That's neat, but the "Wa" business still doesn't work with Luigi the way it does with Mario. Like I said, the fact that Waluigi has an upside-down "L" means he's only there to be the opposite of Luigi, unlike Wario, whose upside-down "M" is also a W, the first letter of his name.
It sounds like it makes more sense in Japanese, but then they should've changed it for the North American version. I mean Bowser is just called "Koopa" over there.
It's continuity of theme. That's an upside-down backwards L on Waluigi's hat and gloves.
You can't spell his name with that symbol in English.
You can ask someone in an Asian forum if you don't believe me-they'll tell you the same thing.
How else would you cross "Mario" with "warui"? Warumario would look weird.
I read somewhere Waluigi was going to be called "Warluigi".
I've got some suggestions for new items and power-ups in Mario-related adventure games:
Silver Coins-you collect 200 of these to get a 1-up
Bronze Coins-you collect 500 to get 1-up
Asterisk Blocks-you Mario or Luigi hit them they unlock either Question Blocks or Exclamation Blocks-to heighten the mystery of what items are in them
Acid Power-up-some kind of power up that grants Mario/Luigi acid powers
Drill Power-up-a power-up that grants Mario/Luigi power to dig through blocks, stone and through the ground and enemies
Atomic Power-up-power up that grants Mario/Luigi powers like alchemy, pass through solid objects, radiation blasts, snatch hard-to-get-to items
Beaver Power up-power up that Mario/Luigi beaver-like abilities
Ice Flower-power up similar to Fire Flower-grants Mario/Luigi ice powers
Liquid Power-up that grants Mario/Luigi fluid powers
