A sprite for Robin was drawn and animated, but not used in the game after the developers wondered how the game could be arranged to allow for swapping between the two characters. As the Your Sinclair magazine review put it:
The other half of the Dynamic Duo has gone walkies, though the exact reason for this hadn't been concocted when I saw the game. At that time, the finishing touches were just being added to the plot though the game itself was a hundred per cent complete. No doubt some perfectly implausible explanation involving one of Batman's arch enemies will have been thought up by the time the game hits your Speccy.
And so it proved.
