As for putting it in bold, that would be against the MoS. It's not a movie, nor is it an actual episode. It's a crossover. There is nothing that contradicts Heroes united with the series. It was never mentioned in either series (Ben 10 and Generator Rex). Alpha, at the speed he was breaking out of his own sphere, would have been free by now, built (or turned into) a Null Void Generator, escaped, and gone after Ben and/or Rex.

Which unfortunately the generator rex series ended before it is resolved.
