Now Ben's stuck in a strange new realm with an alien bounty hunter who just happens to be hunting for him! Ben Tennyson is wanted far and wide for the vaunted Omnitrix that transforms him instantly into any number of amazing and ultra deadly creatures.
Worse yet, the gadget the Forever Knights stole from Aztak's spaceship is a ticking time bomb. Ben must now escape the trap of time, elude Aztak, and find the nefarious Knights before the object blows all living matter within four miles to smithereens!
