In DXC's SotN, she plays more like chibi Maria, but is indeed adult Maria. She can now switch between two sets of subs, and she still has a rolling attack and slide. The triple jump was removed and she now can float vertically up by holding onto an owl.
But yeah her main weapon is the doves she (trained?) in her youth.
Her mode is quite a bit harder than Saturn's, but that's why I like it more. Maria was over-powered in NitM.
