I just got a protien greninja and i was wondering what a good build for it would be for the e4, can somebody help?
What nature is it? In general, there is no definitive best build for Greninja, as part of what makes it so good is the variety of options it has and its general unpredictability. It has good special attack with decent coverage, good physical coverage with decent attack, and plenty of useful status moves.
It has a quirky nature
Neutral nature, right? That could do the job. I recommend Naïve for a mixed attacker or Timid.
