Well, it could be about Sonic and his friends accidentally stumbling into the world of The Goonies. Maybe they team up to find a hidden treasure that has some sort of power that could either save or destroy their combined worlds. Sonic's speed could be really useful in getting through the various traps and obstacles in the Goonies' territory.
Another possibility is that there's a character in The Goonies who has a special ability that Sonic needs to get back to his own world. So Sonic and his friends offer their help to the Goonies in exchange for this. Along the way, they have adventures exploring the caves and old buildings in The Goonies' town. There could be some really fun interactions between the fast - paced Sonic characters and the more down - to - earth Goonies.
Sonic and Mikey would definitely have interesting interactions. Sonic is all about speed and action, while Mikey is the heart and humor of the Goonies. Mikey would probably be in awe of Sonic's abilities and Sonic would be amused by Mikey's enthusiasm. They could bounce off each other's energy really well.
It might be that Sonic is drawn to the Goonies because of a strange energy or object that they've found. Since Sonic is often involved in protecting powerful items, he senses this and comes to check it out. The Goonies could initially be a bit wary of him, but as they see Sonic's good intentions, they team up. Together, they use Sonic's abilities and the Goonies' knowledge of their area to solve whatever mystery is surrounding the object or energy.
Well, usually in these fanfictions, Tails meets Sonic during an adventure where they both end up at the same place by a series of coincidences. Their meeting leads to an exciting partnership.
In many Sonic Boom fanfictions, Tails often meets Sonic by chance during one of Sonic's adventures. Maybe Sonic is in trouble and Tails shows up to help.
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.
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.
One plot idea could be Dark Sonic having to face a new villain that is even more powerful and is threatening to destroy his world. He has to find a way to control his dark powers even more to defeat this foe.

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.
One possible reason could be a misunderstanding. Maybe Sonic accidentally broke something of Tails' while on a high - speed chase. Tails, being a bit sensitive about his inventions, might get angry and start a fight.
Well, it could be that Sonic is dashing through the forest on one of his adventures when he suddenly hears a strange noise. He follows it and discovers Tails, who is trying to fix his broken plane. Sonic is immediately intrigued by Tails' two tails and his mechanical skills.
