A plot could involve a race. A powerful being challenges the Sonics from both universes to a race across both their worlds. If they lose, he will take over both. Sonic X's Sonic has his super speed and flight abilities, and Sonic Boom's Sonic has his acrobatic skills and knowledge of his own terrain. Their friends from both sides also get involved. Tails from Sonic X could use his inventions to help them navigate through different terrains, and Sticks from Sonic Boom could provide her knowledge of the hidden paths in her world. In the end, through teamwork and mutual respect, they manage to win the race and save their 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.
Maybe a chaos emerald goes missing from Sonic X's universe and somehow ends up in Sonic Boom's world. Sonic X's Sonic goes to retrieve it with his friends. When they arrive in Sonic Boom's world, they meet Sonic Boom's Sonic and his gang. There's some initial misunderstanding as they think the other Sonic might be the culprit. But as they start to investigate together, they find out that a new villain has been stealing chaos energy from both universes and is using the emeralds for his evil plan. They then join forces, with Sonic X's Sonic using his speed to quickly scout locations, and Sonic Boom's Sonic using his strength to break through obstacles. Their friends also contribute, like Knuckles from Sonic X protecting the emeralds they find, and Amy from Sonic Boom distracting the villain's minions.

He could find a way to open portals between the Sonic X and Sonic Boom universes to steal resources and technology from both. His plans would force Sonic X's Sonic and Sonic Boom's Sonic to team up against him. He could use his robotic creations from both universes, combining the advanced tech from Sonic X and the more rustic, yet effective, machines from Sonic Boom.
