Reposting from /vp/ my dumb ideas for a game or anime that is a mix of Pokemon and generic isekai (with a lot of shota fanservice) because I'm bored:
>blonde boy is a regular human
>one day he and many other humans are teleported to a fantasy world by some God
>they're told he's organizing a tournament to determine who'll become the next God of that fantasy world
>the world is the typical middle age fantasy setting but with a single humanoid NPC race that exists to make things easier for contenders
>it also is currently full of semi sentient and sentient monsters
>there's no magic or ancient tech >>for humans<<, so the contenders need to use regular weapons and [INT] to win battles
>however, they have the ability to "tame" local monsters they fight and use them in their battles against other contenders
>by default the monsters have the usual animal/alien appearance, but once tamed their appearance changes to reflect their master's physical appearance, strength and willpower
>this means that if the shota MC tames a monster, the monster will resemble a shota too, like the catboy in that pic (hence the large amounts of shota fanservice)
>if the master is strong enough, the monsters can enter an "unbound" state where they get their original appearance and power back, with the added strength of their master
>masters can trade their monsters like in Pokemon even against the monster's will, but if the new master doesn't have enough willpower to keep the monster tamed it will become "rogue" and escape or attack the new master
>low level tamed monsters look like the typical kemonomini anime characters with few visible monster traits (ears, tail, fangs), while high level ones become more monster-like (although they can change their appearance at will)
>all tamed monsters can use the abilities they had at first, but high level ones can acquire new ones
>the amount of monsters a master can own depends on their willpower and how eager are the monsters to be ruled
