#602.5 – Though Tynamo has a special organ that generates electricity, most of their electrical power is used internally to achieve levitation, leaving only a weak current to be used to attack. As Tynamo age, they are able to generate more electricity, which allows them to pursue prey as individuals rather than relying on group ambush.
#603.5 – Eelektrik who are exposed to powerful surges of electricity can be charged with so much energy that they begin to grow new limbs. These Pokemon have a bottomless appetite and will use their developing arms to latch onto prey and drag them into their underwater dens.
Personal headcanon: Snorunt shiver, not because they’re cold, but because it generates the warmth that keeps them not-cold. They like hugs, but they’re fine!
Most Pokémon build nests, and Blaziken are no exception. However, their nests tend to be pretty sloppy affairs made from loose plant material. Since they really only need to hold the eggs (Torchic are up and active within moments of hatching), they really don’t need to be as elaborate as, say, a Chespin’s nest (Chespin nest in trees and the little ones are born blind and deaf; it takes about six weeks before they’re ready to move out of the nest for a bit).
Greninja are hunters, so they like activities they can chase. I’ve heard of trainers using feather toys (a bit like a cat toy), remote-controlled cars, and good old fashioned games of tag with much success.
They are also fascinated by lights, so disco balls and repurposed Christmas lights will provide hours of entertainment. Avoid laser pointers, though. They have been associated with severe eye problems.
With their front limbs being hands, video games are also a possibility if you modify the controller to work for their number of fingers.
