Or it could be a story where the Plumbers develop high - tech underwear for Ben to use during his missions, which has advanced sensors and communication devices built into it.
One interesting concept could be exploring new alien forms that Ben hasn't discovered in the original series. For example, an alien with the power to manipulate time on a small scale.

Ben's powers are usually used for good, but in the Warhammer universe, the lines between good and evil are often blurred. So, it would be fascinating to see how he navigates this new moral landscape.
