Amanda O'Neil

Amanda O'Neil (アマンダ・オニール) is one of the main characters of Arsenal and the first two seasons of Zero. She is a reporter, former investigative journalist, former blogger, the older sister of the late Colton O'Neil and Hunter Bradley, a good friend of Ben Carone, and the ex-girlfriend of the late Theo O'Connor.

A former member of Team Arsenal, Amanda, although hesitantly, helped Colton's war on crime until he was "killed," in which Hunter assumed the role as leader. Growing tired of her brother's antics, Amanda became a reporter in South City and reunited with her good friend Ben Carone.

Upon meeting Zero, she frequently aided him, eventually discovering his identity and began a relationship with Theo O'Connor. However, upon Theo's death during Xeno's reign of terror, Amanda left Team Zero in order to focus on her career and to cope with Theo's demise.
