Who are some good characters to include in a 'Ben 10 Reboot Fanfic'?

The Plumbers could be great characters to include. They could be helping Ben out in space battles, providing backup and useful technology. Characters like Max Tennyson among the Plumbers have a lot of experience and wisdom to offer in such situations.

Definitely Ben Tennyson himself. He's the main character and the one with the Omnitrix. His different alien forms like Heatblast, Four Arms, and XLR8 can add a lot of action and variety to the story.

Obviously, Ben is a must - include character as he is the main user of the Omnitrix. Gwen can also be a great addition as she has her own powers and can provide support or be a source of conflict. Grandpa Max is another good character, with his experience and knowledge.

Well, you could include Zero from the Megaman series. He has his own unique abilities and a cool backstory. In a crossover, he could bring a different fighting style and perspective. Another good one is Proto Man. He could add some mystery and rivalry elements to the story.

Captain America would be a great addition. His leadership and moral compass could guide Ben in some tough situations. And then there's Wolverine. His healing factor and fierce fighting style would contrast well with Ben's more alien - based combat. They could have some epic battles side by side.

One idea could be exploring an alternate universe where Ben gets the Omnitrix at a much younger age and has to learn to control it while dealing with school bullies who are after his power. Another could be a story where the Omnitrix malfunctions and starts giving Ben alien forms that are hybrids of different aliens he already has access to.

You might also consider creating new characters. For instance, a scientist who is a descendant of Victor Frankenstein and is trying to either correct his ancestor's mistakes or continue his work in a more ethical way. Or a journalist who discovers the existence of the monster and decides to expose the story, which would then lead to a whole new set of events and interactions involving all the other characters.

Courtney Whitmore (Stargirl) herself is, of course, essential. But adding characters like Pat Dugan, her step - father, can bring in more family - dynamic elements. He could be a source of wisdom and support for Stargirl in the story.

You could include his sidekick, a witty and agile thief named Lira. She could provide comic relief and also be useful in sneaking around. Another good character would be the wise old wizard, Merlinus. He could offer Arcules advice and knowledge about the magic in the world. And a villain like the shadowy warlord, Zargoth, would be great to create conflict.

The Doctor from Doctor Who would be an amazing addition. His knowledge of the universe and time - traveling abilities could create really interesting storylines when combined with Ben's alien - transforming skills. Another good character could be Naruto. His ninja skills and determination would pair well with Ben's quick - thinking in battle situations. They could learn from each other's fighting styles.
