When his cousin Gwen and Grandpa Max start encouraging Ben to not let his guard down when there are new threats coming, they suddenly get an urgent call from their friend Phil, and they quickly travel to his house. After getting there and entering his secret lab in his garage, Phil shows them a meteor heading towards Earth that threatens to destroy all life on the planet. Left with no other options Ben decides to destroy the meteor with one of his aliens but before he does that, Phil tells Ben that the key which is used to unlock his “Omni-Kix” armor is actually in reverse and turning it into its proper lock could unlock the other secret upgrades of the Omnitrix.
