Genesis (Giant)

Genesis is a Giant daughter of Gaea and Tartarus, born to oppose Terminus. During the months Percy spent sleeping in-between the Lost Hero and the Son of Neptune, Genesis attempted to find and kill the sleeping hero. Genesis later reappeared during the Battle of Mount Olympus, alongside the other Gigantes. Genesis succeeded in killing Terminus, who had left New Rome and was protecting the boundaries of Olympus instead. Soon afterwards however Genesis was killed by Annabeth Chase and Bellona working together.
