This gameover screen applies to all characters in the game, but currently shows Bon-Bon. The rain was to add a dramatic scene. If the last character dies, they appear on this screen and faint/die/go to sleep. This gameover screen is when a character dies in battle normaly, athough it may vary from poison effects like the character turning purple-ish and dying. Or burn, in which they burn till they are dark grey and then have their eyes so funny. Many variations will come! With different music possibly.
The rain does not belong to me. Until i find a more realistic rain this is filler rain, but it can be used in the game.
