Dexter Draper is a dreamer. At the age of 12, this isn't really such a strange thing, as he prefers to let the very boring (often depressing) real world fade into the background. Time is much better spent indulging in the made-up worlds of fantasy found in comic books and looking through his telescope for a glimpse of the incredible. Sure, aside from the odd comet there generally isn't much to see out there among the "pinholes in the curtain of night", but what if...?
Megatomic Battle-Rabbit is a pilot. We have no idea how old he is, but we do know that he's in a bit of trouble. His ship has been damaged, and he's in for a bit of a bumpy landing (i.e. crashing) near the UK town of West Bromwich. Megatomic manages to the control his landing enough to keep his ship more or less in one piece, but his efforts are made moot when his computer points out that their advanced technology mustn't fall into the hands of a planet full of primitive ape descendants. The ship's self-destruct is activated, and Megatomic is left on his own... a stranger on a strange planet. But it's not long before our heroes cross paths and are brought to the attention of shady government agent Priscilla Parker and her halfwit side kick Gerald Boyce.
But try as he might, it's difficult for a six foot talking rabbit to blend into the back ground at the best of times so when Parker and Boyce are hot on his tail, Dexter and Henry swear to protect their new friend which is handy because an equally strange alien hunter has sworn to find Megatomic, and when they do they're 'going to kill him'.
