Name: Noelia (Last name unknown)
Codename: Black Panther
E.S.S. Magistrife Division
Noelia has a custom headset that uses the cat ears for communications, as well as being two long-range shotgun mics for hearing over large distances. The microphone used for communication to team members is also embedded in her mask, which has a connection near the back of her ear to connect to the headset, which itself is concealed mostly by her hair.
Her mask is meant to reflect her 'image animal', which is a black panther. It doesn't do that much (or so we think), other than looking pretty cool.
