Meet Crank and Al ... robots on the run.

When the friends arrive at the travelling Iron City, Crank hopes they can all become world-famous powerball stars. But things aren't quite what they expected them to be.

Our heroes soon discover that powerball is more than just a game ... it's a matter of life and death, and it takes more than goals for a team to survive.

A refreshed cover look for this well-loved series, illustrated by the incomparable Mark Oliver. Read on with The Tin Man, Tunnel Racers, Razorbites, The Ghost Sea and Aquanauts.
