why not try some of the less heard of nintendo characters, give them a chance to be noticed again, such as ballon fighter, issac(golden sun) or even custom robo!
or stick with the latest ones everyone knows about, such as samus, various star fox characters, or maybe even the ice climbers!

Mudkip or Pit from Kid Icarus. Either one will make your cartoon cooler!
Also, check this out, lol.
