One interesting idea could be an original character (oc) using the Infinity Stones in unexpected ways. For example, an oc might use the Time Stone to reverse a great tragedy in their world. Another could be an oc having a unique connection to the Stones, like being able to sense their power from a great distance.
Another interesting concept is an oc who is not a skater initially but gets drawn into the world of 'S' because of a personal connection. Maybe they are a photographer who wants to document the amazing skating feats at 'S', and through that, they end up learning to skate themselves and becoming part of the community. They could face challenges like not being accepted at first due to not being a 'true skater', but gradually earn respect.
Another way an oc can interact with the Infinity Stones is by using their own unique abilities or skills to harness the Stones' power. For instance, if an oc has the ability to manipulate energy, they could use that to better control the power of the Infinity Stones. They might also be able to create devices or spells that enhance their connection to the Stones, allowing them to use the Stones' power more effectively in different situations.
One idea could be that the OC discovers the Infinity Gauntlet in a hidden ancient tomb. They then have to figure out how to use it without being corrupted by its power. Another plot could involve the OC using the gauntlet to stop an intergalactic war that's threatening to destroy the universe. Or perhaps the OC has to battle against a powerful villain who also wants the Infinity Gauntlet for their own evil purposes.
One idea could be creating an OC (original character) who is a powerful mage from a hidden dimension. They could have unique powers that disrupt Thanos' plans in unexpected ways. For example, their magic could nullify the power of the Infinity Stones temporarily.
One interesting concept could be the different ways the Infinity Stones interact when characters from different universes come into contact with them. For example, if a character from a magical universe like Harry Potter's world encounters an Infinity Stone, how would their magic react to its power? Another concept is how the possession of an Infinity Stone might change a character's personality or goals in the crossover. A character who was once good might be corrupted by the power of the stone.
One idea could be to create an OC with the power to manipulate stone in unique ways. For example, they can turn themselves into a stone-like form for protection or use stone projectiles in combat. Another idea is to have the OC be a part of an ancient civilization that had a connection to the stones and now they join the Justice League to protect the modern world from threats related to those stones.
One idea could be a crossover between characters from different Disney Infinity franchises in a post - apocalyptic world. For example, Jack Sparrow from Pirates of the Caribbean and Elsa from Frozen teaming up to find a way to restore their shattered universes. Another idea is to have Buzz Lightyear and Stitch on an intergalactic adventure where they have to stop an evil force that is threatening multiple Disney worlds.
One idea could be to have the Infinity Armor cross over with a superhero universe. The wearer of the armor could team up with popular superheroes to fight a common enemy. Maybe they battle an interdimensional threat that only their combined powers can defeat.
One idea could be a story about a new student at Cl Stone Academy who discovers a hidden magic within the school grounds. This magic could be related to an ancient mystery that the academy was built upon.
One idea could be a crossover with 'My Hero Academia'. Characters from Dr Stone could gain quirks and have to navigate a world with both scientific challenges and superpowers. For example, Senku could use his scientific knowledge to analyze and perhaps even replicate quirks.
