Not good enough yet to have a official main but my most used so far are Pit and Captain Falcon.

Peach, Mr. Game, and Rosalina, buy I play with almost all of the characters that helps me to understand my enemy.

Zelda and Shulk are my two mains in Smash 4.

Zelda has been my consistent main since Melee, though I'm still disappointed that I lost Sheik and that Din's Fire doesn't travel as far as it used to. I just love the range and control over her attacks, plus a good jump and a great recovery.

Shulk is just because I'm a Xenoblade fanatic and his move-set just "feels" really good to me. I love his Vision counter, Backslash practically works as a recovery move, and his kooky jump has great reach (nevermind the awesome literal reach of the Monado itself). Plus, his Monado Arts give him a lot of flexibility for different situations...such as turning on Shield when he's at a high percentage.

Link is a distant third. I didn't like him in previous versions (not since 64 anyway), but in this one he seems more powerful, while still retaining decent speed.

And then I'll fool around with quite a few others to get decent with just to keep it more interesting. Peach and Little Mac are probably the two I use the next most often.

We like Ike! We like Ike!

Always Ike, a heavy fighter with great launching power but still is rather agile and speedy compared to others.
Captain Falcon is always good too.

In this order
-Kirby
- Pikachu
- Zero Suit Samus
- Meta Knight

I'd say Mario, Kirby, Shulk and Samus!

MURABITOOOOOOOOOO

Not much love for Villager here :(

I don't really have a main as me and my friends always play random (find it more fun that way)

Whenever I play for glory however, I don't pick randomly as I still play better or worse with certain characters.

I usually pick Captain Falcon, Luigi, Pikachu, or Toon Link

Sometimes I pick Villager, Duck Hunt Duo, Ness or Bowser

Shulk, Lucina and Toon Link

Not one person has said Palutena? Surprising.

Anyway it shouldn't be that shocking that it's Palutena for me, as well as Zero Suit Samus, Link and Ike. There's not a lot of characters I don't like though.
