If non canon, take this crossover for example: http://ben10.wikia.com/wiki/Ben_10-Generator_Rex%3A_Heroes_United

That crossover was specifically non-canon, meaning it was considered a special episode. All characters seen in the crossover episode are added to the wiki, but the pages only have information included within the episode itself. Basically, we use whatever information is given and treat it as a one-time event for now.
