Origin
Demon Realm
Dark Slimes are a higher-ranking member of the slime family, with the possible exception of a mature Queen Slime. Unlike their lowlier cousins, dark slimes possess a nucleus "slime core" that stores magic power and makes them powerful spellcasters. They are not seen much outside Demon Realms. These creatures have access to a unique form of monsterization called melting, where a captured woman's flesh is dissolved down into a spherical kernel within the dark slime's goo, eventually becoming a new slime core which reproduces the rest of the woman in purple ooze. At this point the captive woman is released as a new dark slime. Dark slimes can also reproduce in the more regular slime family way of semen absorption and fission.
