The storyline "The Circle" was focused on the revelation of a failed assassination attempt on Diana when she was a baby, by four rogue Amazons. These Amazons – Myrto, Charis, Philomela and Alkyone, collectively referred to as The Circle – were Hippolyta's personal guards and were extremely loyal and devoted to her. However, when Hippolyta decided to raise a daughter, The Circle was horrified and considered the baby ill-fate, one who would ruin their entire race. Thus, after Diana was sculpted out of clay and brought to life, The Circle decided to assassinate the baby. Their attempt was foiled however, and the four Amazons were imprisoned. After years, the Circle escaped their prisons with the help of Captain Nazi, and decided to accomplish their previously failed mission and kill Diana. Diana defeated Myrto, Charis, Philomela and then approached Alkyone, who runs off and succumbs to her death by falling into the ocean. The other three Amazons return to their prisons.

I know we went to war with the Amazons, but that was before my time. You know what? I don't wanna die. I'm young. There's shit that I wanna do. I just feel like... I didn't really embrace the sea or the land. I've been a loner my whole life. But being part of something bigger, like this... maybe I'm scared because... I'm meant to..."

Ares then reluctantly engages her in an epic battle while Steve and his comrades attempt to dismantle the plane harboring the mustard gas.
