As you continue to wander the forest a Greninja falls right in front of you, it seems like a regular Greninja expect it's a shiny which is better rare and he's surprisingly muscular as most Greninja usually lack "Greheheh~ don't you know it's dangerous to walk alone, and especially at night?~" He says with a toothy grin and green eyes practically glowing.
