Run Ben 10
Be 10 lost his omnitrix, but that doesn’t mean that bad aliens won’t be after him. He has no choice right now, but to run, at least until he found his omnitrix. But, until then all he can do right now is to keep running and hope that they can’t capture him and make him their punching bag. This is a mission wherein, there are no alien buddies to help so you need to help him get around various obstacles. Remember that he has no alien powers right now so he can fight them and you must help him to reach the other side where it is safe.
