A plot might involve an Alteran knowledge crystal that somehow ends up in the Sargate universe. A young scientist in the Sargate program gets exposed to it. At first, he has no idea what it is, but as he starts to decipher it, he realizes it contains vast amounts of Alteran knowledge. He tries to share this knowledge with his team, but they are skeptical. However, as strange events start to occur around the crystal, they begin to believe him and together they use the knowledge to solve a major crisis in their own universe, bridging the gap between Sargate and Alteran knowledge.
One possible plot could be that a team of Sargate explorers discovers an ancient Alteran device. They struggle to understand its functions using their Sargate knowledge, but as they start to unlock Alteran knowledge within the device, they face unexpected challenges. For example, the device might start to activate a long - dormant defense system that threatens their lives. They have to combine their understanding of both Sargate and Alteran concepts to deactivate it and in the process, they learn a great deal about the relationship between the two cultures.
One option could be a Sargate team leader, like Colonel Jack O'Neill. He has a lot of experience in dealing with different situations in the Sargate universe. Alongside him, an Alteran scientist or a descendent of the Alterans who has inherited their knowledge. The two of them could form an interesting duo as they try to make sense of each other's knowledge and use it to solve problems.
One interesting concept could be the combination of different Alteran technologies. For example, how their advanced energy manipulation might be used in new ways when combined with other elements from the Stargate universe. Another aspect could be the exploration of Alteran knowledge about the Ancients' origin and how that knowledge might cross over to change the understanding of characters in fanfiction.
In the original Stargate series, Alteran knowledge was more of a background element. However, in 'Stargate Alteran Knowledge Crossover Fanfiction', it becomes the central focus. The fanfiction might introduce crossovers with other fictional universes or concepts, which is not a part of the original series. Also, the fanfiction can play around with the Alteran knowledge timeline, perhaps showing how it could have been used differently in different eras compared to what was shown in the original.
Well, perhaps the story could start with a strange distortion in the Metaverse that links the two universes. Some of the characters from Persona 4 start having dreams about the events in Persona 5's Tokyo, and vice versa. This leads to a meeting between the two groups. They then discover that an ancient evil, long forgotten in both their histories, is trying to use the connection between the two worlds to gain enough power to rule over everything. The characters would have to learn about each other's powers and personalities quickly in order to stand a chance against this new foe.
One possible plot could be that Doflamingo somehow ends up in the RWBY world. He might initially try to take over, using his strings to manipulate the Grimm. But the RWBY team discovers his true nature and battles him. Ruby could use her speed to avoid his string attacks while Weiss uses her glyphs to counter his powers.
Well, perhaps Bowser somehow makes a deal with some of the more malevolent characters in the Undertale world, like Flowey. Then Mario has to not only deal with Bowser but also the new threats from the Undertale realm. He might have to learn about the concept of LOVE and EXP in the Undertale world to fully understand how to defeat his enemies. And along the way, he could meet Sans and Papyrus, and they could have some really funny exchanges due to their very different personalities.
Well, perhaps in this fanfiction, the SAO system is corrupted by an Orochimaru - like figure. He wants to use the virtual world to gain power and immortality. Naruto and his friends, along with the SAO players, have to team up. Naruto's positive attitude and never - give - up spirit inspire the SAO players. They all work together to defeat this new threat, with Naruto using his Rasengan in new and creative ways within the SAO world.
A plot could involve the Killzone characters getting access to chakra. Some of the Killzone soldiers might start to learn ninjutsu and this causes chaos in their own military structure. Meanwhile, Naruto has to figure out how to get back to his own world while also dealing with the new threats that this crossover has created. Maybe he teams up with some of the more honorable Killzone soldiers to find a solution.
One possible plot could be that Thor somehow gets transported to the Inuyasha universe. Thor's powerful hammer and lightning powers would be a huge asset or a source of conflict. Maybe the demons in the Inuyasha world see Thor as a threat or a powerful ally to be manipulated. Inuyasha and his group might initially be wary of Thor but then realize they can work together to defeat a common enemy, like a powerful demon that is causing chaos across the land.
Another plot could be that an evil force in the RWBY universe discovers the existence of the Omnitrix from another dimension. They manage to create a device to pull Ben and the Omnitrix into their world. Ben has to adapt quickly to this new world while Team RWBY, who are initially suspicious of him, realizes that he could be an ally against this new threat. They join forces, with Ben using his alien forms in creative ways to combat the Grimm and the evil force's minions.
