Vore version of this http://www.furaffinity.net/view/31228636/ even Kasoble has been training a bit under Hanzo a bit and nom some friendly prey she was friends with before she became a hybrid and still is and just wants to keep them safe in her belly from other preds.
Miz has a cute Zorua in his belly he cares for and keeps safe from some that want to kidnap him or harm him.
Malos cares for most snakes that are either weak or get picked on by bigger preds so he helps a Seviper that he saved one day and keeps him tucked away in his belly and Malos stomach acids are like a bath to this Seviper and helps shed his old skin and help strengthen his body from most poisons.
Sonas has a cute noibat in his belly he cares for that his precious Noivern cares for and she trusts Sonas with him.
Transninja likes the little rodents and cares for a pikachu and a raichu that love each other so he noms both and they love a squishy belly to stay in while they embrace each other.
Hanzo loves to care for greninjas that he sometimes treat them like his children so he noms them while meditating and recently one greninja heard of Hanzo and wanted to be inside his belly and he gladly cares for her named Izumi and she loves to nommed by most bigger than her.
Auran likes to nom up Ghosts that are being bad or doing evil things to others but there are some that dont mind being inside his belly like sableye here which he uses her to feed off her dark powers to strengthen his ghost powers and she doesnt seem to mind as long as she gets to be inside his belly. Shigami cares for a froakie that is able to camouflage herself and keeps her safe in her belly and the froakie doesnt mind its comfy inside to her when she needs a rest.
Terra loves canine type pokemon and she cares for a rockruff and noms him to keep him safe from bigger preds.
Blizz cares for a Alolan vulpix that she found in her snowy mountains and protects her from the local preds like sneasal and Weavile but made a peace treaty between some of them but still noms up the Alolan vulpix to be safe to keep her safe.
Evin has her own little fighting dojo some what away from Hanzo's dojo and a cute riolu walks in and is the cutest fighter and wanted to train and when others pick on him she gladly protects him since she sees great potential so she sometimes noms him to protect him.
Una has fallen for a Empoleon that others think he isnt a worthy strong enough penguin to lead and he goes away from his home and finds the Valley that the other greninjas live and one day Una finds him sad and goes up to him and cheers him up telling him that he is strong and others are just putting him down just to mess with him and after awhile falls for her and a piplup follows this empoleon cause it cares for him just as much as she does so the piplup is curious about the inside of a frog and Una tells him why not find out for youself and she noms him up to take care of him and finds her belly satisfying like if he is underwater.
