto. "Give me back my bike!" She smiled and jumped off the bike, causing Wario to be in her sight. She lunged her spiked knuckles towards Wario. "FIST OF JUSTICE!" She laid a powerful blow on Wario, knocking him unconscious. She tied him up and called out Johanna, strapping Wario on the back. "Sorry, but we gotta make sure you get out with us when we leave." She started riding towards the entrance.

Back with the thieves...

The team were still trying to keep K. Rool occupied. Futaba said, "Here come the buffs." She typed and the team's attack, defense, and speed went up. Joker pulled off his mask and yelled, "Perfect Chaos!" A giant water lizard was summoned. Ryuji said. "Honestly, sometimes I'm jealous of that wild card thing." Perfect Chaos opened its mouth and breathed an Ice Beam towards the tank. Morgana managed to get to the door and entered.

From within, the thieves heard K. Rool. "Hey, what are you...give that back!" From one of the windows, the power unit flew out, crashing the window. The tank started to sputter and smoke, before landing on the ground. Morgana jumped out with K. Rool. K. Rool was furious, as the thieves held him at gunpoint. "It's no fair, you guys have your Personas. Why can't I use those." Joker scowled. "There you go again. Only thinking about what others have that you don't. Well let's see what you think of having something stolen." The thieves jumped up and performed an all out attack.

K. Rool was lying on the ground. "It's no fair. Everyone seems to have it better off than me." Ryuji said, "Only because you keep saying that." Yusuke said, "You have a Kingdom, an Island, a place on the Smash roster and clearly a lot of money if you can create such impressive gadgets." Haru added, "But you keep drinking from a cup that has no bottom." The team could tell Haru was saddened from the reminder. Morgana said, "If you just lived grateful of what you have, you'd have a much happier life. If you go back to your real self and do that, we'll let you live." K. Rool got up. "Fine. I will. If what you say is true will make me happy, I will leave." He vanished. Joker grabbed the crown again.

The whole place started to rumble. "We need to get out of here." Futaba said. Morgana jumped up and turned into a bus. The team got in and drove towards the entrance. Makoto was waiting with Wario tied up. The team got out of the bus, which turned back into Morgana. They all tapped the app and were back on the island.

Ryuji asked, "Did it work." They checked their phones. The palace was deleted from their app. Makoto said, "I guess we just have to wait and see what happens to K. Rool." They called Sonic, who picked them up.

Wario woke up. He was still on the beach. "Wah? Why am I-a tied up? HELP!"
