Dr.Animo like Marvel’s Doc Oct is dying and has even regretted his actions, so, he now seeks to pass on his legacy to the one who gave him the most trouble yet motivation to fulfill his research, ie, Ben Tennyson to become SUPERIOR BEN 10 and attain the most beautiful goddesses that either are earth based or the extraordinaire based ones

After an absurdly unlucky death by a stray bullet, teenager Adam Smith is reincarnated at the absolute bottom of the food chain: a tiny snake hatchling in a monster-infested dungeon. 

Cursed with his trademark misfortune but blessed with an unshakably optimistic spirit, Adam must navigate a world where his own siblings are his first predators. 

Armed with a new Evolution System that rewards him for every creature he consumes or defeats, Adam begins his grueling climb from a helpless morsel to a cunning hunter. 

Using his human wit and gradually evolving serpentine abilities, he turns the dungeon's dangers into opportunities.
