FYI SPOILERZ!!!!! In the game Blaster Master: Blasting Again, the plot has nothing to do with frogs, surprisingly. Roddy, Jason's son, has to actually rescue his sister, Elfie, from the Lightning Beings. The spirit of their mother, Eve, assists him along the way. These should be made into Peach and Toad, respectively. If custom sprites of Irene from Ninja Gaiden can be made, then these characters are also possible.
