Least Favourite Character

[SmashBoo]

There's a lot of great characters in the Mario series, like Boo, Gold Boo, Dark Boo, King Boo and Boohemoth. XP
However there's also characters that really make us question why they exist. I know everyone has at least one, so what's your least favourite Mario character? What's the character that you really hate?

I personally never liked Shroobs, my hate is all inside this alien-mushroom enemies. Why? Idk, I just don't like them, I don't like their aspect, I don't like their race, I don't like them at all.

Wario, Waluigi and Birdo are my least favorites.

I hate Lakitu and his army of Spinys.

Waluigi.

I don't hate any characters per se because they're Mario characters, but Nintendo has done nothing with Waluigi. Has he actually appeared in any games outside of the spinoffs (Party, Kart, sports, etc.)?

At least Daisy appeared in SML 30 years ago.
