Marie, the final boss in Skullgirls, has a lot moves that are either very tricky to dodge or do insane damage (often both). Since she barely moves I can hurt her even by button mashing, but dodging her attacks is the tricky part.
There's certain moves like the big circular shadow on the floor (dash left/right) and the snake of skulls along the floor (jump over) I can dodge, but certain moves like the "assists" coming from behind/in front of you that I can't seem to dodge or block. Her explosion (like when turning into her final form) is another tricky one to dodge, attacking in melee it seems I can't get out of the way once I've triggered it.
How can I dodge Marie's attacks, at least the trickiest ones?
