At the beginning, yes. But after a few episodes he joines ben and Gwen.
the new episodes are not coming cause Ben 10 and Ben 10 alien force are produced by different creators, see ep 59 for more details
never ben10alien force will be followed by a brand-new series called ben10evulution
actaully in one of the episodes he reveals it to his parents, but as for the world, that's in ben 10 EVOLUTIONS
Apparently there isn't, as the show is being replaced with Ben 10: evolution. It will be a continuation of the show under a different name and the events of the season finale of Ben 10: Alien Force. It follows Ben Tennyson after his identity is revealed at an age of sixteen, hence he is a mega superstar, as seen in the future episodes of Alien Force. I hope Kevin doesn't die and comes good again, he's my favourite=)
