I personally love Toadette.
What about you folks?
Donkey Kong would be my favorite
Waluigi, because he's like the opposite of my other favorite, Luigi, but he's too common to be listed.
And that mustache doeee.
I love Lakitu. That sneaky bugger is always throwing stuff from clouds. And he's tenacious, too. You kill him and he just comes back a few frames later to finish the job.
Princess Peach! I don't know why, but I really enjoy how she looks in the newer games. My second favorite would have to be Wario.
Yoshi is adorable. I can't wait to pick up Wooly World.
Luigi. I like him over Mario since he's the less known brother and I prefer playing him in Smash :p
Yoshi and Bowser have been my favourite since I used to play Mario Kart with my older brother back in the day!
I still love Bowser. Big bruiser type characters are my favourite.
Yoshi is the man! By far my favorite Mario character
Yoshi or Luigi. I like them both.
