At first, they could be rivals. Ben might think Rex's nanites are too unpredictable, and Rex could see Ben as a bit of a show - off with his Omnitrix. But as they face common enemies, they start to respect each other. For example, when they're both captured by a powerful villain, they see how the other fights and starts to understand their strengths.
One interesting crossover could be their powers combining in a unique way. For example, Ben could use one of his alien forms' abilities in tandem with Rex's nanites. Maybe Heatblast's heat powers could supercharge Rex's nanite - based weapons. Another aspect could be their personalities clashing and then learning from each other. Ben, being more of a carefree hero at times, could teach Rex to loosen up a bit, while Rex's more serious and scientific approach could help Ben be more strategic in his battles.
Another plot could be that an interdimensional rift opens up, and it's causing chaos in both Ben's and Rex's worlds. They discover that the source of the rift is related to the technology of both the Omnitrix and the Nanites. Together, they journey through the rift to find the cause and close it. Along the way, they meet alternate versions of themselves and their friends, which adds an interesting twist to the story.
It could be Ben when he transforms into Alien X. Alien X has near - omnipotent powers. He can manipulate reality on a cosmic scale. In a crossover, he could potentially use those powers to control the Nanites or even restructure Rex's powers in some way. However, he's also very difficult to control, so it's a double - edged sword.
