Ninten looks too similar to Ness, only has one PK ability unique to him (really having Ninten, Ness AND Lucas would make decloning harder), and is overshadowed by Porky, a central villain in two Mother games. I could see Ninten being an assist trophy at best.I should just add Ninten. It'd be so easy to just redesign him, and it's better than having 3 KI reps.
