This post is just a place for me to post little bits of info, as questions are asked. :3
Strength between each Numa varies. Those who fight more, and fight better, will obviously be stronger than those who do not... but as a general rule:
+ Males are stronger than females.
+ Females are faster than males.
+ Coffees are significantly stronger than regulars.
+ Evolved regulars match Coffees in strength.
+ Pocket Numas are the weakest of all Numa sub-species (obviously, they're tiny!) but they're uncatchably fast.
Can males fly and/or can females swim? The answer is yes, but only minimally. Numas without large wings (regular males, all Coffees) can only fly small distances, only going so high... they mostly just glide. Similarly, females can swim, but not nearly as quickly as males, nor can they hold their breath as long or maneuver as well underwater.
Newborn pups are fed by licking away at their parent's horns. The horns of Coffees are naturally caffeinated, whereas the horns of regulars are not; as such, only adult Coffees can feed Coffee pups. Pocket Numas feed their young by allowing them to lick at their Pokéballs (which are made of the same substance as regular Numa horns.)
