Other Games Smash Bros: Who's your main and your strategy? And costumes or something if you really want.

Why not?

Ike: Forward smash and back air win the universe.

Kirby: Stone spam, so pro at this game.

Marth: Grab, smack, smack, smack, smack, side smash. The best part it that when you're done, it always puts them at the range of the sword tip.

Ganondorf: Do that move where you rush people and choke them. Except when you do it above ground, you get to slam dunk them, and suicide bomb. Also, down air sends them to their death at 0 percent damage.

 

King Dedede: dash attacks, spinning his hammer, and the almighty op side smash :P (his up special is useful for getaways and is a more dangerous version of kirby's rock, since you aren't in a rock form)

Little mac: Dodgeing and punching directly after the dodge, he does this strange punch that does well. I also try and build up his gauge to ko punch nubs. Avoiding the side special since it can easily let you sd.

Greninja: Spam the side smash pls

 

Main 1: Kirby: (For 3ds) Up A, Then Side A, Finish with a hammer hit =P

Main 2: Shiek: Gets opponent close up, then (B) Throws needles, then Side A

Main 3: Wendy (Or Bowser Junior): SPAM UP A

 

ROB: throw the opponent off and meteor smash them
use ROB's up smash or up air
Mario: spike them with front air while the opponent is in the air

 

I only bave Super Smash Bros Brawl so my main is Samus (Noob Ikr) But she is really OP if you use the right moves I usually just floor pound, kick, and with zero-suit Samus, I leap around and punch xP

(Samus is a she btw o.o)

 

Bowser Jr: Spam side smash :)
Greninja: Spam neutral B
Yoshi: just too good

 

Pit (Dark Pit costume) : Used for aerial A (Up smash then just spam up aerial) and sometimes grab then attack. And used for spiking my opponents, rarely use Side special to be less predictable.
Dark Pit: For better recovery and slight stronger Side special then has a straight and quick final smash.
Sonic: Use the speed for advantage and you know. Homing attack then spam A - ish. But meh, I never use Sonic that much.
