A Taxonomy of Wild Pokemon

Partner-seekers

Pokemon that actively seek out humans to partner with
Identified by an extreme willingness to be around and interact with humans
Often either very docile or very excitable
May be seeking a trainer to grow stronger with or an owner to give them the kind of safety that only human society can provide
May be capable of a limited form of the kind of communication domestic Pokemon can use with humans depending on their level of exposure to human society
May still be selective about the kinds of humans they’re willing to partner with based on their own needs. No proud and brave Riolu wants to live their life in a lady’s purse

Pokemon who will approach humans with aggressive posture but will only attack other Pokemon
Usually these Pokemon are seeking a challenge to test their strength or grow
They may make some kind of “come and get me!” display before running off, to goad the human into chasing them
Frequently willing to partner with humans capable of subduing them in battle or tracking them as they flee

Pokemon who move aggressively in human areas and attack humans, property, or unwilling domestic Pokemon
Though most are sympathetic to the lives of wild Pokemon, most also believe the safety of human civilization comes first
Known threats will typically be subdued by local authorities, Rangers, or their proxies and re-habitated away from civilization or incarcerated
While it is legal to capture a threat, trainers are advised to turn them in to the authorities immediately. A healthy Pokemon can leave their ball at any time and any damage caused by a Pokemon is its trainer’s responsibility

Pokemon who avoid human contact as much as possible and resist partnership
These Pokemon flee humans and domestic Pokemon without display and will break out of Pokeballs until fainted
Any Pokemon that continues to run after escaping the first Pokeball is considered a hider
Any fainted Pokemon is considered a hider unless they posed a threat to human civilization while conscious
Attempting to catch a hider is illegal. Even ineffectively chasing a hider is a misdemeanor in most jurisdictions
Still, criminal organizations, poachers, and unscrupulous trainers pose a threat to these populations, especially when the Pokemon in question is rare, special, or considered mystical in some way
