What are some interesting ideas for an RWBY Titanfall crossover fanfiction?

One idea could be that the Titans from Titanfall end up in the world of RWBY. They could team up with the Huntsmen and Huntresses to fight a new, powerful Grimm threat that is too much for either side to handle alone. The Pilots could share their advanced combat skills with the RWBY characters, and in return, the RWBY characters could teach the Pilots about the use of Aura and Semblances.

One idea could be a crossover with a mecha anime. Picture the Titans from Titanfall engaging in battles alongside the giant robots from an anime like Gundam. The different piloting styles and technologies could create some really cool action scenes.

One interesting idea could be a crossover of different timelines within RWBY. For example, characters from the past meet the current ones and have to deal with the differences in their worlds. Another could be a crossover of different teams in unexpected ways, like Team RWBY having to team up with a rival team to face a common enemy that is more powerful than any they've faced before. And sometimes, there are crossovers that involve alternate versions of the characters, where their personalities or abilities are slightly different, which can lead to very unique and engaging storylines.

In an 'Attack on Titan' and 'Titanfall' crossover fanfiction, there could be a plot where the world of 'Titanfall' is somehow connected to the world of 'Attack on Titan' through a rift in space - time. The Pilots could be sent to the 'Attack on Titan' world to help in the fight against the Titans. They could introduce their Titan - mech technology to the people there. The story could also focus on the cultural shock that both sides experience. The Pilots would be shocked by the primitive living conditions in 'Attack on Titan' while the 'Attack on Titan' characters would be amazed by the high - tech machinery of the Pilots.

One idea could be the Pilots from Titanfall teaming up with the Normandy crew in Mass Effect. They could share their combat skills and technology. For example, the Pilots' parkour abilities might amaze the Mass Effect characters, and in return, the advanced biotics and tech of the Mass Effect universe could be useful for the Titanfall side.

A plot could revolve around a new threat that affects both universes. So, the RWBY characters and the Titanfall pilots have to team up. The RWBY characters' creativity in combat combined with the Titanfall pilots' skills in mech combat could make for an epic battle against the common enemy. There could be some cultural clashes and misunderstandings at first, but as they get to know each other, they become a formidable force.

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 interesting idea could be the unique character interactions. For example, how the RWBY characters might interact with the denizens of 'heaven' in this fanfiction. Maybe they learn new skills or gain different perspectives on their own world.

One idea could be that Superman arrives in the RWBY world and has to learn about Dust and its powers. He could team up with Team RWBY to fight a common enemy, like a powerful Grimm that is immune to normal attacks but not to Superman's strength. Another idea is that Ruby discovers she has some Kryptonian-like abilities and Superman helps her understand and control them.

One idea could be to cross RWBY characters with characters from another popular anime, like Naruto. Imagine Ruby with the ability to use Naruto's shadow clone jutsu. Another could be a crossover with the Harry Potter universe, where the RWBY characters attend Hogwarts and have to deal with magic and dark wizards. Or perhaps a crossover with the DC universe, with RWBY characters teaming up with the Justice League to save Remnant from a greater threat.
