>>18328991>Dont they have Digimon tourneys in the Digital World?Not really, in Digimon the Digital World is basically a hellhole where monsters fight each other for EXP to evolve, its basically Darwinism on speed.
>Can't you tame them?Nope, also in pretty much every season every kid is limited to one partner monster, if the monster doesn't want anything to do with them then its quite possible that the monster can fuck off or straight up kill the kid.
>release them?The kid can say fuck off surely
>influence their evolutionThe entire concept is fueled around power of friendship = evolution
>corrupt the digiegg?Dark evolutions happen, but they're temporary and nobody wants that shit.
Last time that happened the entire world got almost fucked
