Marv throws up his forearms in defense, thick plates of quarts expand across them just in time to deflect the blade and claws. Before Akuma can land her second blow, Marv swing his heavy quartz fists back, slaming his elbows into the train's floor.
There is an awful sound of metal rending and a large portion of the train's floor collapses, taking Marv with it in a spray of sparks and metal. Akuma is left standing, battle ready in front of gaping hole in the train; the sound of the train clacking over the tracks fills the room.
A moment passes, then a large shard of quartz pierces the floor stabbing upwards. Then another. Then another. Marv is holding onto the bottom of the train car trying to reach Akuma through the floor.
