Mix: Start with a Slime

When the sword light fell, Roy realized that he was a piece of slime. Fortunately, he is not completely dead. He can devour the corpses of newly deceased people and integrate other people's skills and flesh and bones into his own body bit by bit. In the eyes of outsiders, he is the most inconspicuous soldier in the corner, but he knows clearly that he is the highest-ceiling alien in the world. Easy CombatDND Hodgepodge
