Kirby is one of Nintendo's most underrated mascots and franchises. In fact if it weren't for his vary existence, there'd be no smash. Smash borrows a lot in it's design, from Kirby. Kirby himself is awesome. He's pink and cute and entry level. Everything hardcore gamers fear. What better way than to berate your enemies, than defeating them with this charming and pink fighter? Also with Kirby, YOU certainly have to work for your kills. It won't be easy. You'll cry and smash things. However... it's a true sign of skill to main him. While everyone is playing the game on easy mode with their quicker, stronger, harder to KO options, you'll be truly testing your skills.
Choose Kirby as one of your mains and feel the satisfaction when winning!
I've loved Kirby since Kirby's Adventure on the NES (I was about five years old at the time; dunno exactly what year I played it, but I do remember that being my first introduction to Kirby). Not much later I'd get a Gameboy and the Dreamland games, which really made me fell in love with Kirby.
On the other hand, I do have to admit that my love for other characters like Mario, Donkey/Diddy Kong and Link is stronger, since I feel that they have better games within their series (like OoT, SMB3, DKC f.e.). This is probably mostly because Kirby games aren't really meant to be all that challenging and are more relaxing.
However, when it comes to Smash, I just pick whoever feels best to play with for me. This time around though (IMO) it seems like all characters have a more unique feel to them, which makes it hard for me to choose.
Kirby currently does give me the best vibe and I've played with him the most (next to Sonic), so will probably go with him as my main (and Sonic as my alt).
Anyway, sorry for derailing the thread! If anyone wants to reply to me, just do so in the [Kirby] social-thread or sending a message directly.
ONTOPIC: If I were to balance Kirby, I'd either give him slightly more KO power or make his hammer more less laggy (which basically equals slightly more KO power).
