In such a fanfiction, they might start by being a bit skeptical of each other. Modern Sonic is used to his high - speed, action - packed world, while Boom Sonic has his own unique charm and way of doing things. They could end up in a race to prove who's faster, which would be really exciting to read about.
Well, perhaps they meet in a strange new world that combines elements of both their universes. At first, there could be some misunderstandings. But then, they realize that they can learn from each other. Modern Sonic could teach Boom Sonic some advanced speed techniques, and Boom Sonic could show Modern Sonic how to relax a bit and have more fun during adventures. And together, they might face a common enemy that neither could defeat alone.
Well, they could have an epic race. Modern Sonic is all about speed and his cool modern moves, while Classic Sonic has his own charm. They might start competing, with each trying to outdo the other in different terrains. It would be a showdown of different Sonic eras.
Sonic himself is always a popular character in this type of fanfiction. Whether it's Sonic from Sonic Boom or the modern Sonic, he's the central figure. Tails also tends to be popular as he's Sonic's sidekick in both versions. His intelligence and ability to create gadgets can play important roles in the crossovers.
It's hard to say. Modern Sonic is very fast and experienced in his own world. But Boom Sonic has his own strengths, like his more laid - back attitude which could help him think outside the box. It could depend on the situation. If it's a race, Modern Sonic might seem more dominant. But if it's about making friends or coming up with creative solutions, Boom Sonic could shine.
A possible plot for 'sonic meets sonic boom fanfiction' is that a strange rift in the dimensions brings Sonic and his friends from the classic Sonic world into the Sonic Boom world right when they are about to have a big celebration. However, the Sonic Boom characters are initially suspicious of these new arrivals. But as they start to realize that a common enemy is behind the rift, they join forces. Sonic and Sonic Boom Sonic could have a friendly competition to see who can defeat the most badniks during the adventure, which also helps them bond and understand each other's strengths better.
In a 'sonic meets pokemon fanfiction', Sonic could end up in the Pokemon world and start racing against some of the faster Pokemon like Rapidash. Maybe he'd form an unlikely friendship with Pikachu, with Pikachu using its electric attacks to help Sonic out of tough situations, like zapping robotic enemies that Sonic might encounter in this new world.
Sonic, of course, is a must - have. But also Knuckles from both universes. In Sonic Boom, Knuckles is a bit more of a muscle - brained character in a fun way, while the classic Knuckles is more serious about guarding the Master Emerald. When they meet, there could be some hilarious misunderstandings at first, like Sonic Boom Knuckles trying to show off his strength to the other Knuckles, but then they end up teaming up against a common threat.
One idea could be that Sonic from Sonic X accidentally travels to the Sonic Boom universe and has to adapt to the different environment and new versions of his friends. Maybe he teams up with Sonic Boom Sonic to defeat a common enemy that has found a way to cross between the two universes.

One possible plot could be that an ancient evil threatens both the Sonic X universe and the Sonic Boom universe simultaneously. Sonic from Sonic X and Sonic from Sonic Boom have to team up, along with their respective friends. They could start by accidentally crossing into each other's worlds through some sort of interdimensional rift. At first, they might be a bit confused and even a little competitive, but as they realize the scale of the threat, they combine their unique skills. Sonic X's Sonic is more used to high - tech environments and has different power - ups, while Sonic Boom's Sonic is more in tune with his natural island surroundings. Together, they could battle the evil and in the process, learn a lot from each other and their friends, ultimately saving both universes.
