Madara single-handedly washes all of them and with adult Sasuke by his side it's overkillll.
Madara's and Sasuke's rinnegan see through everything. No illusion can affect them. Their eyes are not normal eyes like brehs here are thinking.
Even if Aizen somehow hypnotizes the rinnegan Madara still has a sixth sense called six path sage mode which makes him sense everything even other dimensions.
It is impossible to trick this sense because Aizen can only hypnotize the 5 senses. I also forgot to mention that ninjas have the ability to release themselves from illusions and hypnosis. Many brehs are also forgetting that Madara, Itachi, and Sasuke are all hypnosis specialists. They can also put Aizen in an illusion.
How does Madara single-handedly wash them?
He has powerful abilities like Limbo (completely invisible and invincible clones that are as strong as he is), infinite Tsukuyomi (most powerful illusion in the series), Perfect Susanoo (ultimate defense and offense), Light fang (can cut anything in the speed of light) and Truth-seeking orbs (completely disintegrates objects).
Limbo is the reason why he can handle the all the Arrancars and Aizen by himself. They will not be able to see the clones nor hit them. No attack affects them so this another fail-safe against Aizen's hypnotic abilities.
Many people in this thread think that Madara can't throw nukes like Ulquiorra. He can through nukes way stronger than him. Just look what this guy that was weaker than Madara did.
A person weaker than Madara cut the moon in half and Naruto took this blast to the face like it was nothing.
I also forgot to say that Madara is immortal so they can't kill him.
