That picture of Waluigi made me realize just how lazy of a character design he really is. Wario was kind of neat, with turning the "M" upside-down making it a "W". Also, with him being the "evil" version of Mario. It felt kind of fresh and made sense.
But when it comes to Waluigi, it's just lame. Adding "Wa" to Luigi!? WTF, goodbye cleverness! And an "L" turned upside-down doesn't become anything more than...well, an "L" turned upside-down. I mean, come on... :/
Even though I think he is kind of funny in an evil, dorky way as a character, he still feels so lame when it comes to the character design. I'm hoping Nintendo didn't believe they were creative coming up with Waluigi. I'm hoping they made him with a lot of self-distance.
