I'm not bashing anyone's opinions, I honestly think he does have a reason to exist! Because if there's an imposter of Mario (Wario), then there should be an imposter of Luigi (Waluigi). But if he is staying on this wiki, then I'll have to accept that, but I will still respect opinions.

Is Waluigi really that pointless?
It's like saying that if Mario has a girlfriend (Peach), then Luigi should have a girlfriend (Daisy).
We're not saying there shouldn't be a Luigi imposter, but Waluigi did it all wrong. I can't remember the last time he appeared in anything that wasn't a spin-off game, apart from Super Smash Bros. His sole purpose is just to be filler. At least Wario has his own games and a character design that's not as out of place as Waluigi's.
But he's Wario's brother...
Waluigi is not Wario's brother.
He isn't needed at all, and even if he was, he or some other Luigi imposter should have existed way before the spin-off games, then he wouldn't so much be considered filler. If Wario needed a partner so bad, it should have just been a character from the WarioWare games, not just create a partner at the last second, making Waluigi pop out of nowhere.
Waluigi was first created in 2000, and WarioWare games were first created in 2003, but even if Wario did needed a partner, then they could have use a character from the Wario Land games or something. But I'm okay with Waluigi being on the wiki. I can still love him and not hate him, it's not anyone's choice to choose what I should like and what I should not like.
But we may never know what will happen in the future, maybe Nintendo (Hopefully not) will go downhill and make a Waluigi game.
