Deku Scrubs are unique races in the Zelda series and I wish the had a bigger role in the Zelda games, but that isn't so yet. Nintendo can do much with the Deku Scrubs and they just don't do it.
Mogma's are just awesome by looking at them, they have a cool look, they have a cool theme. They have almost every thing, that's why Deku's are cooler.
Since the Lokomo's only are seeing in Spirit Tracks, they are unique to the series, that's why I like them. They come forward by wheels, BY WHEELS?! They can just drive to any destination, gimme that thing and I have the time of my live.
The Zora or the Rito but since Zora isn't an option I voted for Rito. I love the Zora because I love the water. I used to lived near some kind of body of water for the first 17 years of my life, so I spent a lot of time swimming. The world beneath the water is still a mystery with so many beautiful and some times weird creatures. The Zora look really neat as well. I like the Rito because of their overall design. They are really bird anthros if you think about it. Their ability to fly makes them even cooler.
wow I didnt realize there were that many until I saw the options. I think races were really put into zelda with OOT (zoras were just enemies before) so I will have to go with one of those original races... Sure, how about zora... oh wait you forgot the one race that was there even before OOT as they were kinda in the original and they were in ALTTP.
