A crossover could involve the characters swapping abilities. Imagine Tracer from Overwatch having the ability to call in a Titan like in Titanfall 2. Or a Titanfall 2 pilot having the ability to use some of the support abilities of the Overwatch heroes, like Mercy's healing. This would create really interesting and unique combinations in combat scenarios.
One great Overwatch Bastion crossover fanfiction is 'Bastion in Another World'. It has Bastion being transported to a fantasy realm. The author does an amazing job of describing how Bastion's mechanical nature interacts with the magic of the new world.
The plot could center around a new threat that only the combined forces of Titanfall 2 and Overwatch can defeat. For instance, a powerful alien race that has the ability to disrupt technology, which affects both the high - tech Titans and the various advanced weapons and gadgets in the Overwatch universe. So, heroes from both sides must put aside their differences and fight together.
Well, a significant theme is the exploration of morality. In crossover fanfictions, Zenyatta often encounters situations where the moral boundaries are not as clear - cut as in his Overwatch world. For instance, in a crossover with a post - apocalyptic world, he has to decide whether certain actions that seem immoral in his world are acceptable in the new context for the greater good. Another theme is the power of his oracles. When he crosses over, his oracles may function differently, and this exploration of his powers in new settings is also a common theme.

Character interactions play a huge role. For instance, seeing how Mercy from Overwatch would react to the more brutal and often evil characters from Doom. And also, the plot usually revolves around some sort of threat that forces the two universes to collide. It could be a Doom invasion into the Overwatch world or a common enemy that requires both sides to team up. The different cultures within the two universes are also important. Overwatch has its own set of values and teamwork dynamics, while Doom has a more survival - of - the - fittest kind of feel. This contrast can create interesting storylines and character development.
One popular Doom Overwatch crossover fanfiction is 'Doom's Invasion of Overwatch'. It has an exciting plot where Doomfist from Doom enters the Overwatch universe and causes chaos. The story is full of intense battles and interesting character interactions.
One idea could be an Overwatch crossover with the Star Wars universe. Imagine Tracer using her time - traveling abilities in the middle of a lightsaber duel. Another could be a crossover with the Harry Potter world, like Pharah flying on her rocket launcher over Hogwarts. And a crossover with the Marvel universe, where Reinhardt teams up with Thor to fight some powerful villains.
