Although Bruce probably won’t be putting it back on for his upcoming battle with Steppenwolf and the Parademons, his Mech Batsuit from BvS will be back in the Batcave!
One of the biggest BvS Easter Eggs was the inclusion of the fallen Robin suit, which was later confirmed to be Robin No. 2 Jason Todd.
Just like the Robin reminder, the inclusion of the Mech Batsuit implies that Bruce is keeping the memory of his battle with Superman as a grim trophy from how close he came to defeat.
An interesting tour of the Justice League set has revealed that the superhero ensemble will be paying homage to Batman v Superman: Dawn of Justice in a big way.
