24. Nemean Lion
- Greco-Roman Mythology
One of the few mythological creatures on this list that is potentially designed around a real creature, the Nemean Lion was quite a monster. When we first hear of the lion, the Demi-God Hercules is told to kill the creature as part of his 12 Labors to become a full God and enter Mount Olympus. The lion has killed a slew of people and Herc must kill it before it takes more humans and animals out. Hercules comes upon the creature, assuming it to be a normal lion only to find out it is much more.
