If you think Toad is cool, you obviously do not own Super Mario 2 for your Gameboy Advance. I considered setting it on fire just so I wouldn't have to hear his mind-numbingly, IQ-destroying voice.
I think it's his voice
.
Boot to the head!
Anyway, it was actually a closer race than I thought when I clicked the topic. I ended up going with my old favorite, Para Troopa, just because he's the coolest. Koopa Troopa was a contender, but Para Troopa is just a regular Troopa that can fly, which is better.
The other two nominees were Lakitu and the Hammer Brothers. Lakitu, I decided in the end, is too annoying to be voted as my favorite Mario mascot. Throwing spineys everywhere, riding his cloud up in the air like he thinks he's better than me. I don't think so. Lakitu got the boot. (By the way, Lakilester A.K.A. "Spike" did not help Lakitu's score.)
The other person I considered was the Hammer Brothers. They've always been cool, and they had that great hammer-throwing suit in Mario 3. But then I remember that that's the
only thing those guys can do. Jump and throw hammers. I don't think I've ever even seen either of them walk a couple of steps. Jumping and throwing hammers, throwing hammers and jumping, at least when you're a Para Troopa you can fly places and look around at stuff. I mean, how would you like to be stuck for the rest of your life in one spot, and the only thing you could do is jump a few feet into the air, and throw mallets at fat plumbers who want to steal your clothes? Sounds like a demeaning existence to me.
So yeah, in conclusion, Para Troopa is the best.
