It had been two days since Pain or anyone from Doctor Doom and Orochimaru's alliance had last been seen, and the large gathering of heroes from across the worlds were training in an underground facility under the amalgamated Avengers tower and Kira taskforce headquarters.
Two levels down, two blades met, one metal, the other wood.

"So, Gin", said Deadpool as he and the lazy silver-haired samurai fought. "Any idea why this story hasn't been updated in like FOREVER?!"
"It's probably because the writer was too busy writing "Instruments of Time" or "The Psychic Whatever"", said Gintoki. "I'm surprised we're
even doing this. The writer doesn't usually like breaking the fourth wall".
"Tell me about it", said Deadpool. "I'm in both this AND Instruments of Time and this is the first time... What is that guy doing now?"
His later question was directed at the wall of the room, which now had a large number four on it along with what looked suspisciously like Bo-bobo's face.
"SUPER FIST OF THE NOSE HAIR: FOURTH WALL BREAKS YOU!" yelled the wall in Bo-bobo's voice as it fell over on top of them.

"So, as you can see, our enemies seem to be working in at least two groups", said L, gesturing to a diagram demonstrating two separate groups of enemies. As per usual, L was eating something, in this case a slice of cake. Doctor Strange, Mr. Fantastic and Kurama were sitting on either side of him. Several others were gathered in seats opposite him. "These two groups seem to have widely different methods".
"The group we have encountered most so far is seemingly lead by Doctor Doom and Orochimaru, but given the evidence all may not be as it
seems. The inclusion of Ulquiorra Cifer would suggest Sousuke Aizen is involved, and from what I've heard from Ichigo and his allies, he is
not one to simply follow orders. It is probable he is manipulating the others through his illusionary powers. But even he is not the
potential greatest threat at hand here".
"What do you mean?" asked Ichigo.
"Dormammu's power is truly immense, so much so he can be likened to a god. He is one of my greatest enemies, but Shuma-Gorath may be even stronger. Both have conquered countless alternate timelines, and in some timelines, Shuma-Gorath has even succeeded in killing Death itself".
"Is that even possible?" asked Rukia.
"They seemed strong when we saw them a few days ago, but not THAT strong", said Naruto. "I destroyed one of his tentacles with my Rasengan".
"Those were weaker avatars they presumably summoned to infiltrate this combined world", said Doctor Strange. "At full power, neither of us could hope to defeat them"
"As long as it's just weakened avatars of them, they're not as much of a threat as Aizen", said Ichigo.
"Perhaps", said the sorceror. "But they are probably trying to gains greater foothold on this world. It may have been they who fused the worlds to begin with".
"What about the others?" asked Wolverine.
"As well as those we've already discussed, a shapeshifting demon known as Toguro and a psychic organism known as M.O.D.O.K. are working with Doom and Orochimaru. They may have other allies too", said L. "The other group is only known to consist of Kira and Pain so far, but neither of them can be underestimated by any means. Pain can destroy whole cities with ease, and Kira has the Death Note, a book that kills whoever's name is written in it. On top of that, they probably have other allies. However, having two teams of enemies to deal with may prove to be advantageous".
"How so?" asked Yusuke.

"They may reveal useful information is fighting each other, maybe even reduce each other's numbers..."

"Tell me, what is Doctor Doom's real full name?" asked Light as he sat down at his desk.
"Victor von Doom", said Magneto. "But I told you, the real leader is Aizen, manipulating from behind the scenes. And killing Doom will surely alert them to our presence, if they aren't already".

"I'm aware of that. Trust me on this", said Light, writing in the Death Note.

Victor Von Doom
19:04 15th November
Writes down names of all allies on a sheet of paper, before leaving
headquarters and leaving armour and sheet containing ally list in
dumpster outside central train station. Then travels back to
headquarters and attempts to take out as many allies as possible
before inevitably being killed by them

"Alright Aizen" said Light to himself. "Your move"
