In some Halo Wars fanfiction, there are storylines where the Flood manages to infect both the UNSC and Covenant forces simultaneously. This forces an unlikely alliance between the two sides as they try to fight off the common enemy. It's a unique take on the Halo universe that shows how desperate the situation can get.
One popular storyline could be about a Spartan going back in time to prevent a major disaster in the Halo Wars timeline. For example, they might stop a key Covenant leader from being born, thus changing the course of the war. Another could involve time-traveling to retrieve lost technology from the past to use against the enemy in the present. And some might focus on the ethical dilemmas of time travel, like whether changing the past is really the right thing to do even if it could save lives in the future.
The Halo Wars novels have storylines that are deeply intertwined with the lore of the Halo franchise. There are storylines centered around the relationships between different species. For instance, the complex relationship between humans and the Elites is explored. Some storylines also deal with the internal politics within the UNSC and the Covenant. This includes power struggles, betrayals, and the search for a way to end the long - standing war. Additionally, the discovery of ancient Forerunner artifacts and how they impact the ongoing war is a significant part of the storylines.
In Halo Wars 2 fanfiction, a common theme is the relationship between different factions. One interesting story could be about an uneasy alliance formed between the UNSC and a smaller, previously unaligned alien group against the Banished. This could involve a lot of political intrigue and moral dilemmas as they try to work together while having different goals and values.
In some fanfictions, the Forerunners from Halo could be related to the ancient species in the Star Wars universe. It could explore how their advanced technologies and cultures are connected, perhaps leading to a discovery that changes the understanding of both universes.
In some Star Wars Halo fanfiction, the Covenant from Halo could be integrated into the Star Wars galaxy. They might form an alliance with the Separatists in the Clone Wars. This would bring a whole new dynamic to the war, with the Covenant's unique weapons and ships adding a different level of chaos to the battles that are already raging in the Star Wars universe.
The strategic battles are often reimagined in a cool way. Instead of the typical scenarios in the game, the fanfiction might present battles with unexpected twists. Maybe the underdog side uses a creative tactic that turns the tide of the war.
One idea could be to cross Halo Wars with another popular sci - fi franchise like Star Trek. Imagine the Covenant and the Federation having to deal with each other. Another idea is to have a crossover with a fantasy world, like Lord of the Rings. Maybe the Spartans end up in Middle - earth fighting alongside the elves and dwarves against a new threat that has elements of the Flood. A third idea could be a crossover with a post - apocalyptic world. The Halo Wars units could be trying to survive in a world full of mutants and scarce resources.
Another storyline might involve a secret alliance between a group of humans and elites that is trying to broker peace between their two races. They have to work in the shadows, avoiding detection from the more militant factions on both sides. Their efforts could include sharing technology and cultural knowledge to build a foundation for future cooperation.
A third storyline could be set in a post - war world in Battalion Wars fanfiction. The remaining battalions have to deal with the aftermath, such as rebuilding their homelands, dealing with the psychological trauma of the war, and also facing new threats that emerge from the chaos of the post - war situation. There could be internal power struggles within the battalions as well as they try to redefine their roles.
One interesting concept could be the Spartans from Halo interacting with the Jedi in Star Wars. Imagine a Spartan being trained in the ways of the Force. Another concept might be the Covenant technology being used in the Star Wars universe, like their energy weapons in the hands of the Sith or the Rebels. And also, the Flood from Halo could be a terrifying new threat in the Star Wars galaxy.
