Ben 10 vs. The Universe: The Movie

SYNOPSIS

When Vilgax returns to do double the damage on Team Tennyson and planet Earth itself, Ben must go interstellar to save the day.
A mysterious doomsday meteor heads for Earth, causing a panicked Team Tennyson to seek out their scientifically-minded friend, Phil, to help them unlock extra power inside the Omnitrix using a specific key. They're all convinced it's the end of the world as we know it, and they don't feel at all fine about it. They know they have to do something to avert this untimely and apocalyptic disaster! But when Ben uses his newly discovered, unlocked power, he is accidentally rocketed into space, missing the meteor entirely! Turns out it isn't a meteor at all, but a means of transportation that delivers to Earth the all-time scourge of the universe, Vilgax! He's back and he wants the AntiTrix and the key that will unlock it. By doing so, he will have his revenge on Ben!
