Mega Construx toy designer Kevin_MCX posted some prototype images of Battle Cat and Mer-Man, which will be released later in 2020 along with a number of other Masters of the Universe figures in the Mega Construx series.
Kevin explained that the following considerations were made when they started designing Battle Cat:
1. Battle Cat should be able to stand on his rear legs
2. Front legs should be articulated and posable
3. Articulated neck to be able to roar and recreate his iconic transformation sequence.
4. Removable saddle and helmet.
5. Ball-jointed legs and tail that are compatible with Breakout Beasts to increase customizing options.
