Mario (SSBB)/Neutral attack
A punch-punch-kick natural combo. The first punch can jab lock into a guaranteed forward smash, but is hard to jab cancel into something else. By contrast, the second punch is pretty good at jab cancelling into a forward tilt or down smash, but cannot jab lock. Both punches link well into the kick, but while reasonably damaging, it can't KO until the mid-300%s and has no real follow-up potential.
