Ichigo from Bleach could be a main character. His strong sense of justice and powerful combat abilities would make him a great fit for the nightmarish world of Little Nightmares. He could be on a quest to save the innocent souls trapped there.
Aizen from Bleach might be an interesting choice as well. His intelligence and manipulative nature could add a lot of twists to the story. He could be using the chaos of the Little Nightmares world for his own purposes, either to gain more power or to create a new order.
One idea could be that the characters from Bleach find themselves in the nightmarish world of Little Nightmares. They might have to face the grotesque creatures there using their unique powers from Bleach. For example, Ichigo could use his Zangetsu to fight off the long - armed janitor.
To write a great Bleach x My Little Nightmare fanfiction, focus on the contrast between the two worlds. Bleach has a more traditional shonen anime feel with its battles and power-ups, while My Little Nightmare is full of psychological horror and a sense of helplessness. Use this contrast to create tension and drama in your story. Also, introduce new elements that are a blend of both. For instance, what if a Soul Reaper's zanpakuto is affected by the nightmare world and starts to behave in strange ways? This can lead to some really exciting plot developments.
Ichigo and Steven would be obvious choices. Ichigo is the main protagonist in Bleach, strong - willed and with great power. Steven, on the other hand, is kind - hearted and has a unique way of looking at the world. Their different personalities could lead to some interesting interactions. They could start off as strangers in a new combined universe and gradually become friends as they face common enemies or challenges.
The main character is Six. She is a small girl who is trying to escape the nightmarish world.
The main character in 'the little nightmare story' is a young and fragile - seeming being. There may also be other characters that act as antagonists, such as the grotesque and menacing creatures that the main character has to avoid or outwit. These antagonists are often designed in a very eerie way to enhance the nightmarish atmosphere of the story.
Perhaps in this fanfiction, the Espada from Bleach are somehow related to the nightmares in My Little Nightmare. The Espada could be using the nightmares as a way to gain more power, and the protagonists from both worlds have to team up to stop them. This would create a really interesting dynamic between the two very different universes.
Obviously Naruto himself would be a main character. He would be the one to bring his ninja skills and determination into this strange combination of worlds. Sasuke could also be there, maybe as a rival who has different ideas on how to deal with the Gundam - related threats. And from the Gundam side, Amuro Ray could be a key character. He might be the one who first discovers Naruto and his group and has to decide whether to help or oppose them.
Aizen could be a great main antagonist. He's extremely intelligent and powerful in the Bleach universe. He might see the Miraculous as a means to further his own goals, whether it's to gain more power or to create more chaos. His manipulative nature would make him a formidable foe against Ladybug and Ichigo.
Perhaps there's also a mentor - like character. This could be someone who has had past experiences with the Nightmare Man and provides guidance to the protagonist, sharing secrets about the Nightmare Man's weaknesses and the nature of his existence.

And then there are Princess Celestia and Nightmare Moon (Princess Luna).
