Who are some good characters to include in Zatch Bell crossover fanfiction?

One idea could be a crossover with Pokemon. Zatch could enter the Pokemon world and team up with a trainer. They could face challenges together like battling against Team Rocket and exploring new regions.

Inuyasha's physical strength and combat skills with his sword could be combined with Zatch's magical attacks. For example, Inuyasha could use his speed to get close to an enemy while Zatch casts a spell to immobilize or weaken the foe. Then Inuyasha could deliver a powerful strike with Tessaiga. Another way is that Zatch could use his magic to enhance Inuyasha's attacks, like making Tessaiga's wind scar even more powerful or giving it additional elemental properties.

One idea could be that Inuyasha's Tessaiga and Zatch's spell book somehow get switched. This would lead to Inuyasha trying to figure out how to use Zatch's magic while Zatch has to deal with a powerful and strange sword. Another plot could involve a common enemy that forces Inuyasha and Zatch to team up. Maybe a demon from Inuyasha's world has found a way to cross over into Zatch's world and is causing chaos, and only by combining their powers can they stop it. A third plot could be a more comical one where Inuyasha and Zatch meet by accident and at first think the other is an enemy but then slowly become friends through misunderstandings and shared adventures.

One popular 'zatch bell zeno fanfiction' might be those that explore the deeper backstories of the characters. For example, a story could focus on Zeno's early life and how he came to be the way he is in the original series.

Sherry is often depicted as a strong and intelligent character. In the context of this fanfiction, she brings her skills and knowledge. Koko, on the other hand, might be more impulsive or have a different approach to magic. Together, they create an interesting dynamic. Other characters from the Zatch Bell series might also make appearances to support or oppose their relationship or the events in the fanfiction.

If it's a crossover with the Legend of Korra, Korra herself would be an excellent addition. She is a powerful bender and has a lot of experience in fighting evil. She and the Trollhunter could learn from each other's fighting styles. Asami could also be included, providing her engineering skills to help the Trollhunter with any technological needs in their battles against the common foes.

For a crossover with a post - apocalyptic world, characters like Mad Max could be involved. He might see the homunculi as either allies or threats in the harsh new world. In a crossover with a cyberpunk world, characters like Neo from 'The Matrix' could be interesting. The homunculi could be part of the complex digital and physical world that Neo navigates, and he could help them understand the true nature of their existence in this new, high - tech world.

In a crossover with 'Fullmetal Alchemist', Edward Elric could be an interesting addition. His scientific knowledge and his search for the Philosopher's Stone could interact with the strange alchemy - like aspects of Rea's resurrection in Sankarea. He might be both fascinated and appalled by what has happened to Rea.

Definitely include Bill Cipher from Gravity Falls as he is the main villain in Weirdmageddon. Dipper and Mabel Pines are also essential as they are the main protagonists in the Gravity Falls story. If it's a crossover with the Over the Garden Wall universe, Wirt and Greg would be interesting additions. Wirt's cautious and somewhat gloomy nature could contrast with the more adventurous Gravity Falls characters, while Greg's innocence could add a different dynamic.

Crash Bandicoot would be a great addition. His goofy and fearless nature would contrast well with Spyro's more noble and magical persona. He could bring some comical moments to the story while also being a strong ally in battles.
