Its unfortunate that I couldn't jam all the characters into one illustration (for technical and time-saving reasons xP) but when narrowing it down to four I like to think Mario, Kirby, Pikachu and Link are the Nintendo staple boys.
You've got the original plumber mascot, the pink side-scroller alternative, the giant Japanese parent-money-eating franchise, and the only pretty-boy-RPG that Nintendo has ever done right.
Anywho, SSB games are probably the best fighters ever concieved. There are "classics" like Street Fighter, KOF, Tekken etc. But in my opinion, nothing is quite as innovative and fun as the SSB franchise in the genre.
Mario, Kirby, Pikachu and Link belong to Nintendo
