Optimus Prime could be an interesting crossover character. His leadership and strong sense of justice would interact in an interesting way with the Thundercats. He might teach them new strategies or they could help him in a fight against the Decepticons.
The Turtles from Teenage Mutant Ninja Turtles would be fun crossovers. Their street - smart and humorous personalities would add a different dynamic to the Thundercats' world. There could be some great action scenes and comical exchanges between the two groups.
Skeletor from He - Man is really interesting. His evil nature and magic powers create a great contrast with the Thundercats' more heroic and noble qualities. It leads to some intense battles and power struggles.
Naruto and Lion - O would be an interesting pairing. Naruto is full of energy and determination, and Lion - O is a noble leader. They could learn from each other's leadership styles. Naruto could show Lion - O how to inspire through his own brand of perseverance, and Lion - O could teach Naruto about the responsibilities of being a true leader. Another interesting pairing would be Sakura and Cheetara. Sakura has her medical ninjutsu skills and combat abilities, while Cheetara is fast and agile. They could train together and exchange fighting techniques.
Another interesting interaction would be between Kakashi and Panthro. Kakashi is a very experienced and laid - back ninja, while Panthro is a mechanical genius among the Thundercats. They could exchange knowledge about combat tactics and technology. Kakashi could show Panthro some of his ninja tricks, and Panthro could introduce Kakashi to the advanced machinery of the Thundercats. And Naruto's interaction with the Thunderian magic would also be really exciting to explore, as he tries to understand and use it in his own way.
In many 'thundercats crossover fanfic', the new storylines that emerge are really cool. When they cross over with something like the Guardians of the Galaxy, the Thundercats' sense of honor and the Guardians' more laid - back attitude create a contrast that leads to interesting adventures. Also, the way the fanfic writers combine the powers and abilities of both sets of characters is exciting.
A Thundercats and Star Wars crossover fanfiction would be really cool. The Thundercats could be in the Star Wars universe, and their unique powers and weapons could be a great addition. Maybe the Thundercats could help the Jedi or the Rebels in their fight against the Sith or the Empire. For instance, Cheetara's speed could be useful in battles, and Tygra's illusions could be used to deceive the enemy.
I think Sasuke and Tygra would make a great pairing. Sasuke has his Sharingan and his complex personality, while Tygra is a strategic thinker with his own set of skills. They could have some intense battles together against common enemies, and also have deep conversations about power and purpose. Also, Kakashi and Panthro would be cool. Kakashi's vast knowledge of ninjutsu and Panthro's mechanical expertise could lead to some interesting exchanges and combined efforts in combat.
One idea could be to have the Thundercats arrive in the Avatar world. Maybe they land near a Water Tribe. The Thundercats' advanced technology and unique abilities would be a shock to the Avatar world. Lion - O could form an alliance with Aang. They could learn from each other's leadership styles. The Thundercats could help in the fight against the Fire Nation with their strength and weaponry.
One possible plot could be that the Thundercats are transported to the Naruto universe. They might be mistaken for powerful ninjas at first. Lion - O could end up learning some ninja techniques and share his sword - fighting skills with the ninjas. Cheetara could use her speed in the same way as some of the fast - moving ninjas in Naruto. And they could all team up to fight a common enemy, like a powerful rogue ninja who has some dark magic similar to the villains in the Thundercats' world.
One possible plot could be that Naruto and his friends are somehow transported to the Thundercats' world. Naruto, with his ninja skills, could team up with Lion - O to fight against a common enemy like Mumm - Ra. Naruto's Rasengan could be a powerful weapon against the dark magic in the Thundercats' realm.
Sasuke is a great character to include. His cool and brooding personality can create interesting dynamics in crossovers. For example, if he crosses over into the world of Attack on Titan, his skills as a ninja would be put to the test against the Titans. Another interesting character is Kakashi. His laid - back yet highly skilled nature can add humor and action to crossovers. He could be a great addition in a crossover with the world of Inuyasha, sharing his knowledge of combat and jutsu.
Illidan Stormrage is extremely interesting. His complex character, with his pursuit of power and his love - hate relationship with his brother, can bring a lot of depth to crossovers. Sylvanas Windrunner is also a great choice. Her undead nature and her thirst for vengeance can lead to some really dark and engaging crossovers. Additionally, Uther the Lightbringer can be a great character to feature. His unwavering faith in the Light can contrast or complement characters from other fictional settings.
