"Roar, Zabimaru!" cried Renji as he destroyed the last of the gun-covered creatures in the stadium. Dormammu and the Millienium Earl were nowhere to be seen.

"That's the stadium cleared up", said Yugi. "But how are the others doing?"

Luffy, Cyclops, Storm, Rocket Raccoon and Allen arrived at the docks to find only a round spiky orange creature and an angular man made of blue jelly playing some kind of card game. The entire place was trashed, so it was clear someone had been fighting here.
"Is all the fighting over?" asked Cyclops.
"I think so", said the jelly man. "Most of the fighters either moved their fights somewhere else, defeated their opponents, or went underwater".
"Maybe we could have got here in time if we hadn't stopped because SOMEONE insisted on getting a bite to eat", said Rocket Raccoon.
"If that was "a bite", I'd hate to see Allen and Luffy at a feast", said Cyclops, shuddering at the memory of how much he had seen those two eat. Then something the two had said struck him.
"What do you mean "went underwater"?"
"There was a man in an orange getup with spiky black hair... or was it blond..."
"No no no, it was green and pink with purple stripes!" said the orange creature.
"Anyway, he was fightin this half-naked guy with little wings on his feet, and he seemed to be winning, and then the other guy pulled him underwater. They both seemed incredibly strong, and both of them could fly. The guy in orange could shoot lasers from his hands too".
"Hey wait, who's that guy?" asked the orange round creature, pointing at a man with orange hair in a black cloak with a red cloud design.

"Almighty Push!" he anounced, a large sphere of pure force forming instantly around him and decimating the wreckage of the docks entirely.
The seven people who had been on the dock found themselves just outside the range of the blast, pulled out of the way by someone or something. They looked up at their saviours to see Kazuki and Thor, along with some unfamiliar faces (at least to some of them); a girl in a school uniform with four robotic arms attaced to metal bands around her legs, a young man with red hair, pointed ears and a horn, a man in an outfit that resembled a Union Jack, and a young man with green hair and three swords on his belt.
"Zoro!" cried Luffy with joy.
"Uh, guys?" said the horned man in an Irish accent "There's six of 'em
now".
And indeed there were. But Zoro just smiled.
The orange-haired man spun round to block an attack from Hiei, who appeared seemingly from nowhere. Another man in silver samurai-style armour ran towards the six orange-haired strangers and slashe at them with a katana. One of the six, the only one to not have orange hair (instead having not hair at all and spikes around his head) attempted to intervene, attempting to grab the blade but instead getting half his hand cut off. The samurai attempted to slash him again, but the man's head opened and an electrical shockwave was released, knocking the samurai off his feet. The leader attempted to stab a black rod of some kind through him, but his weapon was blocked by a young woman with Wolverine-like claws.
"Angel! Psylocke! Now!" she cried. A blond man with white-feathered wings swooped in, carrying a woman in what resembled a dark-blue swimsuit, carrying a pair of short ninja swords

"Almighty Push!" repeated the leader, creating a smaller version of the blast he used before, but still enough to send the five who had attacked flying in all directions.
"Your efforts are in vain", said the leader as Hiei and "Psylocke" landed in front of Luffy and the others, and the other three attackers fell into the sea. "I will destroy you all, in the name of peace".
"Peace?" said Cyclops in surprise.
"If this is peace then I'd hate to see his idea of war..." said Allen.

A huge three-headed dog with similar piercings to the attackers appeared in a puff of smoke. It charged towards the thirteen heroes still on land, but when it got close, Allen grabbed it by its middle throat and threw it over all of their heads and into the building behind them. Only two late did he see that this was mostly a distraction, and one of the six cloaked men was about to stab him through with a black rod hidden in his sleeve. Luckily, Zoro blocked the attack with three swords; one in each hand and a third, oddly, in his mouth.
The other five each targeted a small group of the remaining heroes. Though they tried their best to fight back against them, all of them were soon overwhelmed, and Thor was left as the only one still standing. Despite the fight now being six-against-one, Thor was still able to stop them from landing a decisive blow on him or from finishing off any of his fallen comrades.

"In the name of Asgard, you shall tell me who you are and who sent you here", said Thor.
"I am Pain", said the leader, forming hand seals. "All six of us are"
'Pain?' though Thor. 'I have heard this name before somewhere...'
"And the group who sent me are the Gods of the New World", Pain added as he finished his jutsu. "Planetary Devastation!"

Sorry for the long wait
