Every wiki has their own rules about crossovers. We seem to be the only one that merges at the drop of a crossover while others would generally make articles on characters outside the franchise describing only what they did in the crossovers with the wiki's franchise. Spyro the Dragon has made multiple appearances in the Crash Bandicoot series, including cameos in games that are not crossovers. That wouldn't merge Bandipedia with the Spyro Wiki. The Mario and Sonic at the Olympic Games series wouldn't merge the Super Mario Wiki with Sonic News Network because they have different rules about crossovers. While the Super Mario Wiki has a shared universe that covers the Mario, Donkey Kong, Wario and Yoshi franchises in full, characters from crossovers like Mario & Sonic and Super Smash Bros are detailed as they appear in the crossover but cannot talk about their original games. And while Super Mario Wiki can have articles on any characters from crossovers, Sonic News Network required that the characters make two playable appearances with Sonic (or after the Mega Man World's Collide event, two major appearances). So how the Ben 10 Wiki did the Generator Rex crossover doesn't really matter. If every wiki had the same rule to merge at crossover events, there would be only a handful of wikis left. Might even be just one wiki covering everything if they get that extreme.
