I cannot find any information about a crossover between Final Fantasy and Sonic X, specifically mentioning a "6" designation. There's no official game, cartoon episode, or fan-made project widely known by that name. It's possible:
- The name is slightly inaccurate: Perhaps the title is slightly misremembered, or a specific fan-made work uses a similar name. More details might be helpful to narrow down the search.
- It's an obscure project: A very small or less-known fan project might exist, but wouldn't be easily discoverable through general search engines.
- It's a misunderstanding: There might be confusion with other Final Fantasy or Sonic games/shows.
To help me find what you're looking for, please provide more details, such as:
- Where did you hear about this? (A forum, a friend, a website?)
- What platform was it on? (Game console, PC, online video?)
- What was the general plot or premise? Even vague details could be helpful.
Without further information, I can't provide a comprehensive response. However, I can offer information about the Final Fantasy series and Sonic X separately if you are interested.
