[Pokemon] What's stopping a pokemon from immediately attacking their trainer after they've been caught?
gpt
Because they don't want to hurt their new trainer of course. Encountered wild Pokemon challenge you often because they want to have a trainer to begin with, as it's a common perception among Pokemon that training will bring you strength, glory, a better life, and friendship. After capture, a Pokemon may experience a ton of differing emotions depending on its personality, but almost never outright violence. They range from humiliation of losing, to reluctance to their new trainer, to happiness because it's what they wanted all along.


If a Pokemon is unhappy enough with its trainer, it is capable of running away and even opening the ball by itself, there's nothing stopping it. Even the most unruly or disrespectful Pokemon(see Ash's Charizard) will often stay simply because being with a trainer is a good life. Only the master ball can trick any Pokemon into capture instantly, good or bad. Poke Balls work better on weakened Pokemon because they enjoyed the battle, rather than that it's harder to fight back, otherwise a fainted Pokemon could be caught. A capture is a willing participant with the exception of the master ball, which is why it's dangerous and expensive.
