A plot could involve a time - traveling pony. This pony gets sent to a different era in Equestria's history that has elements similar to the Assassin's Creed universe. There, they meet other ponies who are fighting against an oppressive regime. The time - traveling pony uses their knowledge from the future and Assassin's Creed - like skills they've learned (maybe from a dream or something) to help lead the resistance and liberate the ponies.
The theme of freedom vs. oppression can be incorporated. In My Little Pony, there could be a tyrannical character or group trying to control the ponies. The ponies, like the assassins in Assassin's Creed, fight for their freedom. For example, they could use stealth and cunning to outwit their oppressors.
Once upon a time in the world of Assassin's Creed, an unexpected portal opened and out came Twilight Sparkle from Equestria. She was amazed by the ancient architecture and the hidden blades of the assassins. The assassins were initially cautious but soon realized she could be an ally. Twilight's magic helped them in sneaking past guards undetected, and in return, they taught her some of their combat skills. Together, they embarked on a journey to find a powerful artifact that was said to hold the key to both their worlds' safety.
A cool plot could be that the Templars in the Assassin's Creed world somehow get hold of some ninjutsu scrolls. They start using these to create an army of super - soldiers. The Naruto characters then team up with the assassins to stop the Templars. Naruto could use his Rasengan against the Templars' new warriors, while Altair could use his eagle vision to spot their weaknesses. Together, they could form a unique combat strategy that combines the best of both worlds.
Well, the plot could be centered around Naruto trying to find a way back to his own world. While in the Assassin's Creed 3 world, he gets caught up in the power struggle between the assassins and the Templars. He could see similarities between the Templars' thirst for power and some of the villains he has faced in his own world. Along the way, he might form bonds with certain characters in the game, like Connor, and together they could face challenges that require both Naruto's chakra - based powers and Connor's assassin skills.
A possible plot could involve the Ghost Rider being summoned by an ancient evil in Equestria. This evil wants to use the Ghost Rider's power for its own malevolent purposes. The ponies, led by Twilight Sparkle, team up with the Ghost Rider to defeat this evil. Along the journey, the ponies learn about the Ghost Rider's tragic past and how he became what he is, and they help him find a new sense of purpose beyond just vengeance.
One possible plot could be that Godzilla somehow gets transported to the world of My Little Pony. The ponies are initially terrified, but then they realize Godzilla is there because he's being chased by an even greater threat from his own world. So, the ponies, with their magic, decide to help Godzilla fight off this threat and in the process, they learn about each other's strengths and form an unlikely friendship.
One possible plot could be that some Pokemon accidentally end up in Equestria. The ponies are initially scared but then they realize the Pokemon are friendly. Together, they team up to stop an evil force that threatens both their worlds, like a powerful dark - type Pokemon and an evil unicorn. They use their combined powers of friendship and unique abilities to defeat the enemy.
One possible plot could be that Spongebob somehow gets transported to Equestria. He befriends Pinkie Pie first because of their similar energetic natures. They start having a party together, and Pinkie Pie shows Spongebob around Ponyville. Then, they might encounter a problem like a mysterious spell that's making all the ponies sad. Spongebob, with his positive attitude, tries to help the ponies cheer up and along the way, he meets Twilight Sparkle who teams up with him to find a way to break the spell.
One possible plot could be that Naruto somehow gets transported to the My Little Pony world. He might initially be confused by the colorful and peaceful land, but then he could use his ninja skills to help the ponies when they face a threat, like a powerful dark magic user. He could teach the ponies some of his combat moves, and in return, learn about the magic of friendship from them.
A really interesting plot could be that a powerful villain from Mortal Kombat decides to invade the My Little Pony world. The ponies then have to team up with some of the good - hearted Mortal Kombat characters. Fluttershy, being the kind - hearted pony she is, could try to befriend some of the more aggressive Mortal Kombat fighters and convince them to help protect their world too. The ponies would then have to adapt to the much more violent combat style of Mortal Kombat.
