Hydra deeply loved Nemean and decided to fight Hercules herself even if it meant they had to die together. Although she transformed into a snake with nine heads, she could not kill Hercules and he finally defeated her. After that, Hercules dipped his arrows in her blood.
许德拉很爱阿尼，他不会让阿尼去送死，她决定在阿尼之前击退赫五力，哪怕是同归于尽。许德拉来到阿密玛纳泉水旁迎战赫五力。然而，尽管她可以变出九个头形成咄咄逼人之势，但赫五力毕竟是一个伟大的英雄，他勇敢而果断的杀死了蛇妖许德拉，并把随身带的箭全部浸泡在剧毒蛇血里。

That night, Nemean found out what Hercules did and he became a fierce male lion. He rushed at Hercules. Hercules pulled out his arrow but the fur of lion seemed to resist any weapons. Suddenly, Hercules remembered the arrows dipped with Hydra’s blood. He shot them at Nemean immediately. Nemean escaped from first two arrows but was shot by the third one. The arrow with Hydra’s blood shot through Nemean’s heart. He transformed into the young man and fell on the ground and died.
傍晚，阿尼也终于找到了赫五力，他现在是一头浴血的雄狮，朝赫五力猛扑过来。赫五力拔剑与狮子战在一处，但狮子的皮毛似乎任何利器也穿不透，赫五力根本没法杀死他。天色渐渐暗了下来，赫五力想到那些浸毒的箭，于是瞄准狮子射了过去。一支、两支没有射中，第三支箭射中了狮子的心脏。那浸着许的毒血的箭一下子射进了阿尼破碎的心。狮子倒在地上变成了人。赫五力惊诧的看着阿尼，而阿尼一句话也没有说就死去了。

Zeus allowed Nemean to return back to heaven and transform him into Leo in the sky.
后来宙斯让阿尼回到了天上变成了星星，就是那个灿烂如太阳的狮子座。
