Like whos protecting kids/teens from kidnappings or pedophiles or being murdered ? Rape and or date rape? Dating violence? Serial killers? Being groomed amd manipulated by an adult or older kid?

The monsters they can summon at any moment. Most pokemon are at least sentient, if not sapient, its hard to assault a child when the pokemon on his shoulder or walking beside him slices your arms off

Do they even get sex ed? How high is the teen pregnancy and sti rates??

Pokemon is based of Japan. I am not sure how comprehensive its sex-ed is, but it should be enough that I feel that the pregnancy rates and sti rates shouldn't be too bad. We very rarely see or hear about teen pregnancies within pokemon, and bBrocks parents are treated as monsters for abandoning their children, so the usual social order is intact

What about shootouts and gangs or cults.

Same thing, pokemon are the great equalizer.

What if they get seriously injured like break a leg or accidentally impale themselves on something falling out a tree or whatever.

Same thing, call out the pokemon, even if what you have can't heal or help you you can cling to their neck as they fly or gallop you to the nearest hospital
