There could be a Gokaiger fanfiction that focuses on the backstories of each individual Gokaiger. For example, how they came to be chosen for the mission and what their lives were like before joining the team. This would give more depth to the characters and make the story more engaging.
Unique powers of the OC. For example, if the OC has a power that is completely different from the existing Kyuranger members, like the ability to control time in a world where most powers are related to physical combat or elemental control. It adds a fresh element to the story.
You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. These platforms have a large collection of fan - made stories, and you can search specifically for Gokaiger fanfiction using the search bar.
The Doctor from Doctor Who would be an amazing addition. His knowledge of the universe and time - traveling abilities could add a whole new dimension to a Kyuranger crossover. He could help them solve complex problems or get out of tight situations with his wits and his TARDIS.
One idea could be a crossover with another popular space - themed series. For example, the Kyurangers could meet the crew of a well - known starship. They could team up to fight a common enemy that threatens both their universes, like an intergalactic pirate group. This would bring together different technologies and fighting styles.
Sure. One popular Kyuranger OC fanfic is 'The Lost Star of Kyuranger'. It has an interesting plot where the original character is a long - lost member of the Kyuranger team with unique powers. Another great one is 'OC's Adventure in Kyuranger Universe' which focuses on how the OC character adapts to the strange and exciting world of the Kyuranger.
One idea could be a crossover with the Power Rangers. The Gokaigers could team up with the Rangers to fight a common enemy that threatens both their universes. Maybe they start off as rivals, not understanding each other's ways, but then learn to work together as they realize the scale of the threat.
One possible plot is that the Lion Guard discovers some strange energy signatures that seem out of place in their world. These turn out to be related to the Gokaigers' power sources. As they try to figure out what's going on, the Gokaigers also detect a disruption in the balance of their power. They meet up and find out that a powerful enemy is trying to harness the combined power of both the Gokaigers' ranger powers and the magic of the Lion Guard's world. So, they have to put aside their differences and work together. The Lion Guard can use their natural abilities like Simba's roar, while the Gokaigers can use their mecha and ranger attacks to battle this new threat.
How about including characters from Sailor Moon? It would be really interesting to see the Gokaigers interact with the Sailor Scouts. Maybe they could learn some new strategies from the Scouts' magic-based attacks.
The main characters would be a mix from both sides. From the Gokaigers, we would have Captain Marvelous, who is bold and adventurous. He would be a great counterpart to Kion from the Lion Guard. Kion, with his sense of responsibility and the power of the Roar, would be a central figure. Also, other members of the Gokaigers like Joe Gibken, who is more of a tech - savvy character, could interact with the Lion Guard in interesting ways. For instance, he could help the Lion Guard understand some strange technological threats using his knowledge, while the Lion Guard could teach the Gokaigers about the natural magic and powers in their world.
