Well, here are the other two. I think Luigi - erm, the ShockMaster, came out excellent. Waluigi, not so much. But I'm pretty sure these are their designs.
Make sure to check out my Mario & Wario as well.
Remember in Superstar Saga, how Mario was Fire and Luigi was Electricity? Well, this game would be metroid style, in that it takes place after Superstar Saga and they still have all of their abilities. Likewise, Waluigi has the power of water, and Wario CAN get the power of ice.
In terms of story? There is this old temple sealed with electric lock-type things. There used to be four priests or whatever that had to activate these simultaneously. But, because Waluigi can use water to flood the room, one of Luigi's shocks can activate them all.
What are Waluigi and Luigi up to? Can Wario and Mario stop them? And WHO will save the princess while all of this is going on?
It's ALL up here (taps forehead)
